CHAPTER 1 Introduction

About This Guide

This guide is designed to provide the user with the necessary information to install the Vixel Model 335 Switch and associated Small Form-Factor Pluggable Transceivers (SFPs) for use in Fibre Channel applications in typical Storage Area Networks (SANs).

Overview

The twelve-port switch provide 1 or 2 Gigabit per second (Gb/s) Fibre Channel support and the flexibility of SFP-based design in a 1U full-rack size. The switch is designed as a twelve-port central interconnect for Fibre Channel applications and supports the ANSI FC-AL standard.

Note: Nodes include host computers, servers, and storage arrays.

Devices are connected to the switch through Small Form-factor Pluggables (SFPs) transceivers and cables. Each attached node has 1 or 2 Gigabit-per-second (Gb/s) of available bandwidth; however, all ports must be set to the same speed. Ports with no inserted SFPs or with inoperative nodes are bypassed. The switch’s LED indicators provide status information to service personnel to indicate whether the port is active or bypassed.

Features

The switch incorporates the following features:

• InSpeed™ Techn olog y

• Operating speeds of either 1.0625 or 2.125 Gb/s.

• Standard 1U size for easy installation into standard rack or placement on a tabletop.

• Twelve SFP ports for total cabling flexibility and scalability.

• Management through the switch’s integrated web server or command line interface (CLI).

• 10BaseT Ethernet and RS-232 Serial ports on the switch.

• Switching and non-switching operating modes.

• System and port status LED indicators

• Auto-sensing, universal power supply supporting 100 to 250 VAC and 50 or 60 Hz.

InSpeed™ Technology 2

Important safety, electromagnetic compatibility, and regulatory information is contained in the guide titled Safety & Regulatory Guide. The installation and use of this product must be in accordance with the information given in that guide.

Vixel Model 335 Installation & Configuration Guide CHAPTER 1 Introduction

Fibre Channel-Arbitrated Loop

The Fibre Channel-Arbitrated Loop (FC-AL) is an ANSI standard (X3T11) designed to provide shared bandwidth over low-cost media. Early adopters primarily use the SCSI protocol transported over Fibre Channel for distributed server and storage cluster applications. The switch is a central point of interconnect designed to maintain a faulttolerant physical loop topology.

InSpeed™ Technology

Vixel’s InSpeed™ technology enables the switch’s router to properly utilize the switch core in sending data from one port to another. This process allows for multiple, simultaneous conversations between ports — effectively multiplying bandwidth. Using an advanced switching architecture that couples a non-blocking crossbar switch with unique port logic and per-port SERDES', the InSpeed™ technology creates the industry’s highest-density Fibre Channel switch.

This technology provides the same performance as switches that support FC-SW2, while solving the latency problems associated with large FC-AL loops. During initialization, InSpeed™ connects all devices together in a standard FC-AL2 loop. Upon completion of the initialization process, InSpeed™ transitions to switching mode. When arbitration is attempted, InSpeed™ analyzes connections and routes traffic directly to the destination port.

The InSpeed™ switch is bufferless and operates on only the lower seven bits of the full Fabric address field. Aside from the time it takes to complete a LIP sequence, the switch operates at full switching bandwidth that reaches wire speeds of 200 MB/s.

CHAPTER 2 Installation

Unpacking the Switch

To unpack the switch:

1. Inspect the outer shipping container for any damage that may have occurred in shipping and report any sign of damage to the appropriate shipping agency.

2. Remove the switch from the shipping container; save the shipping container, foam, and anti-static bags—returning the switch in any other container or packing material may void its warranty.

3. Inspect the switch thoroughly. (If any signs of damage are seen, notify your sales representative and/or the shipping agency.)

Installing the Switch

You can install the switch into an equipment rack or place it on a desktop.

Note: For information on environmental requirements, see “Operating Conditions” on page 59.

To mount the switch in a rack, consult the installation documentation that shipped with the rack-mounting kit (ordered separately).

To place the switch on a desktop:

1. Turn the switch upside down so the case bottom is facing up.

2. Install a self-adhesive pad on each corner of the switch (prevents surface damage) at the corner marks on the switch underside.

3. Turn the switch right side up so the case bottom is facing down.

Note: The plug on the power cord is intended to serve as the disconnect device. To cycle power to the switch, remove and reconnect the switch’s power cord.

4. Attach one end of the switch’s power cord to the switch’s power inlet socket and the other end to a properly earthed receptacle (outlet).

5. Insert the power cord firmly into the power inlet socket. The switch is now powered on. The switch automatically executes a Power-On Self

Test (POST) and its LEDs display the test results (for a description of the POST sequence, see “Performing a Power On Systems Test” on page 4).

Vixel Model 335 Installation & Configuration Guide CHAPTER 2 Installation

Using Small Form-Factor Pluggable (SFP) Transceivers

The switch supports any SFP module that complies with the SFP specification as produced by MSA consortium.

The SFPs are “hot-pluggable” into the switch which allows host computers, servers and storage modules to be added dynamically without requiring power removal from the switch or any connected devices.

