Table 1-3 describes the health monitoring diagnostics that also run during system boot or system reset.
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. Table 1-4
describes the bootup diagnostics for an expansion module. If the bootup diagnostics fail, the expansion
module is not placed into service.
Health monitoring diagnostics are run on in-service expansion modules. Table 1-4 describes the tests
that are common with the bootup diagnostics. Table 1-5 describes the additional tests that are specific to
health monitoring diagnostics for expansion modules.
