Urgent "Failover" to redundant core switch @ 2am

A probable bug in the Cisco IOS running on the current active layer 3 core switch is preventing us from remotely managing the device. We have exhausted the options for restoring the functionality without interrupting the traffic flow through it.
Tonight, after 02:00 PDT we will force the redundant layer 3 core switch to take over while we address the issue with the current primary switch. The cut-over to the redundant switch should only take a few seconds. If we fail-back to the current primary within a short time, it too should only take a few seconds.

Date/Time: Thursday 8/21/08 @ 02:00 US/Pacific (GMT -7)
Duration: 5 to 30 seconds (1 minute "worst case")