Small Form-Factor Pluggable (SFP) Installation

An SFP plugged into the switch will be automatically inserted when it is ready to begin initialization.

To insert an SFP, slide the SFP into the port, ensuring the correct orientation, until the latch clicks into place.

Small Form-Factor Pluggable (SFP) Removal

Removal of SFPs from a switch port causes the automatic bypass of that port. The remaining switch ports continue to operate normally with no degradation of system performance.

To extract an SFP, determine first what kind of extraction mechanism the SFP has.

Note: Most SFPs require you to remove the cable prior to removing the SFP from the port.

If the SFP has a removal tag, pull the removal tag to extract the SFP from the port.

If the SFP has a small plastic slider on the bottom side under the optical connector,

simultaneously push in the slider and pull out the SFP. If the SFP has a bale (small metal clasp), unlatch the bale and pull on it to extract

the SFP from the port.

Performing a Power On Systems Test

When the switch is powered on, the switch runs through Power-On Self Test (POST) diagnostics to verify the fundamental integrity of the switch box.

1. All switch LEDs turn on (LEDs illuminate) for approximately two seconds during power on, then all LEDs—except for the Power LED—turn off (LEDs extinguish).

2. If the port bypass LEDs are blinking at a constant rate and the Switch Fault LED is on, the switch has detected a hardware fault—contact an authorized service person.

Page 8

Vixel Model 335 Installation & Configuration Guide CHAPTER 2 Installation

Setting Up the Switch

Before the switch can establish communication with your network, its IP Address needs to be changed from its default value.

To set the IP Address:

1. Attach one end of an RS-232 null modem cable to the serial port on the workstation; attach the other end to the RS-232 port on the switch.

2. For Unix workstations, type the following command at a Unix prompt (where SerialPortDevicePath is the filepath to the serial port used for connection):

cu -s 19200 -b 8 -1 SerialPortDevicePath

For Windows® platforms, open a terminal session through a terminal emulation program (such as HyperTerminal) with the appropriate serial port (for example, COM1) and the following serial port parameters:

• Bits per second: 19200

• Data bits: 8

• Parity: None

• Stop bits: 1

• Flow control: Xon/Xoff You are now connected to the CLI.

3. To log onto the CLI, type li at the prompt, then type the password (the default password is password).

4. To change the switch’s IP parameters, type co and then type 1 to change the switch’s IP address.

5. If you want to change the switch’s netmask and default gateway, type 2 and 3, respectively.

6. Type 5 to save changes and reset the management agent. (The management agent must be reset for the change to take affect.)

7. To log off the CLI, type lo at the prompt.

For more information on configuring the switch through the CLI, see “Using the Command Line Interface (CLI)” on page 36.

Attaching Devices

To attach devices to the switch:

1. Insert an active (that is, Ethernet hub- or Ethernet switch-attached) Ethernet RJ-45 twisted pair cable into the switch’s 10BaseT management port and ensure that the Enet Act (Green) LED is on (LED illuminates).

Note: You can attach cables to SFPs before or after SFP insertion (the switch bypasses ports that do not have attached cables).

2. Remove dust covers or plugs from the SFPs, if provided.

3. For each device: a. Attach a cable to the device.

CAUTION: Forcing an SFP into a port may damage the SFP and/or port.

b. Attach the other end of the cable to a SFP and insert the SFP into a switch port,

using minimal pressure and fitting the SFP housing’s integral guide key into the port until the SFP’s tabs click into place.

Page 9

Vixel Model 335 Installation & Configuration Guide CHAPTER 2 Installation

Note: FC-AL compatible nodes must perform initialization procedures upon power-up in order to function properly. It is the responsibility of the Fibre Channel driver software on FC-AL nodes to perform the initialization or reinitialization (depending on its prior state of operation).

4. Make sure the switch and any other connected switches or hubs are powered on.

5. Power on the storage devices (such as JBODs and RAIDs), then power on the hosts. The network initializes.

6. Check all port LEDs. For more information on Port LED status, See “Port LEDs” on page 7.

7. Check the green Switch Op (Switch Operational) LED. If the Switch Op LED is lit, all zones with inserted devices are operational. If the Switch Op LED is blinking in a multiple zone configuration, one or more zones are operational while others are not. If the Switch Op LED is off, no operational zones exist or no devices are attached.

Note: Improper initialization could be the result of a defective or inoperative host bus adapter card or device. Consult the vendor’s documentation for adapter diagnostic procedures.

Understanding the Switch’s LEDs

You can check the system and port status through the Light-Emitting Diodes (LEDs) on the switch.

The switch utilizes two sets of LEDs to indicate switch and port status:

1. System LEDs – Six separate LEDs that indicate the status of the switch separate from the Port LEDs.

2. Port LEDs – Two LEDs per switch port that indicate status of that specific port

Figure 2-1. Switch features diagram

Power On

When powering on the switch, all LEDs turn on for two seconds and then off for two seconds except for the Power LED, which remains lit while the switch is powered.

