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

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.

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.

Management features
The management tools built into the 8Gb SAN Switch (listed in Table 11) can be used to monitor
fabric topology, port status, physical status, and other information used for performance analysis and
system debugging.
When running IP over FC, these management tools must be run on both the Fibre Channel host and
the switch and must be supported by the Fibre Channel host driver. For a list of Fibre Channel hosts
supported by the 8Gb SAN Switch, contact your HP representative.

For information about specific diagnostic tests, refer to the latest version of the HP StorageWorksFabric OS administrator guide, or enter help followed by the name of the diagnostic test.
Brocade 8Gb SAN Switch for HP BladeSystem c-Class35
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 portEnablecom-
mand; If the LEDs for all ports are slow-flashing
amber, enable the switch by entering theswitchEnable command.
Check the Port Status LEDs, error log, transceiv-
er, and cable or loopback plug. Clear theerror
log. Rerun the diagnostics to verify thattheer-
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.

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.
