Laser Safety Information

The GigWorks 1062/16 MKII Switch may use Class 1 lasers to communicate over the fiber optic conductors. The U.S. Department of Health and Human Services (DHHS) does not consider Class 1 lasers to be hazardous. The International Electrotechnical Commission (IEC) requires labeling information that states that the lasers are Class 1. The following notices are given so you understand the laser’s certification and classification, the laser type and their use in the fiber optic transmitters, their usage restrictions, and labeling requirements.

Certification and Classification Information

The GigWorks 1062/16 MKII Switch may contain fiber optic interfaces known as optical GigaBit Interface Converters (optical GBICs). Within each system, the optical GBIC component assemblies are located on the front of the chassis. In the U.S., all models of the optical GBIC product family are certified as Class 1 laser products that conform to the requirements contained in the Department of Health and Human Services (DHHS) regulation 21 CFR Subchapter J. The certification is indicated by a label located on the plastic retainer of the optical GBIC assembly. Outside of the U.S., all models of the optical GBIC product family are certified as Class 1 laser component assemblies that conform to the requirements contained in the International Electrotechnical Commission (IEC) standard IEC 825-1 (11/1993) and the CENELEC (European Committee for Electrotechnical Standardization) European Normalization standard EN 60825-1 (1994). The German testing institute VDE assigned the regulation number 3642* to the certificate of conformity for the product family. The VDE conformity mark is also located on the plastic retainer of the optical GBIC assembly. The DHHS conformity label and the VDE conformity mark may not be visible when the optical GBIC is installed in the system level product. A drawing, later in this section, shows the Class 1 information label required by IEC 825-1. On this system, the label is located on the top of the chassis.

Another Class 1 information label is supplied with the equipment. This label is installed by the user during the installation procedure. The user is to install the label where it is clearly visible whenever access to the optical ports is possible.

• Note:

VDE regulation number 3642 is for the IBM OLC/OLM/SOC product family.

Optical GBICs

Each optical GBIC is a single communications port. Each communications port consists of a transmitter and receiver optical subassembly. The transmitter subassembly contains internally a semiconductor laser diode of either: 1) the gallium aluminum arsenide (GaAlAs) type emitting in the wavelength range of 770 to 860 nanometers (commonly referred to as Shortwave (SW)) or 2) indium gallium arsenide phosphide (InGaAsP) type emitting in the wavelength range of 1270 to 1355 nanometers (commonly referred to as Longwave (LW)). Both SW and LW discrete laser diodes are classified as Class 3B laser products rated at 5.0 milliwatts peak power. Once they are incorporated into the optical GBIC, the product’s automatic power control and power monitoring system maintains the average power that exits from an open fiber at a value below the Class 1 limit for either SW or LW laser link products. In addition, for those GBIC products that contain Open Fiber Control (OFC) the optical fiber link between two GBIC ports is continuously monitored by the open fiber link detection and laser control safety system; in the event of a break anywhere in the path, this control system prevents laser emissions from exceeding Class 1 levels. For the non-OFC links, the optical power from the laser transmitter is controlled and maintained at a lower power level such that the power emitted from either an open fiber or an open laser transmitter is guaranteed to be below the Class 1 limit. Class 1 laser products are not considered to be hazardous. There are no user maintenance or service operations or adjustments to be performed on any optical GBIC.

Usage Restrictions

Failure to comply with these usage restrictions may result in incorrect operation of the system and possibly points of access that may emit laser radiation above Class 1 limits established by the IEC and the U.S. DHHS.

1. Optical GBICs are designed and certified for applications using point-to point optical fibre links only. Use of the product with multiple input or multiple output optical links (for example, star couplers) is prohibited since it is incompatible with the product’s design and function and may require that the user certify the laser product again for conformance to the laser safety regulations.

2. An optical GBIC that contains OFC will not allow normal data transmission on the optical link unless it is connected to another GBIC that also contains OFC with the same OFC timings.

Labeling Requirements

There are no caution or danger labels required for use of the optical GBIC since it is a Class 1 laser component assembly. Within the U.S., the only laser safety label required is the certification label that already appears on the plastic retainer of the optical GBIC assembly. Outside of the U.S., the IEC 825 laser safety standard requires that the system level product have a Class 1 information label permanently attached and clearly visible whenever access to the optical ports is possible. This label is supplied with the equipment and applied by the user during the installation procedure. Refer to the Installation section of this manual. An example of the IEC Class 1 information label and its dimensions, suitable for use in most European countries, is shown below. The label consists of black printing on a yellow background. The languages represented on this example label are English, German, Finnish, and French and represent the minimum set for acceptance of a Class 1 product in most European countries.

Section 1 GigWorks™ MKII-16 Switch

Model MKII-BASE16 General Description

GigWorks™ MKII-16 Switch Model MKII-BASE16 General Description

The Switch is the Fabric component of a Fibre Channel compliant network. Figure 1-1 is an illustration of the Switch.

Figure 1-1 GigWorks MKII-16 Switch

The Switch uses a two-dimensional switching architecture consisting of spacedivision and time-division interconnection techniques to implement the Fibre Channel (FC) fabric. Space-division switching allows direct connections (FC Class 1 service) among all ports on the Switch. Time-division switching allows timemultiplexed connections (FC Classes 2 and 3) among all ports on the Switch.

Major Fibre Channel Port Features

Major Fibre Channel port features include:

• The Switch chassis has16 ports. Each port operates at 1062.5 megabaud.

• Half of the ports may be FL_Ports (Arbitrated Loop) or standard F_Ports (Fabric) depending on their use. The remainder of the ports are F_Ports. Refer to the Front Panel Controls and Fibre Channel Ports paragraphs later in this section for more information.

GigWorks MKII-16 Switch Model MKII-BASE16

59003-01 Rev. A Installer's/User's Manual

General Description

• All ports used as F_Ports support Class 1, Class 2, Class 3, and Intermix Fibre Channel service. Refer to the Reference Information appendix for more information.

• All ports support the maximum Fibre Channel frame size (2148 bytes) for all classes of Fibre Channel service.

• All ports used as FL_Ports support Class 2, and Class 3 Fibre Channel service. Refer to the Reference Information appendix for more information.

• As an option, any or all ports can be Trunk Ports (T_Ports). T_Ports support all three classes of service and interconnect chassis in a fabric composed of multiple Switch chassis. T_Ports also “self discover” and are available in groups of four. Any time you use one port in the group as a T_Port, all ports in that group are T_Ports. The port groups are 1-4, 5-8, 9-12, and 13-16. That is, if you use Port 6 as a T_Port, Ports 5, 7, and 8 can only be used as T_Ports or not used at all. Contact your Ancor sales representative or sales engineer for information about using your chassis in a multi-chassis fabric.

• Ports are supported by GigaBit Interface Converters (GBICs). GBICs contain the transmitters and receivers that connect to the interconnection media. Each GBIC is “hot pluggable”.

• You may populate 2 to 16 ports with GBICs. The choice of ports and GBICs is yours.

The Switch has been validated with GBICs that support a variety of interconnection media. Refer to the Fibre Channel Ports paragraphs later in this section for more information.

Major Switch Management Features

The Switch supports management through:

• the Windows NT™ or Windows 95™-based GigWorks MKII Switch Utilities,

• a Trivial File T ransfer Protocol (TFTP) server , and

• a built-in SNMP Agent.

• Optionally , the GigWorks MKII Switch Web-Based Management Interface application is also available. This management interface is a Web-based (Java) application.

The Switch Utilities require an Ethernet connection to each managed chassis. The Webbased Switch management application can manage multiple fabrics and can manage multi-chassis fabrics through an Ethernet connection to any one chassis in the fabric.

The following is an overview of the major features of the Switch chassis:

• You have the option to add a second power supply for total power supply redundancy. When there are two power supplies, they each become “hot pluggable”. Refer to the Power Supply paragraphs later in this section and also to Section 4 for Removal Replacement procedures.

• You have the option to add control firmware that allows your MKII Switch chassis to operate in a multi-stage interconnection fabric with other MKII Switches. Switches in this multi-stage fabric may be connected in either two-stage or three-stage topologies. These multi-stage topologies use crossconnecting (not cascading) for the fewest number of fabric hops between users. Refer to the Reference Information appendix for more information.

• The Switch undergoes a battery of Power-On-Self-Tests (POSTs) each time it is powered-up. POST provides one pass through the battery of tests but does not test the GigaBit Interface Converters (GBICs). The POST uses the Heartbeat LED to indicate pass or fail test conditions. Refer to the LED paragraphs later in this section and the POST paragraphs in the Troubleshooting section.

• The Switch contains a Continuous Test button on the front panel that, when placed in the TST (T est) position, places the Switch in continuous test mode. This continuous test mode requires that Loopback Plugs (provided with GBICs

ordered from Ancor) be placed on each port populated with a GBIC so that the GBICs may be tested. Refer to the LED paragraphs later in this section and the Continuous T est paragraphs in the T roubleshooting section.

