POST and boot specifications
When the switch is turned on (plugged in) or rebooted, the switch performs POST.
Total boot time with POST is a minimum of 3 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 Brocade Fabric OS Command
Reference Manual .
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:
1. Preliminary POST diagnostics are run.
2. Operating system is initialized.
3. Hardware is initialized.
4. Diagnostic tests are run on several functions, including circuitry, port
functionality, memory, statistics counters, and serialization.
Boot
Boot completes in a minimum of 3 minutes if POST is run. In addition to POST,
boot includes the following steps after POST is complete:
1. Universal port configuration is performed.
2. Links are initialized.
3. Fabric is analyzed, and if any ports are connected to other switches, the switch
participates in a fabric configuration.
4. Switch obtains a domain ID and assigns port addresses.
5. Unicast routing tables are constructed.
6. Normal port operation is enabled.