System LEDs

There are six LEDs that indicate the status of the switch, independent of the port LEDs:

When lit, the switch is plugged in and the internal power supply is functional.

Switch Fault

(yellow LED)

Indicates that the internal hardware self-test failed. When lit, the switch will not function. -or-

Indicates that a fan has stopped operating or the ambient temperature has exceeded 45°C. When lit, the switch is still functional but requires immediate attention. The LED will turn off when the detected condition is corrected.

Switch Op

(green LED)

Indicates whether the zones are initialized and operational. If the Switch Op LED is lit, all zones with inserted devices are operational. If the Switch Op LED is blinking in a multiple zone configuration, one or more zones are operational while others are not. If the Switch Op LED is off, no operational zones exist or no devices are attached.

2 Gb/s

An explanation of the Port LED indicators is listed below:

SFP

Status

LED

Port

Bypassed/

Activity

LED

Indication

Off Off Normal status of operation for ports in which SFPs

are not installed. The port will be in the bypass state, which precludes the port from participating in the network.

On Off Normal operation. Port and device are operational.

On On

(Yellow)

Bypass. The port is non-operational due to loss of signal, poor signal integrity, or the attached node is sending LIP(F8,xx). This is the normal status condition when the SFP is present but not attached to a FC-AL node, or if it is only attached to a cable assembly with nothing attached at the opposite end. Replacing such a port (or replugging the same port twice) is considered to be a configuration change, which should initiate the Loop Initialization Procedure by the attached device.

Off On

(Yellow)

Tx Fault. The port is non-operational due to an SFP transmitter fault or improperly-seated SFP.

Off Blinking

(Yellow)

The port is being manually controlled by a management entity.

Blinking Blinking

(Yellow)

A management entity is forcing a port beacon to locate a particular port on the switch.

On On

(Green)

A connection has been made with the port. Note: This LED is only applicable when the port is operating in switching mode. If the port is in switching mode and the LED is off, the port is not currently involved in a transaction.

Page 12

Vixel Model 335 Installation & Configuration Guide CHAPTER 2 Installation

Cascading Switches

Cascading allows you to connect two or more switches together to increase the number of ports and available devices. The switch allows you to link up to 12 switches. Multiple cascades between switches provide link and communication redundancy. You may have up to three cascades between a pair of switches.

Note: The primary switch disables the transceivers on all redundant connections, so only the primary cascade is enabled. If the primary cascade goes down, another cascade is then enabled.

The primary cascade is determined by the order of discovery in the primary switch (the switch with the lower Serial Number). If the primary cascade fails in either switch, an automatic failover occurs on one of the other cascades.

Figure 2-4. Cascading Switches in Overlapping Zones

Cascading with Non-Overlapping Zones

There are certain cascade restrictions when using non-overlapping zones. The following examples outline these restrictions.

1. You may only have multiple cascades between switches in Zone 1.

CHAPTER 3 Management

Overview

The switch utilizes both a Web Manager interface and a Command Line Interface (CLI) to manage the switch. You can change the switch’s device identification, upgrade firmware, configure switch settings and policies, define severity levels for event messages, and configure zoning.

Using the Web Manager

The Web Manager enables you to manage and monitor a switch from any networkconnected computer. (Supported browsers are Netscape Navigator 4.7 or higher and Microsoft Internet Explorer 5.0 or higher. The browser needs to be Javascript-enabled.) With the Web Manager, you have the added benefits of easy navigation, simultaneous configuration of multiple ports, and named—rather than enumerated values within complex tables.

Connecting to the Web Manager

For a workstation to connect to the Web Manager, it must have access to the network on which the switch is connected.

If you need to verify the switch’s IP address, log into the switch’s command line interface through a serial link (see “Connecting to the CLI” on page 36).

To connect to the Web Manager:

1. Make sure the switch is connected to your network.

2. On a network-connected computer, open a web browser (such as Netscape Navigator or Microsoft Internet Explorer); in the URL text box, enter the switch’s address (DNS name or IP Address).

OS Information

The Ordered Sets Information page displays the Ordered Sets that are being transmitted on the switch by their associated port number.

To view the Ordered Sets Information page:

1. Click FC Switch. The FC Switch Information page appears.

2. Click OS Info. The Ordered Set Information page.

Figure 3-10. Ordered Set Information Page

If there is a connection, then the Ordered Set transmission information for that connection is depicted by an "X".

A list of the Ordered Sets and their indications follows:

Detection Indication

Non-Overlap Zone Displays the zone for which the port is configured.

Transceiver Displays the status of the inserted transceiver in the port.

Sync A stable signal has been detected and IDLEs transmitted.

Match The ordered set or pattern selected under the Match area has

been detected.

EOF An End-of-Frame (EOF) delimiter has been detected; frames are

present on the loop. (An EOF immediately follows the CRC of a frame and signals the frame’s end.)

SOF A Start-of-Frame (SOF) delimiter has been detected; frames are

present on the loop.

