xxiv SAN48B-5 Installation, Service, and User Guide

Chapter 1. Introducing the SAN48B-5

The IBM System Storage SAN48B-5 is a 48-port auto-sensing 2, 4, 8, or 16 Gbps as well as 10 Gbps Fibre Channel (FC) switch for Fibre Channel Storage Area Networks (SANs). The SAN48B-5 is an enterprise-class switch that is designed to handle the large-scale SAN requirements of an enterprise, and can also be used to address the SAN requirements of small to medium-sized workgroups.

The switch's 48 ports in a one rack-unit (1U) height enable the creation of very dense fabrics in a relatively small space.

The SAN48B-5 offers Ports on Demand (POD) licensing as well. Base models of the switch contain 24 ports, and up to two additional 12-port POD licenses can be purchased. The switch provides excellent overall value as the foundation of a SAN with the ability to grow with an organization’s SAN needs.

The SAN48B-5 supplies Reliability, Availability, and Serviceability (RAS) performance and scalability requirements of an enterprise switch along with interoperability and ease-of-use advantages.

The switch can also be configured in Access Gateway mode that lets you configure your Enterprise fabric to handle additional N_Ports instead of domains. By reducing the number of domain IDs and ports you simplify configuration and management in a large fabric. Switches in AG mode are logically transparent to the host and the fabric. You can increase the number of hosts that have access to the fabric without increasing the number of switches.

The switch's depth of less than 18 inches allows for greater installation flexibility.

This chapter provides the following information:

v “Switch capabilities” v “Switch components” on page 2 v “Port side of the switch” on page 3 v “Nonport side of the switch” on page 4

Site preparation and installation requirements

The following conditions are required to ensure correct installation and operation.

Electrical requirements

For successful installation and operation of the switch, ensure that the following electrical requirements are met:

v The primary outlet is correctly wired, protected by a circuit breaker, and

grounded in accordance with local electrical codes.

v The supply circuit, line fusing, and wire size are adequate, as specified by the

electrical rating on the switch nameplate.

v The power supply standards are met. See “Power supply specifications” on page

36. Attention: To maximize fault tolerance, connect each power cord to a separate

power source.

Environmental requirements

For successful installation and operation of the switch, ensure that the following environmental requirements are met:

v At a minimum, adequate cooling requires that you install the switch with the

intake side facing the cool-air aisle.

v All equipment in the rack should force air in the same direction to avoid intake

of exhaust air.

v A maximum of 102 cubic meters/hour (60 cubic feet/minute) and a minimum of

74..8 cubic meters/hour (44 cubic feet/minute) of air flow is available to the air intake.

v The ambient air temperature does not exceed 40° C (104° F) while the switch is

operating.

Cabinet requirements

For successful installation and operation of the switch in a cabinet, ensure that the following cabinet requirements are met:

v The cabinet must be a standard EIA cabinet. v A cabinet space that is one rack unit (1U) high; 4.45 cm (1.75 inches) high and

48.3 cm (19 inches) wide.

v The rack kit option for the switch uses rails that are slimmer than standard rails

to accommodate the slightly wider chassis. Be sure to use one of these kits. Do not use standard rails to install the switch in a rack, they will not fit with the switch.

v The equipment in the cabinet is grounded through a reliable branch circuit

connection and maintain ground at all times. Do not rely on a secondary connection to a branch circuit, such as a power strip.

v Airflow and temperature requirements are met on an ongoing basis, particularly

if the switch is installed in a closed or multicabinet assembly.

v The additional weight of the switch does not exceed the cabinet’s weight limits

or unbalance the cabinet in any way.

6 SAN48B-5 Installation, Service, and User Guide

v The cabinet is secured to ensure stability in case of unexpected movement, such

as an earthquake.

Planning for cable management

Attention: The minimum bend radius for a 50 micron cable is 2 inches under full tensile load and 1.2 inches with no tensile load.

