Diagnostic Commands

Every time that the SilkWorm 12000 powers up it runs POST (Power On Self Test), the switch runs a
series of diagnostic tests to determine the health of the switch and each of its components. This process
takes approximately ten minutes to run POST with eight (8) 16-port cards inserted. In order to disable
POST diagnostics, the user can execute diagdisablepost (or diagenablepost to re-enable). This will allow
the chassis to be rebooted in a more timely manner, but should not be disabled during normal operations.
