HP Brocade 8Gb SAN Switch for HP BladeSystem c-Class - Manual (Page 38)

Recommended action Status of hardware LED color LED name
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.
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.
Slow-flashing amber
(on 1 second, off 1
second)
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.
Port is faulty.
Fast-flashing amber (on
1/2 second, off 1/2

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.
POST
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
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