IDLE Sequences of IDLEs are being transmitted to maintain link

activity; no other data is being transmitted.

ARBff ARB(FF)s are being transmitted to maintain link activity; no

other data is being transmitted.

ARB A port is arbitrating for loop access to perform a task.

Page 25

Vixel Model 335 Installation & Configuration Guide CHAPTER 3 Management

RRDY The receiving node on this port has sent an R_RDY signal,

indicating that it is ready for a frame to be transmitted over the link.

CLS The port is attempting to begin the process of closing the current

loop circuit.

OPN The port is attempting to open communications with another

port on the loop. Note: As is the case with some ordered sets, an OPN may not go all the way around the loop, instead stopping at its destination.

LIP F8 A non-switching port has detected a loop failure on its receive

input, is notifying other ports, and is determining whether the loop is still operational. Some events that could cause the port to detect loop failure follow:

• A device in the loop has failed.

• A device in the loop has been powered off.

• The physical connection between the transmitter and receiver is broken.

• Activating the port bypass circuit does not typically result in a loop failure.

LIP F7 A loop port is in the non-participating mode and is attempting

to win arbitration and begin initialization, possibly because the port was reset or is powering up. Sometimes the port is sending this sequence to another, hot-cascaded switch like a new initiator being inserted in the loop.

LIP A Loop Initialization Primitive (LIP) sequence has been detected

and action has been taken.

Unknown The switch can not determine what is being transmitted.

InvTxWd An invalid transmit word has been detected.

CRC Err A Frame CRC error has been detected.

Pt-to-Pt A point-to-point connection has been detected.

Each Port can operate independently of the other ports except in String mode.

Mode Description

auto This setting automatically configures the connection type based on

information sent by other InSpeed switches. The default setting is Auto for InSpeed-based managed switches.

none The port is disabled.

tree A port that allows arbitration fairness to other cascaded InSpeed-

based switches or ports connected to end devices. If the port is a tree port then the ARB (Arbitrate) is sent down the port and, when the ARB is received back at the ASIC, a connection is made between the source and destination ports. All ports are viewed as 100% FC_AL compliant.

string A specially pre-allocated port designed to maintain fairness when

two or more InSpeed-based storage switches are serially cascaded. When the destination port is a string and an OPN is received on the ASIC, an ARB is transmitted throughout the total string cascade loop to alert all devices to enforce the Loop fairness rules. Therefore, if two devices try to ARB for the loop at the same time, the higher Priority AL_PA will win the cascade first, the lower priority one will follow. Note: There must be two string ports on a zone. The port is configured for a pair of string ports to other switches.

Policy Settings

Policies define switch operation and determine how the switch handles error recovery. The Policies page displays the switch policies that are enabled or disabled.

To view the policy settings, click Policy. The Policies page appears.

Figure 3-20. Policies Page

The displayed settings are listed below:

Switch Policy Description

Smart Insertion When this policy is enabled, the switch LIPs on the insert of a new

port and waits for LIP(f7)s to return prior to insertion. Also ensures that data meets the requirements of Fibre Channel Arbitrated Loop (FC-AL) and allows sub-policies to be enabled.

Auto Cascade* When a port is connected to another Vixel Model 335 switch, the

switch will automatically configure the port to the connected device type.

Bad Zone recovery* The switch reinitializes the zone and will bypass zone ports that are

down. The switch will bypass all ports when:

• Zone 1 has a least one transceiver with a signal and the port is in auto mode.

• No ports in the zone are in forced insert mode (Port Control).

• The zone state is down.

No Data Recovery* The switch will bypass a port if no K characters (Ordered Sets) are

detected for 100 usecs. The switch will try to reinsert the port upon detection of valid K characters.

LIP(F8) Recovery* The switch will bypass a port if a LIP(F8) is received. The switch will

try to reinsert the port when no more LIP (F8)s are received.

LIP on Port Bypass* When a port is bypassed, it issues LIP(F7)s to other zone members.

Bypass on Bad OS Threshold*

When a port exceeds the threshold of Ordered Set errors within ten seconds, the switch bypasses the port. Note: The threshold can be

adjusted. (2

– 1, the maximum expected error rate is one error

within 15 minutes.)

Page 33

Vixel Model 335 Installation & Configuration Guide CHAPTER 3 Management

To update the switch’s policies:

1. Click Change Settings on the Policy page. The Policies page appears with fields

available for modification.

Figure 3-21. Policies (Change Settings) Page

2. You can select whether to enable or disable a specific policy, set thresholds on certain policies, and select specific ports for the LIP on Insertion and Port Test Before Insertion policies.

3. Once you have made your changes, click Update Policies to accept the changes.

4. Click Back to Policy Page to review the new settings.

Bypass on CRC Error Threshold*

When a port exceeds the threshold of frame CRC errors within ten seconds in Zone 1 and in switching mode, the switch bypasses the port. Note: The threshold can be adjusted.

Bypass on Clock Delta Error

When this policy is enabled, the switch compares the detected line clock through the frame and the number of fill words inserted or deleted versus the switch’s internal clock. If the derived clock delta is too high, the port is bypassed.

