POST and boot specifications
POST is a system check performed each time the switch is powered on, rebooted, or reset. During
POST, the LEDs flash different colors. Any errors that occur during POST are listed in the error log.
The 8Gb SAN Switch performs POST when it is turned on or rebooted. Total boot time with POST
is approximately three minutes.