• LEDs indicate the status of the Switch and each port. Refer to the Front Panel LED paragraphs later in this section.

• The Switch contains an Ethernet connector that provides a connection to a management station. The management station, running the Ancor Switch Utilities or SNMP, provides a means to access such things as the Fibre Channel Management Information Base (MIB) and upgrade the control firmware held in the Switch’s Flash memory. Refer to the Chassis Back paragraphs later in this section and the Switch Management Section of this manual for more information.

• The Switch chassis is shipped from the factory physically configured with rubber feet on its bottom that allow it to sit on a flat surface and stack. Mounting brackets (in a separate packet shipped with the Switch) allow you to mount it in a 19-inch rack. When mounted in a rack, the Switch must

be supported by rails or a shelf. Refer to the Installation section for the install procedure and the Reference Information appendix for the dimensions and type of rack.

Fibre Channel Ports

Refer to Figure 1-2. The 16 ports are numbered left to right 1 through 16. Ports 1, 2, 5, 6, 9, 10, 13, and 14 are F_Ports or FL_Ports depending on their use. These ports discover their function (F or FL_Port) each time the cabled node executes a Fibre Channel Login. Therefore, if the port cabling is changed from a connection to an N_Port to a connection to an NL_Port or vise-versa, the function of the connected Switch port will also change appropriately. These ports are marked on the chassis front with a small white triangle on each side of the chassis opening. The remaining Switch ports are F_Ports.

Port numbers are marked on the front of the chassis for a single-stage (one chassis) Switch fabric.

General Description 1-7

General Description

Currently, the following GBICs are certified for use:

Short-wavelength fiber optic GBICs 100-M5-SL-I or 100-M6-SL-I with Open Fiber Control (OFC) support connection to legacy 1062 megabaud Fibre Channel networks. The Optical Link Modules (OLMs) used by many legacy Fibre Channel transmitters and receivers contain an internal OFC system. The OFC is a safety interlock that detects when the optical link has been interrupted and shuts down the laser. Each of the two transmitters in the Fibre Channel link will try periodically to reestablish the link. The laser pulse duration for this re-connect operation is very short. Newer designs of fiber optic transmitters with lower launch powers (like those used in GBICs) do not generally use OFC. However, if one end of a Fibre Channel link has OFC, then both ends must have it.

Short-wavelength fiber optic GBICs 100-M5-SN-I or 100-M6-SN-I without OFC to support connection to new non-OFC Fibre Channel components.

Long-wavelength fiber optic GBICs 100-SM-LC-L. Copper Inter-Enclosure GBIC (Active) 100-TW-EL-S or 100-TP-EL-S with

either DB-9 or HSSDC connectors. Copper Intra-Enclosure GBIC (Passive) 100-TW-EL-S or 100-TP-EL-S

with either DB-9 or HSSDC connectors.

Certified GBICs may be populated in any combination that suits your use. They are “hot-pluggable” and you may snap them in/out without tools.

Refer to the Reference Information appendix for certified GBICs and their specifications. Refer also to the Removal Replacement section of this manual for more information. Figure 1-3 shows a typical GBIC. This one supports fiber optic interconnection media.

General Description

Front Panel Controls

Power Button

Figure 1-2 shows the location of the Power Button. The Power Button is protected by a clear plastic cover that must be flipped UP in order to reach the button. The Power button is an alternate-action switch (press it to turn it on and it stays depressed, press it again to turn it off and the button releases).

When you press the Power button and turn it ON, you enable the logic voltages to leave the Power Supply(s) and enter the Switch logic. The Logic Power Good LED on the front of the chassis and the Power Good light on the back of the Power Supply(s) will light to indicate that the Switch logic is receiving power within the proper voltage range. Refer to the Front Panel LEDs for more information.

As long as the chassis is connected to AC power, the fan(s) run and the power supply(s) produce the logic voltages (3.3 volts and 5 volts) required by the Switch. As long as the Power button has not been depressed (still in the OFF (out) position) the logic voltages do not leave the Power Supply, the Power Good LED on the Power Supply(s) is not lit, and the Logic Power Good LED on the front of the chassis is not lit.

Continuous Test Button

The Continuous Test button on the front panel is an alternate-action switch (press it and it stays depressed, press it again and the button releases). This button must be in the depressed (OP) position for normal operation. The Continuous Test button initiates internal diagnostics when it is in the out (TST) position.

Figure 1-2 shows the location of the Continuous Test Button. The Troubleshooting section in this manual describes the tests and the LED error blink patterns that visually indicate the test failures.

Front Panel LEDs

Refer to Figure 1-2. LEDs visible through lenses in the front of the chassis indicate chassis and port status. During a Reset operation (for about two seconds at the beginning of power-up or as long as the Reset button is pressed) all LEDs are forced ON. The following definitions are valid following the Power-On-

Self-Test (POST) and with the Continuous Test button in the OFF (IN) position. Refer to Section 3 (Diagnostics/Troubleshooting) for information about

POST, LED definitions during Continuous Test, and how the LEDs act when the control code (located in Flash memory) hangs up.

Heartbeat LED (Yellow)

The Heartbeat LED indicates the status of the internal Switch processor, the results of Power-On-Self-Tests (POSTs) run at power-up, and tests initiated by the Continuous Test button.

GigWorks MKII-16 Switch Model MKII-BASE16 Installer's/User's Manual 59003-01 Rev. A

General Description 1-9

General Description

Following a normal power-up with the Continuous Test button in the OFF position, the Heartbeat LED blinks about once per second to indicate that the Switch passed the POSTs and the internal Switch processor is running.

Refer to Section 3 (Diagnostics/Troubleshooting) for more information about Heartbeat LED error codes.

Logic Power Good (Green)

This LED is ON when any Power Supply is delivering power within normal limits to the Switch logic (the Power Button must also be depressed). If you have redundant power supplies, the Logic Power Good LED will stay ON even when one power supply stops working and the other picks up the load. The LED will go OFF when no supply is delivering the proper logic voltages.

Power Supply Fail LED (RED)

This LED is normally OFF. It comes ON only when one supply in a redundant configuration fails but the other supply has picked up the load. When this LED is ON, it is a signal to look at the Power Supply LEDs on the back of each Power Supply to determine which supply failed. Refer to Figure 1-4 for the location of the power supplies and their LEDs. This LED is not meaningful in a system with only one Power Supply.

Over Temperature LED (Red)

Not used. OFF.

Port Logged-In LED (Green)

Each port has its own Logged-In LED. Initially (immediately after the Switch successfully completes the POST, the

Switch holds all Port Logged-In LEDs OFF (no light). They each remain OFF until their connected Fibre Channel Node Port (N_Port) or Node Loop Port (NL_Port) is able to successfully perform a Fibre Channel Fabric Login. The attached node initiates the login process. Following a successful login on a particular port, the Switch turns the Port Logged-In LED ON (lit) for that port. This shows that the port is properly connected and able to communicate with its attached device. The LED for this port remains ON as long the port is still logged in.

If the established link is broken (a fiber opens or the connected port goes out of service), the Port Logged-In LED is shut OFF and the N or NL_Port device will try to regain its logged in status. If the login is once again established, the Switch turns the Port Logged-In LED back ON and communication continues.

Because the attached nodes initiate the Fibre Channel Login process it is important to have the Switch operating before the attached nodes are powered up. Some nodes only try to perform a Fibre Channel Login one

time or several times over a short period of time when they are powered up. If the Switch was not operable at that time, it would miss this login attempt and the attached node may give up trying and require rebooting after the Switch becomes operable.

Port Activity LED (Yellow)

Each port has its own Port Activity LED. The Port Activity LED for a particular port is ON when Class 1, 2, or 3 frames are entering or leaving the port. The Switch turns the LED ON for 50 msec. for each frame, so you should be able to see it for one frame. This LED will not light for frames following an arbitrated loop in bypass mode.

General Description 1-11

General Description

An Input Fuse Holder is incorporated into the AC Input Power Connector assembly. It holds two input fuses. Refer to Section 3 for Troubleshooting information, Section 4 for Removal Replacement, and the Reference Information appendix for fuse size.

Power Supply(s)

The chassis has bays for two power supplies. When there is only one supply, it can operate from either bay and the unused bay is covered with a plate.

The fan on a Power Supply also furnishes cooling for the Switch chassis. A Power Supply fan draws air from the front of the chassis and expels it from the back of the chassis. One Power Supply with its cooling fan is sufficient to operate the Switch.

When there are two Power Supplies, they each become “hot pluggable”. That is, either supply may be removed while the Switch is operating. As long as one good supply remains in operation, the Switch will operate properly. Refer to Section 3 for troubleshooting procedures and Section 4 for Removal/Replacement procedures.