LIP on Insertion* When a port inserts into a zone, it issues LIP(F7)s to other zone

members.

Port Test Before Insertion*

Before allowing a port to insert into a zone, the port is monitored for proper Loop Port State Machine (LPSM) protocols. (At least one of the devices on the port must be a Loop Initialization Master (LIM) to follow these protocols.)

* To set this policy, ensure that Smart Insertion is enabled.

Page 34

Vixel Model 335 Installation & Configuration Guide CHAPTER 3 Management

Zone Settings

The switch uses two types of port zoning: Overlapping and Non-Overlapping Zones.

With overlapping zoning, devices on one port are not allowed to see devices on another port, yet those same devices can both see a device on a third port.

Figure 3-22. Overlapping Zones

In Figure 3-22, Zone 1 includes ports 1, 3, and 4, while zone 2 includes ports 2, 4 and 5. Port 4 overlaps both zones. Devices on ports 1, 3, and 4 can see each other and devices on ports 2, 4, and 5 can see each other, but devices 1 and 3 cannot see devices 2 and 5. Devices on port 4 can see all the devices on ports 1, 2, 3, and 5.

Non-overlapping zoning enables the switch to be divided into separate environments, where each environment sustains a complete 127-device AL_PA space.

Figure 3-23. Non-overlapping Zones

In Figure 3-23, Zone 1 devices operate independently of devices in Zone 2. Nonoverlapping zoning allows for true LIP isolation. If a LIP occurs in one non-overlapping zone, it will not affect the operation or traffic occurring in a different zone.

To view the zoning information, click Zoning. The Zone Information page appears.

Figure 3-24. Zone Information Page

Page 35

Vixel Model 335 Installation & Configuration Guide CHAPTER 3 Management

The Zone Information page displays the current zoning configuration, the ports in each zone, the zone state, the init count, and the time duration ("up time") for the zone. The displayed settings are listed below:

Overlapping Zones

Overlapping zoning can only be implemented in Zone 1 and the switch must be operating in switching mode. To participate in overlapping zoning, each port must have their cascade mode configured to "auto".

If the switch is operating using non-overlapping zoning, you can still configure overlapping zoning within the default zone. If a LIP occurs on any port in the default zone, it will affect every port in the default zone, regardless of any overlapping zone configurations. Overlapping zones do not support LIP isolation.

To view the overlapping zoning, click Overlapping. The Overlapping Zone 1 Information page appears.

Figure 3-25. Overlapping Zone 1 Information Page

Setting Description

Zone number The zone number on the switch (1-12).

Port number(s) The port numbers that are assigned to the specified zone.

Zone state The current state of the zone; either "up" or "down".

Init Count The number of times a zone has transitioned from an "down" state to

an "up" state.

Up Time The amount of time that the zone has been operational.

Page 36

Vixel Model 335 Installation & Configuration Guide CHAPTER 3 Management

To configure the overlapping ports:

1. Click Change Overlapping Zones. The Overlapping Zone 1 Information page appears with the ports available for modification.

Figure 3-26. Overlapping Zone 1 Information (Configuration) Page

2. Click the appropriate check box for the two ports. If the check box is selected (checked), the two ports can communicate with one another. If the check box is empty (not checked), the two ports are blocked from communicating with one another.

3. Once you have configured the overlapping ports, click Update Overlapping Zoning to accept the changes.

To view the your changes, click Back to Overlapping. Blocked ports are displayed in red, while non-blocked ports are displayed in gray.

Non-Overlapping Zones

Note: Ports 11 and 12 can only be in Zone 1.

The non-overlapping zones feature enables you to assign each port on the switch to one of 12 available zones. Each zone is unique which allows for 6 separate zones to function on the same switch. With non-overlapping zoning enabled, each zone is totally independent and LIPs on one zone do not affect the other zones.

The default zone for the switch is Zone 1. Ports 11 and 12 are always included in Zone

The switch provides LIP isolation through the LIP confinement properties of nonoverlapping zoning. A LIP occurring in one zone will never affect the traffic or operations in another zone. Each zone operates completely independent of other nonoverlapping zones.

Page 37

Vixel Model 335 Installation & Configuration Guide CHAPTER 3 Management

Note: You can have simultaneous overlapping and non-overlapping zoning. Overlapping zoning operates in Zone 1 and non-overlapping zoning operates in Zones 2-12.

To view the non-overlapping zoning, click Non Overlapping. The Non Overlapping Zone Information page appears.

Using the Command Line Interface (CLI)

The Command Line Interface (CLI) allows you to complete several switch management tasks over Ethernet through a telnet session or through a direct serial link. While both the CLI and Web Manager interfaces allow you to view switch information and configure switch settings, the CLI also allows you to enable or disable DHCP requests, change the CLI/Web Manager password, manage traps, and complete several other switch management functions.

Connecting to the CLI

Note: You may have up to 10 concurrent telnet sessions accessing the switch.

