Step 3 Check the field Number of Switch Cards present in the Chassis. If you only have two switch processors,
your switch router does not have EHSA. With three switch processors installed, if either of the two active
switch processors fail, the third processor takes over.
Step 4 Check the SWC_STATUS field. This fields identifies the active and standby switch processors.
If you determine that redundancy is configured incorrectly, refer to the “Initially Configuring the
ATM Switch Router” chapter in the ATM Switch Router Software Configuration Guide.
