POST and boot specifications
When the switch is turned on or rebooted, the switch performs POST. Total boot time with POST can
be several 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 Fabric OS Command Reference Manual .
POST
The success or 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 tasks:
1. Conducts preliminary POST diagnostics.
2. Initializes the operating system.
3. Initializes hardware.
4. Runs diagnostic tests on several functions, including circuitry, port functionality, memory, statistics
counters, and serialization.