Cables can be organized and managed in a variety of ways, for example, using cable channels on the sides of the cabinet or patch panels to minimize cable management. Following is a list of recommendations:

v Plan for rack space required for cable management before installing the switch. v Leave at least 1 m (3.28 ft) of slack for each port cable. This provides room to

remove and replace the switch, allows for inadvertent movement of the rack, and helps prevent the cables from being bent to less than the minimum bend radius.

v If you are using ISL Trunking, consider grouping cables by trunking groups. The

cables used in trunking groups must meet specific requirements, as described in the Fabric OS Administrator’s Guide.

v For easier maintenance, label the fiber optic cables and record the devices to

which they are connected.

v Keep LEDs visible by routing port cables and other cables away from the LEDs. v Use hook and loop style straps to secure and organize fiber optic cables. Do not

use tie wraps with optical cables; they can be easily overtightened and can damage the optic fibers.

Items required for installation

The following items are required for installing, configuring and connecting the SAN48B-5 for use in a network and fabric:

v Workstation with an installed terminal emulator, such as HyperTerminal. v Unused IP address and corresponding subnet mask and gateway address v Serial cable (provided) if not using EZSwitch Setup v Ethernet cable v Brocade-branded SFP+s and compatible cables (Brocade-branded 16 Gbps SFP+s

are required for 16 Gbps performance), as required

v Access to an FTP server or the USB device for backing up the switch

configuration (optional)

Setting up the switch as a standalone unit

Attention: Refer to “Safety notices and labels” on page xiii before starting any installation procedure.

Configuring the switch

Once you have set up the SAN48B-5 in a rack or as a standalone switch, it is time to give it power and a basic configuration. If you are going to use the SAN48B-5 in a single-switch setup, you can use EZSwitchSetup to complete the basic configuration.

See the EZSwitchSetup CD, included with the switch, for more information. You can also use the SAN48B-5 Quick Start Guide. If you do not want to use EZSwitch Setup, follow the instructions in the rest of this section.

To configure the switch, perform the following tasks.

v “Providing power to the switch” v “Creating a serial connection” v “Setting the switch IP address” on page 15 v “Setting the switch date and time” on page 16 v “Installing SFP+ transceivers and connecting cables” on page 19

Attention: Do not connect the switch to the network until the IP address is correctly set.

Providing power to the switch

DANGER

Follow these steps to power on the switch:

1. Connect the power cords to both power supplies

2. Connect the other end of the power cords to power sources on separate circuits

to protect against AC failure. Ensure that the cords have a minimum service loop of 6 in. available and are routed to avoid stress.

3. Power on the power supplies by flipping both AC switches to the “|” symbol. The power supply LEDs display amber until POST is complete, and then change to green. The switch usually requires several minutes to boot and complete POST.

Attention: Power is supplied to the switch as soon as the first power supply is connected and turned on.

4. After POST is complete, verify that the switch power and status LEDs on the left of the port side of the switch are green. See “Port side of the switch” on page 3 for the specific location of these LEDs.

Attention: Do not connect the switch to the network until the IP address is set.

Creating a serial connection

All basic configuration tasks in this guide are performed using a serial connection. Complete the following steps to create a serial connection to the switch.

14 SAN48B-5 Installation, Service, and User Guide

1. Connect the serial cable to the console port on the switch and to an RS-232 serial port on the workstation. If the serial port on the workstation is RJ-45 instead of RS-232, remove the adapter from the end of the serial cable and insert the exposed RJ-45 connector into the RJ-45 serial port on the workstation.