The Power Supply(s) operate independently of the Power Button on the front of the chassis. The supply(s) fan(s) starts to turn and the supply(s) start to produce logic voltages as soon as the chassis is connected to AC power. These logic voltages may, or may not, be enabled out of the power supply into the Switch logic. That depends on the position of the Power Button on the front of the chassis.

Each Power Supply has two lights that indicate its status. Refer to Figure 1-4 for their location.

Power Good Light (Green)

The Power Good Light is ON when its supply is producing logic voltages within their proper voltage ranges and the Power Button is depressed (ON). The light is Off when its supply is not producing proper logic voltages or the Power Button is out (OFF). The Power Button on the front of the chassis must be in the ON position in order to enable the logic voltages into the Switch logic.

Overheat Light (Red)

The Overheat Light is normally OFF. When the power supply senses an overheat condition (airflow blocked or fan stopped) it turns the Overheat Light On and disables its logic voltages. This will turn its own Power On Light OFF and, if it was the only power supply in the Switch, it would power down the Switch. If there was another power supply installed in the Switch, the Power Supply Fail LED on the Switch’s front panel would turn ON and the Switch would continue to operate with the other power supply.

1-12 General Description

GigWorks MKII-16 Switch Model MKII-BASE16

59003-01 Rev. A Installer's/User's Manual

General Description

When the overheated power supply cools down, the power supply will attempt to place itself back in service. If the cause for the overheating condition is still present, the power supply will eventually overheat again and the shutdown process will repeat. During the periods where both power supplies are operating, the Power Supply Fail LED on the front of the chassis will turn OFF. The Power Supply Fail LED will only be ON when one of the two power supplies is actually failing.

Chassis Switch Panel

Refer to Figure 1-4 for the location of the Chassis Switch Panel. The Chassis Switch panel contains a microprocessor Reset button, switches for bypassing the Flash memory and Watchdog Timer, and Test Mode select switches. Use these switches only under the direction of Ancor Customer Service. Refer to the Chassis Switch Panel appendix for a description of these switches and buttons.

Switch Management Connector

The Switch Management Connector is an Ethernet 10BASE-T interface that provides a connection to a management station. The management station, running the Ancor Switch Utilities or SNMP, provides a means to access such things as the Fibre Channel Management Information Base (MIB) and upgrade the control firmware held in the Switch’s Flash memory.

Refer to the Switch Management Section of this manual for information about how to connect the management station and manage the Switch.

Section 2 Installation

Installation

There are seven basic steps required to install the Switch.

1. Unpack

2. Place or Mount the Equipment

3. Apply the IEC Laser Safety Label (If the installation is in Europe)

4. Install the GBICs

5. Connect the Switch to AC power

6. Check the Power-On-Self-Test (POST) results

7. Cable Adapters to the Switch

1. Unpack

a. Unpack the Switch from the carton. There are no packing materials or

shipping fixtures located inside the chassis.

b. Ensure that the power cable has a plug that is suitable for your location.

Ancor supplies the Switch with a standard 3-wire computer-type power cable. One end has an IEC 320 plug that mates with the power connector on the back of the chassis. The other end must have a plug that is suitable for your location. If the power cable has the wrong connection for your location, you must supply your own. Refer to the specifications on page 2-6.

c. GBICs (if you have ordered them from Ancor) are packaged separately.

Ancor supplies one Loopback Plug for each type of GBIC you ordered. A Loopback plug is a plug that, when fully inserted into a GBIC port, interconnects transmit and receive for that port. In case of a suspected GBIC failure, you may use these Loopback Plugs, in conjunction with a test, to verify the operation of a GBIC. Refer to Continuous Test in the Power-OnSelf-Test descriptions in the Troubleshooting section of this manual for more information.

Note:

This manual covers the installation and cabling of single-stage Switch chassis only.

2. Place or Mount the Equipment

The Switch may be placed on a flat surface and stacked or mounted in a 19” EIA rack. The Switch comes physically configured for placing on a flat surface. That is, it comes with rubber feet on the bottom and side-fillers installed. Refer to Figure 2-1.

Figure 2-1 GigWorks MKII-16 Switch Model MKII-BASE16 Chassis Components

Shelf Mount

If you are not going to rack-mount the Switch, simply place it on a flat surface being careful not to obstruct the airflow through the chassis (Allow 165mm (6.5”) front and back. The airflow enters the front of the chassis and exits the back. The top of each chassis has dimples for the rubber feet of a chassis stacked on top.

Rack Mount

If you mount the Switch in a rack, you must remove the side-fillers and install the rack-mounting brackets supplied with the Switch. You may also need to remove the Switch’s rubber feet. They are easily removable in case they are not compatible with your rack. Without the rubber feet, the Switch occupies 2U of space in an EIA rack. The following steps describe how to prepare the chassis for rack mounting:

a. Remove the Face-plate by pulling it straight off the front of the chassis. b. Remove the two Side-Fillers. They are each secured with six captive

c. Mount the Brackets. Refer to Figure 2-2. The Switch is shipped with a

package containing cabinet mounting brackets and screws. You may mount these brackets on the front corners of the chassis or the back corners depending on whether you want the Switch facing the back or front of the cabinet.

d. Place the Switch in a 19” EIA rack and secure it with four (4) 10-32

machine screws (not supplied). The Switch must be supported in the rack on rails or a shelf. If the Switch is supported by a shelf and the vertical space is sufficient, you may leave the rubber feet on the Switch chassis. If the vertical space is not sufficient, you may remove the rubber feet by turning them counterclockwise by hand (or with a flat-blade screwdriver). Be careful not to obstruct the airflow through the chassis (Allow 165mm (6.5”) front and back.

e. Replace the Face-plate if possible. If the Switch is facing the front of the

rack the face-plate should fit. Replace the face-plate by aligning its mounting studs with the appropriate holes in the chassis front and push it straight back.

Do not obstruct the airflow through the chassis. The airflow enters the front of the chassis and exits the back.

3. Apply the IEC Class 1 Laser Information Label (If the installation is in Europe)

If the installation is in Europe, IEC regulations require that a Class 1 laser information label be placed where it is clearly visible whenever access to the optical ports is possible. The drawing below pictures the label.

Remove the paper on the back of the label and apply it to the equipment rack in a place where it is clearly visible whenever access to the optical ports is possible.

4. Install GBICs

You may populate your Switch with 2 to 16 GBICs. The choice of ports and GBICs is yours. The Switch has been validated with GBICs that support a variety of interconnection media.

If you are populating your Switch with 16 GBICs that are all the same media type, install them by following the instructions in the GBIC Replacement procedure in the Removal/Replacement Procedures section of this manual.

If you are installing less than 16 GBICs and/or they are a mix of media types, before you install them, refer to the Tuning paragraphs in Step 7 of this procedure. The Tuning paragraphs give you information that will allow you to use the Switch the most efficiently. Then, install them by following the instructions in the GBIC Replacement procedure in the Removal/Replacement Procedures section of this manual.

Installation

Refer to Appendix A in this manual for Switch power requirements. a. Connect the power cable to the back of the chassis. b. Connect the other end of the power cable to a 3 wire, grounded, AC outlet

that delivers power in accordance with the power requirements specified in Appendix A.

c. Press the Power Button. Refer to Figure 1-2 for its location. The 3-wire grounded power circuit and the 3-wire power cable provide adequate

grounding for the Switch.

Logic Power Good LED

The Logic Power Good LED on the front of the chassis will light when the internal power supply is supplying DC power within its normal operating limits and the Power Button is depressed. Refer to Figure 1-2 for the location of the LED.

If the Logic Power Good LED fails to light when the Power Button is depressed, ensure that both ends of the power cord are properly plugged in, the AC power source is turned ON, and that the input fuses are good.

If you have checked these things and the Power Good LED still is not lit, contact Ancor Customer Service or your authorized maintenance provider. Do not proceed to Step 6 unless the Power Good LED is lit.

6. Check the Power-On-Self-Test (POST) Results

When the Power Supply applies DC power to the Switch logic, the logic runs a Power-On-Self-Test (POST) diagnostic. POST tests the condition of firmware, memories, data-paths, and Switch logic and uses the Heartbeat LED to indicate pass or fail conditions. Refer to the Power On Self Test paragraphs in the Diagnostics and Troubleshooting section (Section 3) of this manual for a description of POST.

About three seconds after the Power Good LED comes on, POST will be complete. At this point the Heartbeat LED will start to indicate whether or not there is a POST error. Check the Heartbeat LED. Figure 1-2 shows the location of the Heartbeat LED.

If the Heartbeat LED is blinking about once every second, the POST passed and you may go to the next step.

