POST and boot specifications
When the switch is turned on or rebooted, the switch performs a power-on, self-test (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 no diag post command to persistently disable POST.
For more information about these commands, refer to the Brocade Network OS Command
Reference.

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 tasks:
• Conducts preliminary POST diagnostics.
• Initializes the operating system.
• Initializes hardware.
• Runs diagnostic tests on several functions, including circuitry, port functionality, memory,
statistics counters, and serialization.
