POST and boot specifications
The switch performs POST by default each time it is powered on or rebooted or the
system is reset. Boot time with POST is a minimum of three minutes. POST can be
skipped after subsequent reboots by entering the fastBoot command. For more
information about this command, refer to the Fabric OS Command Reference .
POST
The success or failure results of the diagnostic tests that run during POST can be
monitored through LED activity, 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
In addition to POST, boot includes the following steps after POST is complete:
1. Universal port configuration is performed.
