Expansion Module Diagnostics
During 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.