You can connect to the CLI over the telnet interface or the serial link interface. To connect over Ethernet through telnet interface:

1. Make sure the Vixel Managed Switch is connected to an Ethernet network via the switch’s Ethernet connection and that the monitoring workstation can access this Ethernet network.

2. Make sure that you know the switch’s IP address before connecting to the CLI. (the default IP Address is 0.0.0.0)

3. At a command line prompt, type telnet IP (where IP is the switch’s IP address).

You are now connected to the CLI and ready to log on.

To connect through a serial link:

1. Attach one end of an RS-232 null modem cable to the serial port on the workstation; attach the other end to the RS-232 port on the switch.

2. For Unix workstations, type the following command at a Unix prompt (where SerialPortDevicePath is the filepath to the serial port used for connection):

cu -s 19200 -b 8 -1 SerialPortDevicePath

3. For Windows® platforms, open a terminal session through a terminal emulation program (such as HyperTerminal) with the appropriate serial port (for example, COM1) and the following serial port parameters:

• Bits per second: 19200

• Data bits: 8

• Parity: None

• Stop bits: 1

• Flow control: Xon/Xoff

You are now connected to the CLI and ready to log on.

Logging On and Off

To log onto the CLI (once connected as shown above), type li at the prompt, then type the password (the default password is password).

To log off the CLI, type lo at the prompt.

Make sure you change the password after you log on the first time.

Changing the Switch’s IP Parameters

To view the current switch configuration, type co at the prompt. The Configuration Menu appears:

Before the switch can establish communication with your network, its IP address needs to be changed from its default value.

To change the switch’s IP parameters:

1. Type the option number (1-4) of the desired setting.

2. Enter a new value for that setting.

3. Type 5 to save changes and reset the switch. (The switch must be reset for the change to take affect.)

Enabling or Disabling DHCP Requests

When DHCP is enabled, the switch sends a DHCP request for its correct IP parameters (address, subnet mask, and default gateway) during power on. If a DHCP server responds, the switch automatically changes its IP settings.

Note: The default setting for the DHCP option is "disabled".

If you want to enable DHCP, ensure that there is a DHCP server connected to the same subnet as the switch. (For instructions on setting the switch’s IP parameters through a DHCP server, see the server documentation.)

If DHCP is enabled and a DHCP server is not found, the DHCP request will fail and the switch’s IP parameters will be incorrect. You will then have to connect through the serial port using the CLI, disable the DHCP mode, and manually configure the switch parameters.

To enable automatic DHCP requests from the switch:

1. Type co, then type 4.

The DHCP status is toggled to either enable or disable and the current setting is displayed.

2. Type 5 to save changes and reset the switch. (The switch must be reset for the change to take affect.)

Policies

Note: The mc command must be entered prior to issuing one of the submenu commands.

You can view the current global policy settings and configure the switch to use the policies you select.

Note: Before you type a command for port policies, select the desired port by typing po # (where # is the desired port number).

An explanation of the available policies follows:

Policy Description

Smart insertion

Ensures that data meets the requirements of Fibre Channel Arbitrated Loop (FC-AL) and allows sub-policies to be enabled.

Bad zone recovery

Reacts to bad zone indications by putting all ports through the normal insertion process and allowing only those ports sending ordered sets to insert.

No data recovery

The switch will automatically bypass a port if no K characters (Ordered Sets) are detected within a certain timeframe. The switch will try to reinsert the port upon detection of valid K characters.

LIP F8 recovery

Reacts to LIP(F8)s (indicating non-functional zones) by putting all ports through the normal insertion process and allowing only those ports not sending LIP(F8)s to insert.

LIP on port bypass

Requires bypassed ports to send LIP(F7)s to other zone members.

Auto cascade

When this policy is enabled, the switch will automatically configure itself and any other detected Vixel Inspeed devices in a cascade configuration.

Note: This policy must be set to enabled if auto cascading on a port is enabled.

Bypass at max OS err

When this policy is enabled, the switch bypasses a port when that port exceeds the threshold of Ordered Set errors within a certain timeframe. (This policy applies to Zone 1 only.) The default timeframe is 10 seconds (see the Error Count Threshold setting).

Bypass at max CRC err

When this policy is enabled, the switch bypasses ports that exceed the set threshold of frame CRC errors. Compares the CRC transmitted with a frame to the CRC calculated in the switch. (This policy applies to Zone 1 only.)

Bypass on clock delta err

Bypass on switch stall

When this policy is enabled and switching mode is on, the switch bypasses a stalled port if the connection is not terminated within a certain timeframe (see the Switch Stall Threshold setting).

Clear conn on sw stall

When this policy is enabled, the switch clears the port connection on a switch stall after a certain timeframe (see the Switch Stall Threshold setting).

