Considerations for Replacing SSMs and Supervisor Modules If you replace an SSM or supervisor module, you should consider the following: • If you replace an SSM with another SSM and the boot image is on bootflash:, respectively, you can leave the boot image installed on the active supervisor. • If you replace an SSM with another SSM and the SSI boot image is on the modflash:, the SSM might not initialize. See the "Recovering an SSM After Replacing Corrupted CompactFlash Memory" section on page 19-33. • If you replace an SSM with any other module, you can leave the boot image installed on the active supervisor or remove it. The active supervisor module detects the module type and boots the module appropriately. • If you replace a supervisor module in a switch with active and standby supervisors, no action is required because the boot image is automatically synchronized to the new supervisor module. • If you replace a supervisor module in a switch with no standby supervisor, you need to reimplement the configuration on the new supervisor. Default Settings Table 19-9 lists the default settings for the supervisor module. Table 19-9 Default Supervisor Module Settings Parameters Administrative connection Global switch information System clock In-band (VSAN 1) interface Default Serial connection. • No value for system name. • No value for system contact. • No value for location. No value for system clock time. IP address, subnet mask, and broadcast address assigned to the VSAN are set to 0.0.0.0. Table 19-10 lists the default settings for the SSM.