2. Open a terminal emulator application (such as HyperTerminal on a PC, or TERM, TIP, or Kermit in a UNIX environment), and configure the application as follows:

v In a Windows environment:

Parameter Value

Bits per second 9600

Databits 8

Parity None

Stop bits 1

Flow control None

v In a UNIX environment using TIP, enter the following string at the prompt:

tip /dev/ttyb -9600

If ttyb is already in use, then use ttya instead and enter the following string at the prompt:

tip /dev/ttya -9600

Setting the switch IP address

You can configure the SAN48B-5 with a static IP address, or you can use a DHCP (Dynamic Host Configuration Protocol) server to set the IP address of the switch. DHCP is enabled by default. The SAN48B-5 supports both IPv4 and IPv6.

Using DHCP to set the IP address

When using DHCP, the switch obtains its IP address, subnet mask, and default gateway address from the DHCP server. The DHCP client can only connect to a DHCP server that is on the same subnet as the switch. If your DHCP server is not on the same subnet as the switch, use a static IP address.

Setting a static IP address

Complete the following steps to configure the switch with a static IP address:

1. Log into the switch using the default password, which is password.

2. Use the ipaddrset command to set the Ethernet IP address.

If you are using an IPv4 IP address, enter the IP address in dotted decimal notation as prompted.

Ethernet IP Address: 192.168.74.102

If you are using an IPv6 address, enter the network information in colon-separated notation as prompted.

switch:admin> ipaddrset -ipv6 --add 1080::8:800:200C:417A/64 IP address is being changed...Done.

3. Complete the rest of the network information as prompted.

Ethernet Subnetmask: 255.255.255.0

Ethernet IP Address: 192.168.74.102 Ethernet Subnetmask: 255.255.255.0

4. Enter off to disable DHCP when prompted.

Chapter 2. Installing and configuring the switch 15

DHCP [OFF]: off

5. Optionally, verify that the address was correctly set by entering the

ipAddrShow command at the prompt.

6. Record the IP address on the pull out tab provided for this purpose on the port side of the switch.

Setting the switch date and time

The SAN48B-5 maintains the current date and time inside a battery-backed real-time clock (RTC) circuit. The date and time settings are used for logging events. Switch operation does not depend on the date and time; a switch with an incorrect date and time value still functions properly. However, because the date and time are used for logging, error detection, and troubleshooting, you should set them correctly.

Complete the following steps to set the date and time of the switch.

Time zones

You can set the time zone for the switch by name. You can also set country, city or time zone parameters.

If the time zone is not set with the new options, the switch retains the offset time zone settings. The tsTimeZone command includes an option to revert to the prior time zone format. For more information about the --old option, see the Fabric OS Command Reference.

You can set the time zone for a switch using the tsTimeZone command. The tsTimeZone command allows you to perform the following tasks:

v Display all of the time zones supported in the firmware v Set the time zone based on a country and city combination or based on a time

zone ID such as PST

The time zone setting has the following characteristics: v You can view the time zone settings. However, only those with administrative

permissions can set the time zones.

v The tsTimeZone setting automatically adjusts for Daylight Savings Time. v Changing the time zone on a switch updates the local time zone setup and is

reflected in local time calculations.

v By default, all switches are in the GMT time zone (0,0). If all switches in a fabric

are in one time zone, it is possible for you to keep the time zone setup at the default setting.

v System services that have already started will reflect the time zone changes only

after the next reboot.

v Time zone settings persist across failover for high availability.

For more detailed information about the parameters of the tsTimeZone command, refer to the Fabric OS Command Reference.

Local time synchronization

You can synchronize the local time of the principal or primary fabric configuration server (FCS) switch to a maximum of eight external network time protocol (NTP) servers. To keep the time in your SAN current, it is recommended that the principal or primary FCS switch has its time synchronized with at least one

16 SAN48B-5 Installation, Service, and User Guide

external NTP server. The other switches in the fabric will automatically take their time from the principal or primary FCS switch.

All switches in the fabric maintain the current clock server value in non-volatile memory. By default, this value is the local clock server <LOCL> of the principal or primary FCS switch. Changes to the clock server value on the principal or primary FCS switch are propagated to all switches in the fabric.