If the Heartbeat LED is not blinking once every second, the POST failed. Note what the Heartbeat LED is indicating (by the flash pattern) and contact Ancor Customer Service or your authorized maintenance provider. Do not proceed to

Note:

Following the connection of AC power to the chassis, the fans start turning immediately but power is not applied to the logic until the Power button is pressed.

Step 7 unless the POST passed.

7. Cable N or NL_Port Adapters to the Switch

Ports

All 16 ports on the Switch may connect to N_Ports. Ports 1, 2, 5, 6, 9, 10, 13, and 14 may connect to NL_Ports or N_Ports. The type of media used (fiber optic cable or copper) depends on the type of N or NL_Port adapters used and the type of GBICs used in the Switch. You may populate the Switch with any assortment of approved GBICs appropriate for your interconnection media type.

Tuning

You can optimize the system performance by connecting nodes which interchange the greatest amount of traffic to ports on the Switch which are more efficiently interconnected.

Connect nodes which interchange the least amount of traffic to ports on the Switch which are less efficiently interconnected.

The most efficient performance is within a group of four ports. These groups are:

Ports 1-4 Ports 5-8 Ports 9-12 Ports 13-16

When a frame source-port and destination-port are within the same port group, you will realize:

The lowest Class 2/Class 3 frame latency The highest Class 2/Class 3 point-to-point bandwidth The highest Class 2/Class 3 aggregate bandwidth The lowest Class 1 connect and disconnect latency — Class 1 frame

latency, point-to-point bandwidth, and aggregate bandwidth are not affected by port groups, and are always the theoretical maximum.

When a frame source-port and destination-port are not within the same port group the interconnection is slightly less efficient.

Distance

The maximum distance between each adapter and the Switch depends on the type of GBICs and the type of cable installed. Refer to the Reference Information in Appendix A of this manual for this information. Also, the speed and Fibre Channel Revision Level of each adapter must be compatible with the Switch and the type of I/O media of each adapter must be compatible with the particular GBIC on the Switch.

Hot-Pluggable

All GBICs and cables are “hot-pluggable”. That is, you may have the Switch powered-up while you plug or unplug GBICs or cables of any interconnection media type. Hot-swapping and unplugging does not affect other operating ports.

Incorrect Cabling

Cabling connected incorrectly will not damage the GBICs or the Switch.

N_Port Connections

Connect Fiber Channel N_Ports to F_Ports on the Switch. All 16 ports on the Switch will function as F_Ports. The Switch will automatically discover which N_Port is connected to which F_Port during Fibre Channel Login process as each N_Port is powered up.

Fiber Optic Connections

Note in Figure 2-3 that each N_Port connects to the switch with a pair of connectors. Connect the transmit connector on the N_Port to the receive connector on the assigned F_Port. Connect the receive connector on the N_Port to the transmit connector on the assigned F_Port.

Keys on “Duplex” cable assemblies (a connector-pair containing both transmit and receive fastened together in one unit), prevent you from connecting them incorrectly.

On the F_Port end of the connection, on the top row of F_Ports, the transmit connector is the right-hand connector of each pair. On the bottom row of F_Ports, the transmit connector is the left-hand connector of each pair.

Copper Connections

HSSDC connectors are duplex cable assemblies. That is, both the transmit and receive contacts are part of the same keyed plug assembly. You can’t plug them in wrong.

NL_Port Connections

Ports 1, 2, 5, 6, 9, 10, 13, and 14 on the Switch will function as FL_Ports if connected to NL_Ports. The Switch will automatically discover which NL_Port(s) are connected to which FL_Port during Fibre Channel Login process as each N_Port is powered up.

The Switch FL_Ports support Loop devices running Fibre Channel Public Loop mode. Refer to the Fibre Channel FC-FLA specification.

Fiber Optic Connections

Keys on “Duplex” cable assemblies (a connector-pair containing both transmit and receive fastened together in one unit), prevent you from connecting them incorrectly.

On the FL_Port end of the connection, on the top row of FL_Ports, the transmit connector is the right-hand connector of each pair. On the bottom row of FL_Ports, the transmit connector is the left-hand connector of each pair.

On the NL_Port end, you will have to consult the appropriate adapter or device manual to determine which is which.

Installation

Most NL_Port connections to the Switch are via Hubs or directly to storage devices such as JBODs and disc arrays. Connect the transmit SC fiber optic connector on the FL_Port to the receive SC fiber optic connector on the NL_Port. Connect the receive SC fiber optic connector on the FL_Port to the transmit SC fiber optic connector on the NL_Port.

In some cases you may need to connect a loop of NL_Ports to the Switch without the use of a Hub. Note in Figure 2-3 that these NL_Ports are connected in a loop from the transmit side of an FL_Port on the Switch, through each NL_Port in the loop, then back to the receive side of the original FL_Port on the Switch. Connect the transmit connector on an FL_Port to the receive connector on the first NL_Port in the loop. Continue to connect each NL_Port in the loop, transmit to receive. Then connect the transmit connector on the last NL_Port in the loop to the receive connector of the same FL_Port on the Switch that you connected to the first NL_Port in the loop.

Copper Connections

HSSDC connectors are duplex cable assemblies. That is, both the transmit and receive contacts are part of the same keyed plug assembly. You can’t plug them in wrong. Connect one end of the cable to the Loop device and the other end to a port on the FL_Ports on the Switch.

If Hard Zones are enabled, Name Server Zones may not cross the defined Hard Zone boundaries.

Trivial File T ransfer Protocol (TFTP)

TFTP allows you to:

• load new Switch firmware (8 and 16-port Switches)

• load new management control firmware into the 16-port Switch. (not necessary for the 8-port Switch)

• retrieve and modify the current management configuration of the Switch management processes, including the IP network configuration parameters, and the SNMP configuration parameters.

Simple Network Management Protocol (SNMP)

SNMP allows you to manage the Switch using Simple Network Management Protocol (SNMP) as the transport protocol.

Note:

Before you use any of the management interfaces you must:

• connect the Switch’s Ethernet interface to an Ethernet network and

• configure its IP network address, its IP subnetwork mask, and its IP gateway address. You may configure these IP parameters using either the Switch Utilities or TFTP.

Refer to the Ethernet Cabling and Configuring the Switch Ethernet Port paragraphs in this section.

Switch Management 3-5

Configuring the Switch Ethernet Port

Before the Switch can be managed using the Ethernet port, several management parameters must be set correctly. At a minimum, the IP network address, the IP subnetwork mask, and the IP gateway address must all be set. In addition, the SNMP read, write, and trap community names may be set, as well as the SNMP name, contact, and location. When managing a multi-chassis fabric with the Switch Utilities, this setup is required for each chassis in the fabric. If you are managing the multi-chassis fabric with the Web-based Switch management application, this setup is required only for the chassis that is directly connected to the Ethernet network.

To configure the Switch management parameters, install the Switch temporarily on an isolated network with the subnet address 10.x.x.x (By default, the

Switch’s IP address is 10.0.0.1.). This network does not need to contain anything more than the Switch and a single management host to configure the Switch. You may then use either the Switch Utilities, the Web-Based Switch management application, or TFTP to configure the Switch chassis’ Ethernet port.

Configuring the Ethernet Port Using the Switch Utilities

1. Connect the PC running the Switch Utilities, as per Figure 3-1. You may connect the PC directly to the Switch or through a network. The Switch is configured at the factory to use the IP address 10.0.0.1 and network mask

255.0.0.0. The PC must also be configured to use an address in the range

10.0.0.2 to 10.255.255.254, and to use the same network mask 255.0.0.0.

2. Follow the Loading the Switch Utilities and Getting Started paragraphs in Managing the Switch Using the GigWorks MKII Switch Utilities to load and start the Switch Utilities on the management station.

3. In the Setup Tab of the Switch Utilities, select Switch IP Address 10.0.0.1. This allows you to communicate with the Switch chassis with its default IP Address.

4. In the Management Configuration Tab, set the appropriate values for the Network IP Address, Broadcast IP Address, Network Mask, and Gateway

Note:

The Switch cannot be managed through the Ethernet port without the management station knowing the IP address of the Switch. If the IP configuration of the Switch is lost, the Switch can be reset in PROM mode. In

Prom mode, the Switch always uses the default management parameters, not the parameters defined in the configuration file. In this way, the

Switch can always be returned to a 10.0.0.x network and reconfigured. Contact Ancor Customer Service for instructions on how to place your Switch chassis into Prom mode.

IP Address. When all parameters have been set correctly, click the Set Parameters Button to set the values on the Switch chassis. The new values will be saved on the Switch, and will take effect when the Switch is powered down and back up (re-booted). You may also force the Switch to begin using the new values immediately by clicking the Reset the Ancor GigWorks MKII Management Only Button. Remember to write down the

new IP Address so you can use it to access this Switch when it is rebooted.