Page 48

Vixel Model 335 Installation & Configuration Guide CHAPTER 3 Management

To enable or disable a policy:

1. Enter the number for the desired policy.

2. Enter 2 to enable the policy or 3 to disable the policy.

Page 53

Vixel Model 335 Installation & Configuration Guide CHAPTER 3 Management

Setting Description

Control

Enables you to configure control of the port. Select from: (2) auto – the default setting. The switch controls the port and prevents the insertion of incompatible ports which may cause disruption. (3) bypass – removes a port from the zone. Use this mode to troubleshoot ports. (4) extl-loopback – removes a port from the zone and routes the port's receive signal back through the port's transmitter. Use this mode to isolate a specific zone for troubleshooting or test a transceiver’s circuitry and attached media from the node end. (5) force insert – allows ports whose transceivers cannot derive a valid clock or "K" character (Ordered Set) to join the zone. Use this mode cautiously – devices without valid characters may put bad data into the zone, causing the zone to go down. (6) diagnostic-tx – allows you to transmit specific Ordered Sets for testing purposes.

Beacon

When enabled, it forces both port LEDs to flash on and off continuously on the selected port. You can use the beacon feature to remotely alert a technician to take action on a specific port as identified by a system administrator. The blinking overrides the state information display until the beaconing is turned off.

Transmitter

Turns the transceiver connected to the port on or off.

Cascade mode

The current cascade mode (auto, none, tree, string) selected for the port. Options: auto – This setting automatically configures the connection type based on information sent by other InSpeed switches. This is the default setting for InSpeed-based managed switches.

none – The port is disabled.

tree – A port that allows arbitration fairness to other cascaded InSpeedbased switches or ports connected to end devices. If the port is a tree port then the ARB (Arbitrate) is sent down the port and, when the ARB is received back at the ASIC, a connection is made between the source and destination ports. All ports are viewed as 100% FC_AL compliant.

string – A specially pre-allocated port designed to maintain fairness when two or more InSpeed-based storage switches are serially cascaded. When the destination port is a string and an OPN is received on the ASIC, an ARB is transmitted throughout the total string cascade loop to alert all devices to enforce the Loop fairness rules. Therefore, if two devices try to ARB for the loop at the same time, the higher Priority AL_PA will win the cascade first, the lower priority one will follow. Note: There must be two string ports on a zone. The port is configured for a pair of string ports to other switches.

LIP on insert

If enabled, when a port inserts into a zone, it issues LIP(F7)s to other zone members.

Non-Overlapping Zoning Configuration

Note: Ports 11 and 12 can only be in Zone 1.

You can have simultaneous overlapping and non-overlapping zoning. Overlapping zoning operates in Zone 1 and non-overlapping zoning operates in Zones 2-12.

The non-overlapping zoning configuration shows the zone status, the port state for each zone, the number of active ports in each zone, and the port numbers that are in each zone.

To view zone configuration by zone, type noz.

The current non-overlapping zoning configuration, by zone, is displayed.

Zone number: Possible values are 1–12. Port State: Possible values are "B" (Bypassed), "I" (Inserted), "D" (Diagnostic

Transmit), "E" (External Loopback), "U" (Unknown), and "?" (Access Error).

Zone State: Possible values are "U" (Up) and "D" (Down).

Note: Each port may only

be in one non-overlapping zone.

To place ports into non-overlapping zones:

1. Type noz to view the current non-overlapping zones configuration.

2. At the prompt, type noz z:p,p,p.. z:p p.. z.. (where z=zone number 1–12 and p=port number 1–12)

Ports on a zone may be separated by a comma or spaces.

Note: Unspecified ports are automatically placed into Zone 1.

Example: noz 2:5,6,7,8 3:9,10 Ports 5-8 are placed in Zone 2, ports 9-10 are placed in Zone 3, and ports 1-4 and

Troubleshooting

Some common troubleshooting situations are listed below with suggested courses of action.

Situation* Recommended Action

No LEDs are on.

Make sure that the switch is plugged into an adequate AC power source (shown in “Operating Conditions” on page 59).

The switch’s Fault LED is on.

Cycle power to the switch. One or more enclosure fans may have failed, or an over-temperature

condition may exist. Contact an authorized service person. If the switch’s Fault LED remains lit, the switch requires repair.

Contact an authorized service person.

The Mgmt Present LED is off.

Contact an authorized service person.

The Mgmt Present LED is blinking continuously.

Power cycle the switch to see if the condition clears. If the Mgmt Present LED continues to blink (and POST has already

completed), firmware may be corrupt or hardware may have failed. Contact an authorized service person.

The Enet Active LED is off during an ethernet connection.

Check the following items:

• Ethernet RJ-45 connection to the Vixel 335 Managed Storage Switch.

• Ethernet connection to the Ethernet switch.

• Power status of the Ethernet switch.

• Power status of the Vixel 335 Managed Storage Switch.

The Switch Op LED is off or flashing.

Check the following items:

• Ports (LEDs and SFPs).

• Cabling.

• Bad / misbehaving HBA / FC controller at the node end.

Note: The switch automatically recovers all zones for the most common failure conditions.

* LEDs that are on are illuminated; LEDs that are off are extinguished.

• Robert Kembel, A Comprehensive Introduction. Connectivity Solutions, 1998. ISBN 0-931836-84-0.