When a new switch enters the fabric, the time server daemon of the principal or primary FCS switch sends out the addresses of all existing clock servers and the time to the new switch. If a switch with v5.3.0 or later has entered the fabric it will be able to store the list and the active servers; pre-5.3.0 Fabric OS switches will ignore the new list parameter in the payload and will update only the active server address.

If the active NTP server configured is IPv6, then distributing the same in the fabric will not be possible to switches earlier than v5.3.0 because IPv6 is supported for Fabric OS version 5.3.0 and later. The default value LOCL will be distributed to pre-5.3.0 switches.

The tsClockServer command accepts multiple server addresses in either IPv4, IPv6, or DNS name formats. When multiple NTP server addresses are passed, tsClockServer sets the first obtainable address as the active NTP server. The rest are stored as backup servers that can take over if the active NTP server fails. The principal or primary FCS switch synchronizes its time with the NTP server every 64 seconds.

Setting the date

1. Log into the switch using the default password, which is password.

2. Enter the date command, using the following syntax:

date ""mmddHHMMyy""

The values represent the following:

v mm is the month; valid values are 01 through 12 v dd is the date; valid values are 01 through 31 v HH is the hour; valid values are 00 through 23 v MM is minutes; valid values are 00 through 59 v yy is the year; valid values are 00 through 99 (values greater than 69 are

interpreted as 1970 through 1999, and values less than 70 are interpreted as 2000-2069)

switch:admin> date Fri Aug 26 12:29:46 UTC 2011 switch:admin> date "0826123011" Fri Aug 26 12:30:00 UTC 2011 switch:admin>

Setting the time zone

To set the time zone, follow these steps.

1. Log into the switch using the default password, which is password.

2. Enter the tsTimeZone command as follows:

switch:admin> tstimezone [--interactive]/ [, timezone_fmt]

Chapter 2. Installing and configuring the switch 17

Use timezone_fmt to set the time zone by Country/City or by time zone ID, such as MST. The following example shows how to change the time zone to US/Mountain.

switch:admin> tstimezone Time Zone : US/Pacific switch:admin> tstimezone US/Mountain switch:admin> tstimezone Time Zone : US/Mountain

The following procedure describes how to set the current time zone using interactive mode.

1. Enter the tsTimeZone command as follows:

switch:admin> tstimezone --interactive

2. You are prompted to select a general location.

Please identify a location so that time zone rules can be set correctly.

3. Enter the appropriate number or Ctrl+D to quit.

4. At the prompt, select a country location.

5. At the prompt, enter the appropriate number to specify the time zone region or

Ctrl+D to quit.

Synchronizing local time using NTP

Complete the following steps to synchronize the local time of the principal or primary switch with that of an external NTP server.

1. Log into the switch using the default password, which is password.

2. Enter the tsClockServer command.

switch:admin> tsclockserver "<ntp1;ntp2>"

where ntp1 is the IP address or DNS name of the first NTP server, which the switch must be able to access. The second ntp2 is the second NTP server and is optional. The entire operand "<ntp1;ntp2>" is optional; by default, this value is LOCL, which uses the local clock of the principal or primary switch as the clock server. The tsClockServer command accepts multiple server addresses in either IPv4, IPv6, or DNS name formats. When multiple NTP server addresses are passed, tsclockserver sets the first obtainable address as the active NTP server. The others will be stored as backup servers that can take over if the active NTP server fails. The principal or primary FCS switch synchronizes its time with the NTP server every 64 seconds.

switch:admin> tsclockserver LOCL switch:admin> tsclockserver "132.163.135.131" switch:admin> tsclockserver

132.163.135.131 switch:admin>

The following example shows how to set up more than one NTP server using a DNS name:

switch:admin> tsclockserver "10.32.170.1;10.32.170.2;ntp.localdomain.net" Updating Clock Server configuration...done. Updated with the NTP servers Changes to the clock server value on the principal or primary FCS switch are propagated to all switches in the fabric

18 SAN48B-5 Installation, Service, and User Guide

Inter-Switch Link (ISL) Trunking

ISL Trunking is optional software that allows you to create trunking group of ISLs between adjacent switches. Up to eight FC ports on the SAN48B-5 can be used as a trunking group to achieve speeds up to 128 Gbps (256 Gbps full duplex) for optimal bandwidth utilization and load balancing. For more information about Brocade ISL Trunking, see the Fabric OS Administrator's Guide.