Configuring Multiple Switches

If you are performing an initial configuration on multiple Switches, you must not connect the PC to more than one Switch at a time, since all Switches will initially be using the same IP Address 10.0.0.1. To configure more than one Switch, connect the PC to a single Switch at first, change its IP network parameters, and when completed, connect the PC to the next Switch to be configured. When you connect the PC to the next Switch,

remember to flush the ARP cache on the PC, since the Switch Ethernet address will have changed, while the IP Address will still be the same

10.0.0.1. A typical command for doing this is: arp -d

10.0.0.1.

You are now ready to use the Switch Utilities. Paragraphs under the Using the Switch Utilities will describe each Tab and supporting menus such as File, View,

and Help.

Configuring the Ethernet Port Using TFTP

To configure the Switch chassis:

1. Connect to the Switch using TFTP. This is a standard utility included in most Unix and Windows NT workstations. Versions for other platforms can be obtained from other vendors.

Because TFTP has no passwords, user authentication, or other security, only trusted users should have access to the Switch through the Ethernet port.

2. Select text file transfer mode.

3. Retrieve the Switch configuration file named config.

4. Use any text editor to modify the parameters of this configuration file.

5. Transfer the configuration file back to the Switch file config.

6. The Switch can now be powered down and moved to the production network. When the Switch is powered up, it will execute with the new parameter values defined in the configuration file.

Refer to the Managing the Switch Using TFTP paragraphs later in this section for more detail.

Loading the Switch Utilities

In order to run the Switch Utilities, you must provide an IBM®, or compatible, PC with an Ethernet output, running Windows NT™ version 4.0 or Windows 95™ (or later), and an Ethernet cable. You will use the cable to connect the PC to the Switch Management Connector of the Switch. Instructions for the PC installation and Switch Utilities operation follow.

1. Set the Power Switch on the PC to ON.

2 Boot the PC with Windows NT Version 4.0 or Windows 95 or later.

3. Use the following steps to Load the Switch Utilities software. Ancor supplies the Switch Utilities software on two floppy diskettes.

Loading the Switch Utilities Software into a PC from Floppy Diskettes

a. Insert the Ancor MKII Switch Utilities - Disk 1 floppy into the floppy

drive.

b. Choose Run on the Start menu. The screen will display the Run dialog

box.

c. Enter: X:setup (where X is the drive letter of

the floppy drive) and press Enter.

Follow the prompts. The system will prompt you for the second disk.

When the Switch Utilities are loaded, remove the second floppy and proceed to the Getting Started paragraphs.

Getting Started

After you have completed the PC Installation, including the loading of the Switch Utilities software, use the following steps to start the Switch Utilities .

1. From the Start menu choose Program>Ancor>GigWorks MKII Switch Utilities. The screen will display the application window with the Setup tab selected.

The Setup tab is the first tab displayed in a set of tabs that allows various operations on the Switch. All the tabs are described in the Using the Switch Utilities paragraphs but first you must use the Ethernet Port Radio Button in the Setup tab for some basic setup.

2 In the Setup Tab, make sure the Ethernet Port Radio Button is selected, and

set the IP Address field to the IP address of the switch to be managed. (All

3. Use the Setup Tab to read the UART statistics to make sure the Utilities can connect to the Switch.

Using the Switch Utilities

The user interface to the Switch Utilities is a standard Windows™-type interface structured like a set of tabbed file folders (Refer to Figure 3-2). Use the cursor to click on any tab and the screen will display a dialog box for that tab. The dialog box for the Setup tab is always the first that the system opens when entering the Switch Utilities.

Each tab is supported by the File and Help menus. These paragraphs assume that you understand standard Windows interface

practices (for example, how to control the cursor, use the keyboard, and how to save files etc.).

File

File>Open

The Open command operates on the Flash tab only. The Open command prompts you to select the file containing the new Switch control code to be loaded into Flash memory.

File>Save

The Save command operates on a tab-by-tab basis. That is, if you perform a Save command while the Setup tab is selected, the system saves the contents of the data window of only the Setup tab. The first time you perform a Save for a particular tab, the system treats it like a Save As command and prompts you to name the file and indicate the location where you want the file to be saved. This file name/location becomes the default for that tab. The second and subsequent times you perform a Save command for that tab, the system appends the new data to the content of the old file. If you perform a Save As command for that same tab, you change the default file/location for the selected tab. The Switch Utilities will remember these default file names/locations for each tab from session to session.

You may use the same file name/location for each tab or have a different one for

Refer to Figure 3-3. The Flash tab enables you to load new control code into the Switch’s Flash memory and also to command the Switch to perform a Reset operation.

In order to load new Flash Code, you must first connect the switch directly to the PC used as a management Station using a “Cross-Over” Cable.

In the event that your Flash memory requires an update, Ancor Communications will supply you with a binary Flash update file. This file may be available on a floppy, CD-ROM, or it may be available over the Internet. In any case, load this file on the PC (the one connected to the Switch’s Ethernet port) and select the Flash tab in the Switch Utilities.

You may load new Flash code to the Switch’s Flash memory while the Switch is operating under the old Flash code. The Switch will not use the new Flash code until it is Reset. The Switch will Reset when you command a Reset operation from the Switch Utilities Flash tab or you cycle the Power on the Switch.

Switch Utilities — Diagnostics Trace

Diagnostics Trace

Diagnostics Trace Overview

The Diagnostics Trace tab allows Ancor service personnel to follow the progress of selected operations as they proceed through the Switch. This tab is included in the Switch Utilities for the customer because at some point, if you are experiencing problems, an Ancor Service engineer may ask you to perform a Diagnostics Trace, read the results, and send them back to the factory. Therefore, use this tab only under the direction of Ancor Customer Service personnel.

A typical Diagnostics Trace scenario follows (Refer to Figure 3-5):

1. Press the Enables radio button to enable the Enables display and controls.

2. Use the Enables controls to read the current list of Diagnostics Trace functions from the Switch.

3. Press the Trace Clear button to clear the Switch’s Diagnostics Buffer.

4. Use the Enables controls to select (highlight) one or more of the Diagnostics Trace functions. Selecting a time stamp is optional (in the list of functions).

5. Use the Enables controls to apply the selected Diagnostics Trace functions to the Switch. This clears the Diagnostics Trace buffer (if you had it selected in the list of functions) and activates the selected Diagnostics Trace operations in the Switch. At this point the Switch is logging the progress of the enabled Diagnostics Trace functions into the Diagnostics Trace Buffer.

The Ancor service engineer may have you perform a specific operation like attempt a login from a node connected to the Switch or communicate between devices interconnected through the Switch.

Switch Utilities — Port Status

Port Field: The Port field lists each port on the Switch. Status Field: The Status field tells whether a port is Online or Offline. Mode Field: The Mode field tells whether a port is operating as an F_Port, an

FL_Port, or a T_Port (Trunk Port in a multi-stage fabric). Login Status Field: The Login Status field indicates whether or not a port is

Logged in. AL-Enabled Field: The AL-Enabled field is user controlled. If the AL-Enabled field for a particular port is labeled Yes, the port is allowed to

“self discover” its mode by determining the type of node port it is connected to. If it is connected to an N_Port, the Switch port will operate as an F_Port. If it is connected to an NL_Port, the Switch port will operate as an FL_Port.

If the AL-Enabled field for a particular port is labeled No, the port is forced to an F_Port. Thus, if you have a single loop device (NL_Port) that is able operate with either an FL_Port or an F_Port you have the option to force it to operate on an F_Port.

If the field for a particular port is labeled N/A, the port can only be an F_Port. The default for all ports on an 8-port Switch or half of the ports on a 16-port

Switch is Yes. If you want to toggle the enable for a particular port to No, select (highlight) the port and click the Toggle AL-Enabled button. The attached device is forced Offline and must re-establish port login with the Switch. The NL_Port must be able to operate with an F_Port in order to re-establish Online Status.

Toggle AL-Enabled Button: This button toggles the AL-Enabled field for the selected port. If the selected port is an FL_Port, toggling the AL-Enabled field to No will immediately force the attached node Offline. The attached node must be able to log in and operate on an F_Port.

Save Changes Button: If you don’t save the changes, the next time the Switch initializes, it will use the previous AL-Enable settings. Click the Save Changes button to use the changes permanently.

Refresh Button: Refreshes the information in the Port Status window and Loop Devices window if an FL_Port is highlighted.

Loop Devices Window

The Loop Devices Window contains three fields, AL_PA, Status, and LoginStatus and four control buttons, Reset & Reinitialize Loop, Reinitialize Loop, Enable all on Loop, and Toggle Bypass/Enable.

When you first open the Port Status tab the Loop Devices window is blank. Select (highlight) an FL_Port in the Port Status window and the Utilities application will poll the Switch to get the loop information. If the selected port is an F_Port, the Loop Devices window is blank.

depends on the capabilities of the loop devices and what has happened since the loop was last initialized.

