Replacing the Supervisor Engine
Before you can power up the system, you need to remove the supervisor engine from slot 1 (if a
redundant supervisor engine is present, remove it from slot 2) and install the Supervisor Engine 720 or
the Supervisor Engine 32 in slot 5 or 6.
Removing the Supervisor Engine
This section describes how to remove an existing supervisor engine from a chassis slot.
To remove a supervisor engine from the chassis, perform these steps:
Step 1 Disconnect any network interface cables attached to the supervisor engine.
Step 2 Verify that the captive installation screws on all of the modules in the chassis are tight. This step assures
that the space created by the removed supervisor engine is maintained.
Note If the captive installation screws are loose, the electromagnetic interference (EMI) gaskets on
the installed modules will push the modules toward the open slot, reducing the opening size and
making it difficult to install the replacement module.