Installing SFP+ transceivers and connecting cables

The SAN48B-5 only supports Brocade-branded SFP+ optical transceivers. For the Fibre Channel connections, the switch uses SFP+ transceivers that support any combination of Short Wavelength (SWL), Long Wavelength (LWL), and Extended Long Wavelength (ELWL) optical media. This switch will accept both 16 Gbps and 8 Gbps SFP+ transceivers.

Note: For a listing of transceivers compatible with this product:

v Go to the IBM SAN web page www.ibm.com/systems/storage/san v Select the IBM System Storage SAN48B-5 product link v On the displayed product page, click the Interoperability Matrix link in

the Learn more section.

v In the Interoperability matrix, click the Transceivers link.

If you use an unqualified transceiver, the switchShow command output shows the port in a Mod_Inv state. Fabric OS also logs the issue in the system error log.

The 16 Gbps SFP+ transceivers have an attached pull tab and no latching wire bail. To simplify insertion of the 16 Gbps SFP+ transceivers, it is recommended to connect the cables first, and then insert them as a unit into the port. Figure 8 on page 20 shows the installation of a 16 Gbps SFP+, and Figure 9 on page 20 shows the installation of an 8 Gbps SFP+ with a wire bail latching mechanism.

Installing 16 Gbps SFP+ transceivers

Note: Each SFP+ has a 10-pad gold-plated PCB-edge connector on the bottom. The

correct position to insert an SFP+ into the upper row of ports is with the gold edge down. The correct position to insert an SFP+ into the lower row of ports is with the gold edge up.

Complete the following steps to install 16 Gbps SFP+ transceivers and cables.

1. Remove any protector plugs from the 16 Gbps SFP+ transceiver and the cable.

2. Position a cable so that the key (the ridge on one side of the cable connector) is

aligned with the slot in the transceiver. Insert the cable into the transceiver until the latching mechanism clicks.

Attention: Take care not to bend the SFP+ pull tab. Do not insert a cable intended for an mSFP transceiver into a regular SFP+ transceiver. You may damage the cable.

3. Transceivers are keyed so that they can only be inserted with the correct orientation. Insert the cable/transceiver into the port, using the pull tab to help push the transceiver into the port. If it does not slide in easily, ensure that it is correctly oriented.

Chapter 2. Installing and configuring the switch 19

mappings or change this mapping using command line interface (CLI) or Web Tools, after you configure an IP address using instructions in “Setting the switch IP address” on page 15.

v Access Gateway simplifies SAN deployment by using N_Port ID Virtualization

(NPIV). NPIV provides Fibre Channel switch functions that improve switch scalability, manageability, and interoperability. For more information on Access Gateway, refer to the following:

– For a list of F_Ports mapped to N_Ports by default, refer to “Access Gateway

default port mapping” on page 40.

– For general information and details on using Access Gateway, refer to the

Access Gateway Administrator’s Guide.