Generally, when a loop is initialized, all Enabled devices that successfully initialize receive an AL_PA. Thus the Switch knows of their existence and can report that fact to the Switch Utilities. There may be devices on the loop that are not powered up or are in Bypass mode. These devices will not receive AL-PAs and the Switch will not know of their existence. Therefore, the Switch will not report on them to the Switch Utilities.

The Switch Utilities give you the ability (if the particular device has the ability) to control the mode of the loop device. That is, you may Enable the device or place it in Bypass Mode. If the device had received an AL_PA before it was placed in Bypass Mode, the Switch still knows about it and can report on it to the Switch Utilities. If you change the mode of a particular device from Enabled to Bypass, the Switch Utilities will still know about the device. But if you then reinitialize the loop, that device (now in Bypass Mode) will not receive an AL_PA and the Switch/Utilities will no longer know about it.

AL_PA Field: This field contains the AP_PA of the loop device. Status Field: This field contains the current mode of the loop device (Enabled or

Bypass) and, if the device permits, is controllable through the Switch Utilities. To toggle the mode, select (highlight) the device entry in the Loop Device window and press the Toggle Bypass/Enable Button.

Toggle Bypass/Enable Button: Press this button to toggle the mode of the selected device. Remember that if you place a device in Bypass mode and then re-initialize the loop, the device will lose its AL_PA.

Reset & Re-Initialize Loop Button: Press this button to both Reset and reinitialize the loop. Remember that devices that you placed in Bypass mode will not receive an AL_PA and will disappear from the window when you click the Refresh button.

Re-Initialize Loop Button: Press this button to re-initialize the loop. Remember that devices that you placed in Bypass mode will not receive an AL_PA and will disappear from the window when you click the Refresh button.

Enable all on Loop Button: Press this button to enable all the devices on the loop that can be enabled. Click the Refresh Button to receive new status.

Switch Utilities — Zoning

Zoning

Figure 3-10 Zoning Tab

Zoning allows the user to divide the fabric ports into zones for more efficient and secure communication among functionally grouped nodes. There are three types of zones and a port may be defined in any or all of them.

• Broadcast Zones allow the division of the fabric (one or more Switch chassis) into as many as 16 zones (the Switch Utilities only support 4 zones at this time but each zone is fabric-wide) that define the area of Broadcasts. A particular port may be placed in one or more of these Broadcast Zones. A port will broadcast to all ports in the same Broadcast Zone (or zones) in-which the port is defined. If Hard Zones are enabled, Broadcast Zones may not cross the defined Hard Zone boundaries.

• Name Server Zones allow the division of the fabric (one or more Switch chassis) into as many as 16 zones (the Switch Utilities only support 4 zones at this time but

each zone is fabric-wide) that define which ports receive Name Server information. A particular port may be defined in one or more of these Name Server Zones. A port will receive Name Server information for all ports in the same Name Server Zone (or zones) in-which the port is defined. If Hard Zones are enabled, Name Server Zones may not cross the defined Hard Zone boundaries.

Hard Zone Rules:

1. A Hard Zone is only valid if it is enabled.

2. Hard Zones apply only to single stage switch fabrics (one chassis).

3. There is a maximum of four Hard Zones (8-port or 16-port switch).

The Utilities number them 1 through 4.

4. All ports in a physical group must be in the same Hard Zone. Rule 7 defines Physical groups.

5. Hard Zones may include multiple physical groups. Rule 7 defines Physical groups.

6. An individual port can only be in one Hard Zone.

7. Hard Zones must follow physical group-boundaries.

The following port-groups define the boundaries for an 8-port Switch: 1,2 3,4 5,6 7,8 The following port-groups define the boundaries for a 16-port Switch: 1,2,3,4 5,6,7,8 9,10,11,12 13,14,15,16

8-Port Switch Zone examples:

a. Ports 1,2,3, and 4 in one zone, ports 5 and 6 in a second zone, and

ports 7 and 8 in a third zone.

b. Ports 1,2,5,6,7 and 8 in one zone, ports 3 and 4 in a second zone.

16-Port Switch Zone examples:

a. Ports 1, 2, 3,4, 5, 6, 7, and 8 in one zone, ports 9, 10, 11, and 12 in

a second zone, and ports 13, 14, 15, and 16 in a third zone.

b. Ports 1 through 12 in one zone, ports 13 through 16 in a second

zone.

8. If any port on the chassis is defined as being in an enabled Hard Zone, all ports must be defined in enabled Hard Zones (No Hard Zone Orphans). A Hard Zone Orphan is defined as a port not defined in any enabled Hard Zone.

Switch Utilities — Zoning

Broadcast Zone Rules:

1. A Broadcast Zone is only valid if it is enabled

2. If Broadcast Zones are used on a Single Stage Switch in-which Hard Zones are defined, the Broadcast Zones must not overlap Hard Zone boundaries.

For example: If Hard Zoning in an 8-port Single Stage Switch places Port 6 in one zone and Port 7 in another zone, Broadcast Zoning must not include Ports 6 and 7 in the same zone.

3. Broadcast Zones operate fabric-wide (Single Stage or Multi-Stage).

4. There is a maximum of 16 Broadcast Zones (independent of Name Server Zones). The Web-based GUI and Utilities number them 1 through 16.

5. A port may be defined as being in one or more Broadcast Zones (Broadcast Zones may overlap).

6. When a port sends a broadcast, the broadcast goes to all ports in the Broadcast Zone (or zones) that the port is defined in.

7. All ports not defined as being part of any enabled Broadcast Zone are Broadcast Zone Orphans. Broadcast Zone Orphans are all placed in the same Broadcast Orphan zone.

Name Server Zone Rules:

1. A Name Server Zone is only valid if it is enabled.

2. If Name Server Zones are used on a Single Stage Switch in-which Hardware Zones are defined, the Name Server Zones must not overlap Hardware Zone boundaries.

For example: If Hard Zoning in an 8-port Single Stage Switch places Port 6 in one zone and Port 7 in another zone, Name Server Zoning must not include Ports 6 and 7 in the same zone.

3. Name Server Zones operate fabric-wide (Single Stage or Multi-Stage).

4. There is a maximum of 16 Name Server Zones (independent of Broadcast Zones).

The Web-based management application and Utilities number them 1 through 16.

5. A port may be defined as being in one or more Name Server Zones (Name Server Zones may overlap).

5. When a port receives Name Server information, it will receive information about all ports in the Name Server Zone (or zones) that the port is defined in.

Managing the Switch Using TFTP

The firmware in the Switch can be upgraded using the Trivial File Transfer Protocol (TFTP). This is a standard utility included in most Unix and Windows NT workstations. Versions for other platforms can be purchased from other vendors.

Because TFTP has no passwords, user authentication, or other security, only trusted users should have access to the Switch through the Ethernet port.

Retrieving the Current Switch Management Configuration File ( config ):

The Switch file named config contains the current management configuration of the Switch management processes, including the IP network configuration parameters, and the SNMP configuration parameters.

To retrieve the Switch configuration file: 1 Connect to the Switch using TFTP.

2. Select text file transfer mode.

3. Retrieve the file named config.

The actual keystrokes for the above steps varies depending on the operating system of the management station. For example, your TFTP session may look like this if you are using a Unix system as a management station:

#tftp (Start TFTP) tftp>connect 10.0.0.1 (Connect to the Switch. This example uses

the default netAddress for the Switch)

tftp> text (Select text file mode.) text mode tftp> get config (Retrieve the file named config. ) transferred 254 bytes in 0.5 seconds. tftp> quit (Exit TFTP)

#cat config (Look at the contents of the config file.) netAddress=10.0.0.1 netMask=255.0.0.0 broadcast=10.255.255.255

Note:

Before you use TFTP you must connect the Switch’s Ethernet interface to an Ethernet network and configure its IP network address, its IP subnetwork mask, and its IP gateway address. Refer to the Ethernet Cabling and Configuring the Switch Ethernet Port paragraphs in this section.

The Switch contains a file called config which contains the current management configuration of the Switch management processes, including the IP network configuration parameters, and the SNMP configuration parameters.

Use the instructions in the Retrieving the Current Switch Management Configuration File ( config ) paragraphs to read the Switch’s configuration file. Use a text editor to modify the parameters in the configuration file and then transfer it back to the Switch.

To transfer the Switch configuration file to the Switch:

1. Connect to the Switch using TFTP.

2. Select text file transfer mode.

3. Transfer the file named config.

If the file transfer succeeds, the new configuration file has been saved in the management processor, and will be loaded next time the Switch is reset. A reset operation takes place when the Switch power is cycled. You may also reset the Switch using TFTP. This is described later in this section.

For example, your TFTP session may look like this if you are using a Unix management station:

The new management configuration values will not take effect until the Switch is reset. If the Switch’s IP address is changed and then the Switch is reset, it will no longer respond to the previous IP address, but will now respond only to the newly configured IP address.

