Avoiding Problems When Inserting and Removing Modules
The ejector levers on the supervisor engine and switching modules align and seat the module connectors
in the backplane (see
Figure 7-5 ). Failure to use the ejector levers to insert the module can disrupt the
order in which the pins make contact with the backplane. Follow the installation and removal instructions
carefully.
When removing a module, use the ejector levers to ensure that the module connector pins disconnect
from the backplane properly. Any supervisor engine or switching module that is only partially connected
to the backplane can disrupt the system. Detailed instructions for removing and installing switching
modules are described in the Catalyst 5000 Series Module Installation Guide.

Tools Required
Use a flat-blade screwdriver to remove any filler (blank) modules and to tighten the captive installation
screws that secure the modules in their slots. When you handle modules, use an ESD-preventive wrist
strap or other grounding device to prevent electrostatic discharge (ESD) damage.
Removing the Supervisor Engine
Before you remove a supervisor engine, you should first upload the current configuration to a server.
This saves time when bringing the module back online. You can recover the configuration by
downloading it from the server to the nonvolatile memory of the supervisor engine.
To remove a supervisor engine, perform the following steps:
Step 1 If you do not plan to immediately reinstall the supervisor engine you are removing, disconnect any
network interface cables attached to the module ports.
Step 2 Use a screwdriver to loosen the captive installation screws at the left and right sides of the module.
Step 3 Grasp the left and right ejector levers and simultaneously pull the left lever to the left and the right lever
to the right to release the module from the backplane connector.