– For specific instructions to prepare the edge fabric before connecting it to

Access Gateway (since Access Gateway relies on NPIV technology for its connection to the edge fabric), refer to the Access Gateway Administrator’s Guide

Note: Access Gateway cannot be connected directly into an array. It requires a

fabric to support NPIV.

v Fabric OS features available to the switch depend on whether the switch is

configured in Access Gateway or Fabric OS Native mode. For a list of available features for each mode, refer to the Access Gateway Administrator’s Guide.

v In Access Gateway mode, cascading is not available for the SAN48B-5. Refer to

the latest Access Gateway Administrator’s Guide for details on any other restrictions specific to the SAN48B-5.

v In Fabric OS Native mode, the switch provides up to eight external Fibre

Channel ports. These universal and self-configuring ports are capable of becoming one of the following port types:

– F_Port (fabric enabled) – FL_Port (fabric loop enabled) – E_Port (expansion port) – M_Port (mirror port)

v In Access Gateway mode, the switch also provides up to eight external Fibre

Channel ports. However, these ports are configured as N_Ports, and you cannot reconfigure these as any other port type.

Disabling and enabling Access Gateway mode

This section provides steps to disable and enable Access Gateway mode using Fabric OS commands. For more information on using these commands, refer to the “Enabling and disabling Access Gateway mode” section in the Access Gateway Administrator’s Guide or the Fabric OS Administrator’s Guide.

Note: You can also disable and enable Access Gateway mode using Web Tools. See

the Web Tools Administrator’s Guide for more information.

Enabling Access Gateway mode

Note the following when enabling Access Gateway (AG) mode:

Chapter 2. Installing and configuring the switch 21

v After you enable AG mode, some fabric information is erased, such as the zone

and security databases.

v Enabling AG mode is disruptive because the switch is disabled and rebooted. v Ensure that no zoning or Admin Domain (AD) transaction buffers are active. If

any transaction buffer is active, enabling Access Gateway mode will fail with the error, “Failed to clear Zoning/Admin Domain configuration.”

Use the following steps to enable Access Gateway mode using Fabric OS commands. For more information on enabling Access Gateway mode, refer to “Enabling and disabling Access Gateway mode” in the Access Gateway Administrator’s Guide.

1. Before disabling a switch to enable Access Gateway mode, save the current configuration file using the configUpload command in case you need this configuration again.

2. 2. Enter the switchShow command to verify the switch mode. v Access Gateway Mode displays for switchMode if the switch is in Access

Gateway mode.

v Native displays for switchMode if the switch is in Fabric OS Native mode.

3. Enter switchDisable to disable the switch. Access Gateway mode can only be enabled or disabled when the switch is in a disabled state.

4. Enter ag –modeEnable to enable Access Gateway mode.

5. Enter the ag --modeShow command to verify that AG mode is enabled.

switch:admin> ag --modeshow Access Gateway mode is enabled.

Disabling Access Gateway mode

When you disable Access Gateway mode, the switch automatically reboots and comes back online using the fabric switch configuration. The Access Gateway parameters, such as F_Port-to-N_Port mapping, Failover, and Failback are automatically removed. When the switch reboots, it starts in Fabric OS Native mode. To re-join the switch to the core fabric, refer to the Access Gateway Administrator’s Guide.

Use the following steps to disable Access Gateway mode using Fabric OS commands. For more information, refer to the “Enabling and disabling Access Gateway mode” section in the Access Gateway Administrator’s Guide.

1. Enter the switchShow command to verify the switch mode.

v “Access Gateway Mode” displays if the switch is in Access Gateway mode. v Interopmode “0” or “Native” displays if the switch is in Fabric OS Native

mode.

2. Enter switchDisable to disable the switch. Access Gateway mode can only be disabled or enabled when the switch is in a disabled state.

3. Enter ag --modeDisable to disable Access Gateway mode.

4. Enter the ag --modeShow command to verify that AG mode is disabled.

Chapter 3. Using and maintaining the switch

This chapter provides information about operating and maintaining the switch and includes these topics.

v “Powering the switch on and off” v “Interpreting LEDs” v “POST and boot specifications” on page 26 v “Interpreting POST results” on page 27 v “SAN48B-5 maintenance” on page 27 v “SAN48B-5 management” on page 28

Powering the switch on and off

Complete the following steps to power the switch on.