The Switch Management Configuration File

The parameters of the Switch management configuration file (config ) are: netAddress The IP network address. By default this is 10.0.0.1. netMask The IP subnetwork mask. By default this is 255.0.0.0. broadcast The IP broadcast address. By default this is 10.255.255.255. If

this parameter is omitted from the configuration, the Switch will compute the correct broadcast address from netAddress and netMask.

gateway The IP address of the network gateway. If this parameter is set to

0.0.0.0, the Switch will assume that no gateway is available.

arpTimeout The time in seconds to expire entries in the arp cache. By default

this is set to 30000 (about 8 hours).

snmpReadCommunity

The SNMP community name to be recognized for SNMP Get and GetNext requests. By default this is the string “public”.

snmpWriteCommunity

The SNMP community name to be recognized for SNMP Set requests. By default this is the string “private”.

snmpTrapCommunity

The SNMP community name to be used in SNMP Trap messages. By default this is the string “public”.

snmpName

The value of the SNMP Systems Group SysName variable. This is usually identical to the host name, for example, “switch001”. The default value for this parameter is the empty string, “”.

snmpContact

The value of the SNMP Systems Group SysContact variable. This is usually set to identify the person or organization responsible for maintaining the host, for example, “Joe Cable, x1234”. The

Note:

If any of these management configuration parameters are changed using SNMP after the config file has been written by TFTP, but before the Switch is reset, the SNMP process will save its now-current configuration into the config file, over-writing and deleting the config file sent using TFTP. To avoid this problem, reset the Switch immediately after the TFTP transfer.

Reset the Switch Using TFTP:

Reset the Switch via TFTP by attempting to read or write a file named reset. This is not a valid file name on the Switch, but any request from a TFTP client to store or retrieve a file named reset will cause the Switch to reset itself.

To reset the Switch using TFTP

1. Connect to the Switch using TFTP.

2. Select either binary or text file transfer mode.

3. Attempt either to upload or to download a file named reset.

The Switch will return the error message, “MKII RESET” before resetting. Note: Since resetting the Switch disrupts service on the Fibre Channel ports, this

feature allows a possible denial-of-service attack on the Switch. Only trusted users should have access to the management port on the Switch.

Managing the Switch Using SNMP

Managing the Switch Using the Simple Network Management Protocol (SNMP)

Network management is the process of planning, organizing, and controlling a communications-oriented system. This involves two types of issues: softwarerelated (data security, overseeing applications, user accounts, and permissions) and hardware-related. These paragraphs concentrate primarily on the second issue

-- the management of the network as a whole, using the Simple Network

Management Protocol (SNMP) as the transport protocol. The Switch uses SNMP as the transport protocol. Network Management examines:

• Network Management

• The Network Management Station

• The Switch Node Agent

• The Management Information Bases (MIBs)

• The Simple Network Management Protocol (SNMP)

Network Management

Various forms of network management capabilities have been built into most network hardware pieces which includes workstations, servers, network cards, routers, bridges, hubs, etc. Because these nodes are generally dispersed throughout a network configuration, the administrator relies on the built-in communication functions to remotely query the status of the equipment as well as receive alerts when problems occur. There are two fundamental goals when designing and setting up a network management infrastructure to ensure optimal management. First, management information traffic should not significantly increase overall network traffic. Second, the node agent should not significantly increase the processing overhead (thus, interfering with that node’s primary function).

The basic concept of network management involves a network manager exchanging information with processes (agents) residing within network nodes using SNMP. The network management station communicates with the different management processes to gather data and construct visual representations about the status of the network. The network manager handles the overall network software and inter-node communications. Support software provides a user interface that allows the administrator to observe the condition of the entire system as well as individual components, and monitor any specific node.

Note:

Before you use SNMP you must connect the Switch’s Ethernet interface to an Ethernet network and configure its IP network address, its IP subnetwork mask, and its IP gateway address. Refer to the Ethernet Cabling and Configuring the Switch Ethernet Port paragraphs in this section.

Switch Management 3-49

Managing the Switch Using SNMP

Figure 3-13 illustrates the four main components involved in network management.

Figure 3-13. Network Management Framework

The Network Management Station

A network management station is a centralized node (usually a dedicated workstation) connected to a network that runs some kind of network management software application (manager). For example OpenView™ from Hewlet Packard, NetView™ from IBM, Spectrum™ from Cabletron, or SunNet Manager™ from Sun Microsystems. Generally, the manager supports and uses SNMP to monitor the network and collect information from the agents in the network. The manager, rather than the agents, has the intelligence to use and interpret the information provided by the agents. This information enables the administrator to examine the statistics and monitor the network for performance or operation problems. The network management station provides the following principal functions:

Function Description

Managing Nodes The administrator can manage network nodes,

either remotely or locally, by issuing SNMP commands from the management station and receiving responses to queries. Most management stations provide user-friendly interfaces.

Error Message Clearinghouse The management station receives error messages

from various managed nodes and initiates any necessary pre-programmed actions. A good implementation also retains a database of error messages to provide a history of events for diagnostics or troubleshooting.

Network Mapping The management station displays the network

layout map based on information collected from various agents as well as MIB information in an easy-to-understand manner. It can also show alarm

symbols to alert the administrator to problems.

Statistics Displays Agents provide statistics about the overall

behavior of network components and the station manager displays the information in either numeric or graphical formats.

The Node Agents

The Switch has a built-in SNMP-compliant node agent. A management or node agent is a specific software component that resides on a network node (such as switches, routers, and servers). The agent collects information about that particular node and/or its environment although the agent does not have the intelligence to use the information. When a network node contains an agent, it is referred to as a managed node. If the node is SNMP-compliant or SNMP-manageable, that means the resident agent supports the SNMP protocol for information exchange.

When the agent communicates with the network management station, the following main tasks are performed over this link:

Task Description

Information Provision The node agent provides information about the

network nodes to the management station.

MIB Entry Editing When requested by the network management station, the

node agent updates, adds, or removes entries (such as routing table entries) in the database maintained by the agent.

Error Reporting The node agent reports problems to the management

station and/or responds to the station’s status queries.

The Management Information Bases (MIBs)

A MIB is a database, maintained by a node agent, that contains configuration and statistical data about nodes on a network as well as information pertaining to the performance of the node and its connections to different network nodes. The network manager queries the MIB through either the agent or proxy agent software and can specify changes to the configuration. A MIB describes the objects (or entries) included in the database. Each object has four properties that define what each object looks like. MIB object properties include:

Property Description

Name This property defines the name of the particular object. For example,

sysUpTime. It is simply a label.

Syntax This property specifies the data type such as integer, octet string,

GigWorks MkII-16 Switch Model MKII-BASE16 Installer's/User's Manual 59003-01 Rev. A

Switch Management 3-51

Managing the Switch Using SNMP

object identifier, or NULL. NULLs act as place holders reserved for future use.

Access This property indicates the level of access to this particular object.

Legal values are: read-only, read-write, write-only, and not accessible.

Status This property defines the implementation requirement for this object:

mandatory (the managed node must implement this object); optional (the managed node may implement this object); or obsolete (the managed node need no longer implement this object).

The presence of objects, their names, and additional property values are part of each MIB specification. Currently, there are three types of MIB specifications:

Standard MIBs

The standard MIB contains a set of objects that are well defined, known, and accepted by the Internet standards group. There is a generic MIB defined for managing network nodes. And, there are two versions of this standard MIB called MIB-I and MIB-II. These MIBs contain standard managed objects that are grouped into different functional categories.

Vendors may choose to implement MIB-I or MIB-II for their agents as well as their network management software. That means if you use a MIB-I network management station to query a MIB-II node, you will not get the full range of possible data. Conversely, if you use a MIB-II network management station to query a MIB-I node, many of the data displays on the console will read blank or zero because of the unavailability of the extra objects.

Experimental MIBs

The experimental MIB contain MIBs that are not in the standard MIBs and are not part of the private or enterprise MIBs. These MIBs may contain specific information about other elements of the network and node management. When an experimental MIB is proven effective and refined, it can be considered a standard MIB. Some experimental MIBs include: T1 Carrier Objects, Ethernet-like Objects, Token Ring-like Objects, and FDDI Objects.

The Fibre Channel Fabric MIB, supported by the GigVision Proxy Agents is an Experimental MIB (Refer to Appendix D in this manual). Also, the Fibre Channel Node MIB, supported by the GigVision Sub-agents, is an Experimental MIB (Refer to Appendix C in this manual)

Enterprise MIBs

Enterprise MIBs are designed by individual companies for their own networking nodes. For network management software that is not from the enterprise MIB vendor to read these MIBs, the manager must know the MIB object names to access them. Often the enterprise MIBs from a vendor are product-line or model

specific. The Ancor MKII Accounting MIB is an enterprise MIB.

