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 4Gb 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 4Gb SAN
Switch participates in a fabric configuration