Problem Recommended Action

SFP installed in one or more ports but no LEDs lit

Verify power cord is firmly seated into switch and is connected to a properly earthed receptacle (outlet).

Check the Power LED to ensure switch is turned on.

SFP installed but only yellow LED is lit

Re-seat the SFP. If the same condition occurs, the SFP is probably faulty and should be replaced.

SFP installed with both green and yellow LEDs lit

The switch is not receiving a valid Fibre Channel signal from the end node (HBA or disk array) or is receiving LIP(F8).

1) Ensure that the device is powered on and operating properly.

2) Unplug the fiber cable from the node and verify that an optical signal is present on the cable receiver lead.

3) Examine the connectors on the HBA or disk controller for correct and proper connection. If optical power meter is available, verify the device is transmitting a signal.

If there is no signal present, the device may require rebooting, device drivers may need to be reinstalled, or the HBA or disk controller hardware may require servicing.

If a signal is present on both the cable lead and the end node, the HBA or disk controller may require service.

SFP installed with only green LED lit, but devices are not communicating

The switch is receiving a valid Fibre Channel signal from the end device (HBA or disk), but no upper level protocols are active.

1) Verify that the proper HBA device drivers are loaded for the appropriate operating system and that the host has been configured to recognize attached disk devices.

2) Check the Switch Op LED. If the Switch Op LED is on, the devices have completed initialization. If the Switch Op LED is off, the devices were not initialized. Remove all the devices and add one device at a time to isolate the device responsible for the failure.

3) Improper initialization could result from a defective or inoperative adapter card or device. Run adapter diagnostics with a loopback connector to see if the adapter is working properly.

4) Unplug the fiber cable from the end node and verify that an optical signal is present on the cable receiver lead. If no signal is present, the receiver lead of the cable may be bad and the device may be streaming LIP(F8). Ensure that all cascaded ports are correctly configured.

APPENDIX E Glossary

AL_PA or Arbitrated Loop Physical Address

A one-byte value used to identify a port in an Arbitrated Loop topology. The value of the AL_PA corresponds to bits 7:0 of the 24-bit Native Address Identifier.

Arbitrated Loop A Fibre Channel topology structured as a loop and requiring a

port to successfully arbitrate prior to establishing a circuit to send and/or receive frames.

Arbitration The process of selecting one respondent from a group requesting

service at the same time.

Close (CLS) An Arbitrated Loop protocol used to terminate a loop circuit.

Current Fill Wor d

The fill word that the Loop Port State Machine uses when a fill word is to be transmitted.

DHCP Dynamic Host Control Protocol. An Internet-based protocol

enabling nodes to dynamically acquire network addresses for periods of time.

Duplex Cable Two fibers in one cable suitable for duplex transmission.

Fiber Optics Light transmission through optical fibers for communication or

signaling

Fibre Channel Fibre Channel is a data transfer interface technology that maps

several common transport protocols including IP and SCSI, allowing it to merge high-speed I/O and networking functionality in a single connectivity technology. Fibre channel is an open standard as defined by ANSI and OSI standards and operates over copper and fiber optic cabling at distances of up to 10 Kilometers. It is unique in its support of multiple interoperable topologies including point-to-point, arbitrated-loop and switching and it offers several qualities of service for network optimization. With its large packet sizes, Fibre Channel is ideal for storage, video, graphic and mass data transfer applications.

LED Light-Emitting Diode. A status indicator on a switch.

LIP/LIP sequence Loop Initialization Primitive. A sequence used to accomplish

one or more of the following objectives:

• Initiate a procedure that results in unique addressing for all nodes.

• Indicate a switch failure.

• Reset a specific node.

Mb/s Megabits per second, 1,024,000 bits per second.

MB/s Megabytes per second, 8,192,000 bits per second.

One byte = 8 bits

Node An entity with one or more N_Ports or NL_Ports.

Non-overlapping Zones

Enables the switch to be divided into separate environments, where each environment sustains a complete 127-device AL_PA space.

Open An Arbitrated Loop protocol used to establish a switch circuit.

Overlapping Zones

Devices on one port are not allowed to see devices on another port, yet those same devices can both see a device on a third port.

Protocol A data transmission convention which may include timing,

control, formatting, error detection with correction and data representation.

SCSI Small Computer System Interface. Standard interface for storage

modules.

SFP Small Form-Factor Pluggable transceiver. These transceivers are

fully compliant with the FC-PI and MSA standards and occupy less than half the board space of the existing GBIC products.

SNMP Simple Network Management Protocol. A protocol for

managing systems and devices in a network. Supports the retrieving data, writing data, and setting traps indicating events.

Top ol og y The logical and/or physical arrangement of stations on a

network. Fibre Channel topologies include point-to-point, Arbitrated Loop, and switched fabric.

Tra ns ce iv er A device that converts one form of signaling to another for both

transmission and reception. SFPs and GBICs are transceivers.

Zoning Dividing a network into separate areas to group devices and

isolate traffic.
