to within the threshold limits in 120 seconds, the switch powers off and the power supplies must be

Expansion Module Diagnostics

During the switch bootup or reset, the bootup diagnostics include tests for the in-service expansion modules

in the switch.

When you insert an expansion module into a running switch, a set of diagnostics tests are run. The following

table describes the bootup diagnostics for an expansion module. These tests are common with the bootup

diagnostics. If the bootup diagnostics fail, the expansion module is not placed into service.
