Installation and safety considerations

The 8Gb SAN Switch installs in the I/O bays in the rear of the HP BladeSystem c-Class enclosure. Refer to the appropriate BladeSystem Enclosure Setup and Installation Guide for specific enclosure requirements.

Installing multiple switches

If you do not have a DHCP server connected to the OA, install and configure one 8Gb SAN Switch at a time. This is required so that Ethernet IP address conflicts do not occur with duplicate default Ethernet IP addresses.

IMPORTANT:

DHCP is enabled by default on this switch. In cases where DHCP is available, IP address conflicts will not occur, simplifying multiple switch installations. See Using external DHCP, page 24.

Each switch must be assigned a unique Ethernet IP address during configuration. Once the default Ethernet IP address on the 8Gb SAN Switch has been changed, you may install additional 8Gb SAN Switches in the enclosure.

See the appropriate HP BladeSystem Enclosure Setup and Installation Guide for help identifying your specific enclosure setup, available connections, and power requirements.

Electrical considerations

The 8Gb SAN Switch requires 35 watts, provided by the enclosure. No other power requirement or provision exists.

Environmental considerations

Ensure proper cooling and ventilation by verifying the following:

• The air vents on the enclosure are not blocked or restricted.

• The ambient air temperature at the front of the enclosure does not exceed 35°C (95°F) while the

switch is operating.

IMPORTANT:

The dust covers that ship with your 8Gb SAN Switch not installed, to help contain air flow in the BladeSystem chassis.

must

be inserted into any ports where SFPs are

Install the 8Gb SAN Switch

Install the Brocade 8Gb SAN Switch into the enclosure:

Setup20

1. Locate the appropriate interconnect bay in the rear of the enclosure as specified in the appropriate

HP BladeSystem Enclosure Setup and Installation Guide provided with your enclosure.

OA power verification

As defined earlier, the HP BladeSystem Onboard Administrator (OA) is the enclosure management processor that manages the devices contained within the enclosure. The OA provides a single point from which to perform basic management tasks on switches or server blades installed in the enclosure.

IMPORTANT:

HP recommends reading the appropriate

BladeSystem Onboard Administrator User Guide

overall understanding of your specific enclosure model.

Once the switch is installed in the interconnect bay, the OA verifies that the switch type matches the mezzanine cards present on the servers. If there is no mismatch, the OA powers up the switch.

If the switch does not power up, check the enclosure and switch status with the OA web interface. Refer to the HP BladeSystem Onboard Administrator User Guide.

Using Dynamic Ports On Demand (DPOD)

DPOD functionality does not require a predefined assignment of ports. Port assignment is determined by the total number of ports in use as well as the number of purchased ports.

In summary, the DPOD feature simplifies port management by:

• Automatically detecting HBA connected server ports or cabled ports

• Automatically enabling ports

• Automatically assigning port licenses

To initiate DPOD, use the licensePort command, as described in DPOD commands, page 29.

IMPORTANT:

For the Brocade 8Gb SAN Switch, DPOD works only if the server blade is installed with an HBA present. A server blade that does not have a functioning HBA will not be treated as an active link for the purpose of initial POD port assignment.

DPOD commands

Use the licensePort command to manage dynamic POD assignments with the following options:

• licensePort –reserve portnum reserves a future license assignment for a specific port,

even if the port is currently offline.

• licensePort –release portnum removes a license from a port.

• portCfgPersistentDisable blocks a specific port from future assignments.

• licensePort -show displays an overview of the POD license status and port assignments.

The following shows examples of the licensePort -show command for a Brocade 8/12 SAN Switch and a Brocade 8/24 SAN Switch:

Example for Brocade 8/12 SAN Switch

For information about specific diagnostic tests, refer to the latest version of the HP StorageWorks Fabric OS administrator guide, or enter help followed by the name of the diagnostic test.

Brocade 8Gb SAN Switch for HP BladeSystem c-Class 35

Powering on and off

8Gb SAN Switch power is provided by the enclosure. The 8Gb SAN Switch runs POST by default each time power to the enclosure is turned on. The POST process can last as long as three minutes.

To remove power from the switch, remove the 8Gb SAN Switch from the enclosure interconnect bay.

NOTE:

Each time the 8Gb SAN Switch is powered on, its settings are restored to the last saved configuration.