1. Connect both power cords to the power connectors on the power supplies and to separate power sources.

2. Set the AC power switches to “|”. Power is supplied to the switch as soon as the first power supply is connected

and powered on. The switch runs POST by default each time it is powered on; it can take several

minutes to boot and complete POST. .

To power the switch off, power off both power supplies by setting each AC power switch to “O”. All devices are returned to their initial state the next time the switch is powered on.

Attention: Power is still supplied to the switch if either of the two power cords are connected. To fully remove power from the switch, both power cords must be disconnected.

Interpreting LEDs

System activity and status can be determined through the activity of the LEDs on the switch.

There are three possible LED states: no light, a steady light, and a flashing light. Flashing lights may be slow, fast, or flickering. The lights are green or amber.

Sometimes, the LEDs flash either of the colors during boot, POST, or other diagnostic tests. This is normal; it does not indicate a problem unless the LEDs do not indicate a healthy state after all boot processes and diagnostic tests are complete.

LED locations

The port side of the switch has the following LEDs (see Figure 11 on page 24).

v One system status LED (above) on the left side v One power LED (below) on the left side v Two Ethernet Port LEDs (both green)

v The serial console port LEDs do not light up at any time, even when a cable is

inserted and the link is active

v One bicolor (green/amber) port status LED for each port on the switch. These

LEDs are arrayed above each pair of Fibre Channel ports.

Figure 11 shows the LEDs on port side of the switch.

POST and boot specifications

When the switch is turned on or rebooted, the switch performs POST. Total boot time with POST can be several minutes. POST can be omitted after subsequent reboots by using the fastboot command or entering the diagDisablePost command to persistently disable POST.

For more information about these commands, refer to the Fabric OS Command Reference Manual.

POST

Boot

The success or failure results of the diagnostic tests that run during POST can be monitored through LED activity, the error log, or the command line interface.

POST includes the following tasks:

1. Conducts preliminary POST diagnostics.

2. Initializes the operating system.

3. Initializes hardware.

4. Runs diagnostic tests on several functions, including circuitry, port

functionality, memory, statistics counters, and serialization.

In addition to POST, boot includes the following tasks after POST is complete:

1. Performs universal port configuration.

2. Initializes links.

3. Analyzes fabric. If any ports are connected to other switches, the switch

participates in a fabric configuration.

4. Obtains a domain ID and assigns port addresses.

5. Constructs unicast routing tables.

6. Enables normal port operation.

26 SAN48B-5 Installation, Service, and User Guide

Interpreting POST results

POST is a system check that is performed each time the switch is powered on, rebooted, or reset. During POST, the LEDs flash either amber or green. Any errors that occur during POST are listed in the error log.

Complete the following steps to determine whether POST completed successfully and whether any errors were detected.

1. Verify that the switch LEDs indicate that all components are healthy. See Table 4 on page 25 and Table 5 on page 26 for descriptions and

interpretations of LED patterns. If one or more LEDs do not display a healthy state, verify that the LEDs on the switch are not set to “beacon” by entering the switchShow command to detect if beaconing is active.

2. Verify that the switch prompt displays on the terminal of a computer workstation connected to the switch.

If there is no switch prompt when POST completes, press Enter. If the switch prompt still does not display, try opening a Telnet session or accessing the switch through another management tool. If this is not successful, the switch did not successfully complete POST. Contact IBM.

3. Review the switch system log for errors. Any errors detected during POST are written to the system log, accessible through the errShow command.

For information about all referenced commands, and on accessing the error log, refer to the Fabric OS Administrator’s Guide. For information about error messages, refer to the Fabric OS Message Reference Manual.

SAN48B-5 maintenance

The SAN48B-5 is designed for high availability and low failure; it does not require any regular physical maintenance. It includes diagnostic tests and field-replaceable units, described in the following sections.

Diagnostic testing

In addition to POST, the Fabric OS includes diagnostic tests to troubleshoot the hardware and firmware. This includes tests of internal connections and circuitry, fixed media, and the transceivers and cables.