The Simple Network Management Protocol

SNMP is a well-defined, public standard that is widely used by the Internet community. The SNMP was first developed to address router management issues on the Internet and was designed to be protocol-independent (so it can be used over IP, IPX, AppleTalk, OSI, and other transport protocols as necessary). SNMP is a set of protocols and specifications that provides a means of collecting network management information from nodes on the network. It also provides a means for the nodes to report problems and errors to the network management station.

SNMP was designed to allow network management station software to communicate with agents in the managed nodes. The communication may involve request messages from the management station, response messages from the agents, or error messages (alarms) generated from the agents to the management station. SNMP allows the administrator to remotely query existing variables from an SNMP-compliant node as well as set new values.

Data Collection Methods

There are several processes that network management stations and nodes use to communicate with each other. The procedures allow the management station to systematically request data as well as provide a method for nodes to transmit error messages to alert the management station about network problems. SNMPcompatible network components use the following data collection methods:

Polling-Only Data Collection

This method allows the management station total control of the communications. The management station queries the nodes for statistics and data transmission at regular, user-specified intervals. A disadvantage of this method is timeliness of information, particularly errors. Polling-only requires a regulated interval and node sequence for polls. Short intervals generate excessive, unnecessary traffic and long intervals in the wrong order can result in delayed notification of catastrophic events.

Figure 3-14 illustrates how an SNMP management station polls the managed node for information.

GigWorks MkII-16 Switch Model MKII-BASE16 Installer's/User's Manual 59003-01 Rev. A

Switch Management 3-53

Managing the Switch Using SNMP

Figure 3-14 Polling-Only Data Collection

Interrupt-Based Data Collection

This method provides immediate notification to the network management station if an extraordinary event occurs (assuming the node has not crashed and the communication path between the node and the management station remains intact). A drawback of this method involves the resources required to generate the error (or trap). If the error message contains a lot of information, the managed node expends valuable time and resources generating the error rather than performing its primary function.

Also, if several identical events occur back-to-back, excessive network bandwidth is tied up with repeated information. It would be particularly unfortunate if the errors pertained to network congestion. To avoid this, thresholds can be established for the managed node regarding when to report problems. However, threshold monitoring also requires agent resources to determine the appropriateness of generating a trap.

Figure 3-15 illustrates how a managed node agent interrupts its operation to report errors to the SNMP management station.

Figure 3-15 Interrupt-Based Data Collection

Trap-Directed Polling Data Collection

This method is a combination of the polling-only and interrupt-based data collection processes and is a highly effective and efficient means of performing network management. The management station polls the agents in the managed nodes to collect data and then displays the data on the console in either numeric

or graphical representation allowing the administrator to easily diagnose and manage the nodes and network traffic.

Additionally, agents in the managed nodes can report error conditions (such as when user-set threshold levels have been exceeded) to the network management station without waiting to be polled for the information. Using the combined approach, when a managed node agent generates a trap, the network management station can query the node for additional information.

Figure 3-16 illustrates the interaction between the SNMP management station and managed node agent for information exchange.

Figure 3-16 Trap-Directed Polling Data Collection

Community Types

Each SNMP request is signed with an identifier called an SNMP community name. Although SNMP places no restrictions on the bytes in the community name, the node agent and management station may place specific restrictions on the characters that may be used (such spaces, tabs, open square brackets, equal signs, colons, semicolons, number signs, etc.) or on the length of the string (such as, up to 32 characters). Three types of communities exist and each can have a different name.

Community Type Description

Monitor Community This community name grants read access to SNMP MIBs.

For each SNMP query, the network management station must include the monitor community name in the message. By default, the monitor community name is set to “public.”

Control Community This name grants read and write access to the MIBs.

Because some MIB objects are read-only, even with the correct control community name, a network management station cannot modify the variables contained in the MIB. By default, the control community is disabled so that MIBs are not modified accidentally.

File Name Location and Description

get-request / get-response Used to retrieve a single object in the MIB or query a

MIB; a get-request message receives a get-response message.

• interface — MIB II Interfaces Group

• snmp — MIB II SNMP Group

• fcFeConfig — Configuration

• fcFeOp — Operation

• fcFeError — Error

• anMkiiAccounting — Accounting

• fcFeCap — Capabilities

• anMKiiUtility — MKII Utility MIB

Each group has one or more tables associated with it. The Switch does not support the Accounting Group of the draft standard Fibre

Channel MIB. Instead, it supports the Ancor enterprise accounting MIB anMKIIAccounting .

The Fibre Channel Fabric Element MIB defines the fcFeConfig, fcFeOp, fcFeError, and fcFeCap groups. The Ancor MKII Accounting MIB defines the anMkiiAccounting group. The Ancor Utilities MIB defines the Ancor-specific configuration and parameters.

All MIBs are available on the Internet through the Ancor Customer Services link in the Ancor Web-site (www.Ancor.com).

MIB II (RFC 1213) Groups

• system — high-level host information

• interface — configuration information, and traffic and error statistics for the Ethernet interface

• SNMP — configuration information, and traffic and error statistics for the SNMP agent

Configuration Group Tables

• fcFabricName — Fabric Name — a universally unique name for the Fibre Channel Fabric, including all nodes and switch elements

• fcElementName — Element Name — a fabric-unique name for this switch element

• fcFeModuleCapacity — Module Capacity — the number of modules in this

switch element

• fcFeModuleTable — Module Table — a table of information about each module in the switch element

• fcFPortConfigTable — Port Configuration Table — a table of the current configuration parameters for each port in the switch element

Operation Group Tables

• fcFPortOperTable — F_Port Operations Table — a table of the operational values of each port in the switch element

• fcFPortFlogiTable — F_Port Login Table — a table of the service parameters defined during the last login

• fcFPortPhysTable — F_Port Physical Level Table — a table giving the physical status of each port in the switch element

Error Group Tables

• fcFPortErrorTable — F_Port Error Table — a table of error counts for each port in the switch element

Account Group Table

• anMkiiAccounting — a table of traffic statistics for each Fibre Channel port

Capability Group Tables

• fcFPortCapTable — Port Capabilities Table — a table of configuration parameters supported by each port in the switch element

MKII Utility MIB

• anMKiiUtility — an Ancor enterprise-specific MIB for MKII Switch management Functions

Configuring SNMP

The Switch management configuration file defines the following SNMP parameters:

snmpReadCommunity The SNMP community name to be recognized for

SNMP Get and GetNext requests. By default this is the string “public”.

snmpWriteCommunityThe SNMP community name to be recognized for

SNMP Set requests. By default this is the string “private”.

snmpTrapCommunity The SNMP community name to be used in SNMP

Trap messages. By default this is the string “public”.

snmpName The value of the SNMP Systems Group SysName variable. This is

usually identical to the host name, for example, “switch001”. The default value for this parameter is the empty string, “”.

snmpContact The value of the SNMP Systems Group SysContact variable.

This is usually set to identify the person or organization responsible for maintaining the host, for example, “Joe Cable, x1234”. The default value for this parameter is the empty string, “”.

snmpLocation The value of the SNMP Systems Group SysName variable. This

is usually set to identify the physical location of the Switch, for example, “Wiring Closet B, 3rd floor, East”. The default value for this parameter is the empty string, “”.

snmpDoAuthTrap Whether the Switch SNMP agent should send SNMP

authentication traps. By default, traps are not sent.

snmpTrapAddress The IP address of the management station to which SNMP

traps should be sent. By default, this is the localhost address,

127.0.0.1.

The Switch management configuration file can be retrieved using TFTP, modified using any text editor, and stored using TFTP onto the switch again. (See Managing the Switch Using TFTP in this section for more information)

The MIB II Systems Group objects, sysName , sysContact , and sysLocation can also be modified using SNMP.

Diagnostics/Troubleshooting 4-1

Section 4 Diagnostics/Troubleshooting

Introduction

Section 4 contains information to help you find problems. Power Supply Troubleshooting helps you solve AC power and Power Supply

problems. Power-On-Self-Test (POST) checks the condition of Switch with the exception of the

GBICs. Continuous Test checks the condition of the Switch including the GBICs and

requires that you place a Loopback plug on each GBIC. Fiber Continuity tests for open fibers in the cable network.

Power Supply Troubleshooting

Tables 4-1 and 4-2 are troubleshooting matrixes for finding AC source power and Power Supply problems. They use indications such as LEDs and fan rotation to find problems. Use Table 4-1 for chassis that contain one Power Supply. Use Table 4-2 for chassis that contain two Power Supplies.

If the appropriate table does not lead you to the problem or if you need a new Power Supply, notify Ancor Customer Service or your authorized maintenance provider. Refer to Appendix B for information about how to contact Ancor Customer Service.
