Access Controller xl Module for the Series 5300xl Switches

BIOS POST Event Log Messages

If a critical BIOS power on self test (POST) failure occurs when the ACM is

inserted into a slot in a 5300xl chassis, the message below is posted to the

Event Log. The 5300xl switch resets the ACM, up to two times (a total of three

attempts to pass the POST). If the ACM fails three consecutive times, the

module does not power on. The 5300xl switch can operate successfully if this

occurs.