The tests are implemented by command, either through a Telnet session or through a terminal set up for a serial connection to the switch. Some tests require the ports to be connected by external cables, to allow diagnostics to verify the serializer/deserializer interface, transceiver, and cable. Some tests require loopback plugs.

Diagnostic tests are run at link speeds of 2, 4, 8, 10 or 16 Gbps (FC) depending on the speed of the link being tested and the type of port.

Note: Diagnostic tests might temporarily lock the transmit and receive speed of

the links during diagnostic testing.

For information about specific diagnostic tests, see the Fabric OS Troubleshooting and Diagnostics Guide.

Chapter 3. Using and maintaining the switch 27

SAN48B-5 management

You can use the management functions built into the SAN48B-5 to monitor the fabric topology, port status, physical status, and other information to help you analyze switch performance and to accelerate system debugging.

The switch automatically performs power-on self-test (POST) each time it is turned on. Any errors are recorded in the system error log. For more information about POST, see “POST and boot specifications” on page 26.

For information about upgrading the version of Fabric OS installed on your switch, see the Fabric OS Administrator’s Guide. You can manage the switch using any of the management options listed in Table 6. Please refer to the Fabric OS Command

Reference Manual for more information on the CLI commands. NTD: are all these valid for IBM version switch?

Chapter 4. FRU replacement

Attention: Read “Safety notices and labels” on page xiii before removing or installing any components.

The field replaceable units (FRUs) in the SAN48B-5 can be removed and replaced without special tools. The switch can continue operating during many of the FRU replacements if the conditions specified in the procedure are followed.

Replacing a power supply and fan assembly

The SAN48B-5 fans are fixed inside the combined power supply and fan FRU to provide necessary airflow to cool the whole system. There are two fans located in each FRU. The system software sets fan speed and measures their speeds through the tachometer interface. The airflow in the SAN48B-5 is from the port side (intake) through the switch to the non-port side (exhaust).

The two power supply and fan assembly FRU units are hot-swappable if replaced one at a time. They are identical and fit into either slot.

Attention: A new FRU must have the same part number (P/N) as the FRU being replaced. The manufacturing P/N is located on the top of the FRU. If a mismatched power source or fan assembly is installed by mistake, a warning is sent to the console. The warning messages will be similar to the following:[WARNING, BR6510, MISMATCH in PSU-FAN FRUS Air Flow direction.

Replace PSU with fan air flows in same direction.

Each power supply/fan assembly has an exhaust airflow label on the faceplate to indicate that the assembly exhausts air (see Figure 13) out the non-port side of the switch.

AIRFLOW

Figure 13. Exhaust airflow label

The E symbol indicates an exhaust FRU. This unit pulls air in from the port side of the switch and exhausts it out the non-port side. This is generally referred to as non-port side exhaust airflow. This is reported as Reverse airflow by the chassisShow command.

See the samples below for the Fan Direction values in the chassisShow output

Fibre Channel port specifications

The Fibre Channel ports in the SAN48B-5 are compatible with SWL, LWL, and ELWL SFP+ (for 16 Gbps performance) transceivers. The strength of the signal is determined by the type of transceiver in use.

The ports meet all required safety standards. For more information about these standards, see “Electronic emission notices” on page 44.

The ports are capable of operating at 2, 4, 8, or 16 Gbps depending on SFP+ models and are able to autonegotiate to the maximum link speed.

Serial port specifications

The serial port is located on the port side of the switch. The switch uses an RJ45 connector for the serial port. An RJ45 to DB9 adaptor cable is also provided with the switch.

Note: To protect the serial port from damage, keep the cover on the port when not

in use.

The serial port can be used to connect to a workstation to configure the switch IP address before connecting the switch to a fabric or IP network. The serial port’s parameters are fixed at 9600 baud, 8 data bits, and no parity, with flow control set to None.

Table 15 lists the serial cable pinouts.