Interpreting LED activity

You can monitor switch activity and status by checking 8Gb SAN Switch LEDs.

There are three possible LED states: no light, a steady light, or a flashing light. The steady lights and flashing lights can be green or amber.

The LEDs flash any of these colors during boot, POST, or other diagnostic tests. This is normal and does not indicate a problem unless the LEDs do not indicate a healthy state after all boot processes and diagnostic tests are complete. A healthy state is indicated by a steady green light. See Table

15, page 37 for details about LED activity.

LED indicators

All 8Gb SAN Switch LEDs are located on the port side. See Figure 8 and Table 14.

POST and boot specifications

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

The 8Gb SAN Switch performs POST when it is turned on or rebooted. Total boot time with POST is approximately three minutes.

POST can be omitted for subsequent reboots by using the fastboot command. For more information about this command, refer to the latest version of the Fabric OS command reference guide. If you suspect a problem with the switch, enable POST to obtain more information on any failure.

Port is disabled as a result of diagnostics or portDisable command. If the LEDs for all ports are slow-flashing amber, the switch could be disabled.

Port is faulty.

Enable the port using the portEnable com- mand; If the LEDs for all ports are slow-flashing amber, enable the switch by entering the switchEnable command.

Check the Port Status LEDs, error log, transceiv- er, and cable or loopback plug. Clear the error log. Rerun the diagnostics to verify that the er- ror condition is fixed.

Check configuration of FC loop.Port is bypassed.

POST

Boot

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

POST includes the following steps:

• Preliminary POST diagnostics are run.

• Operating system is initialized.

• Hardware is initialized.

• Diagnostic tests are run on several functions, including circuitry, port functionality, memory, statistics

counters, and serialization.

Boot completes in approximately three minutes if POST is run. Boot includes the following tasks after POST completes:

• Universal port configuration

• Links initialized

• Fabric is analyzed; if any ports are connected to other switches, the 8Gb SAN Switch participates

in a fabric configuration

• The 8Gb SAN Switch obtains a domain ID and assigns port addresses

• Unicast routing tables constructed

• Normal port operation enabled

Managing the 8Gb SAN Switch38

Interpreting POST results

To determine whether POST completed successfully and whether any errors were detected:

1. Verify that the 8Gb SAN Switch LEDs indicate all components are healthy. See Table 16, page

37 for description and interpretation of LED patterns. If one or more LEDs do not display a Healthy state, use the switchshow command to verify that the LEDs on the switch are not set to “beacon”.

2. Verify that the 8Gb SAN Switch prompt appears 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 appear, try opening another Telnet session or another management tool. If this is not successful, the 8Gb SAN Switch did not successfully complete POST; contact HP.

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 accessing the error log, refer to the latest version of the HP StorageWorks Fabric OS administrator guide. For information about error messages, refer to the Fabric OS system error messages reference manual.

B Electrostatic discharge

This appendix provides the following information:

• How to prevent electrostatic discharge, page 49

• Grounding methods, page 49

How to prevent electrostatic discharge

To prevent damage to the system, you must follow certain precautions when setting up the system or handling parts. A discharge of static electricity from a finger or other conductor may damage system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the device.

To prevent electrostatic damage, observe the following precautions:

• Avoid hand contact by transporting and storing products in static-safe containers.

• Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations.

• Place parts on a grounded surface before removing them from their containers.

• Avoid touching pins, leads, or circuitry.

• Always make sure you are properly grounded when touching a static-sensitive component or as-

sembly.

Grounding methods

There are several methods for grounding. Use one or more of the following methods when handling or installing electrostatic-sensitive parts:

• Use a wrist strap connected by a ground cord to a grounded workstation or chassis. Wrist straps

are flexible straps with a minimum of 1 megohm ± 10 percent resistance in the ground cords. To provide proper ground, wear the strap snug against the skin.

• Use heel straps, toe straps, or boot straps at standing workstations. Wear the straps on both feet

when standing on conductive floors or static-dissipating floor mats.

• Use conductive field service tools.

• Use a portable field service kit with a folding static-dissipating work mat.

If you do not have any of the suggested equipment for proper grounding, have an HP authorized reseller install the part.

NOTE:

For more information on static electricity, or for assistance with product installation, contact your HP authorized reseller.
