Removing the Supervisor Engine or a Module

Caution To prevent ESD damage, handle modules by the carrier edges only.
Warning Hazardous voltage or energy is present on the backplane when the system is operating. Use caution
when servicing.
Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into

beams or view directly with optical instruments.
To remove a supervisor engine or module, perform these steps:
Step 1 Disconnect any network interface cables attached to the supervisor engine or module.
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 module is maintained.
Note
Loosen the two captive screws on the supervisor engine or module.
Step 3
Depending on the position of the slots in the chassis (horizontal or vertical), perform one of these two
Step 4
sets of steps:
Horizontal slots
Place your thumbs on the left and right ejector levers and simultaneously rotate the levers outward
a.
to unseat the module from the backplane connector.
Grasp the front edge of the module and slide the module part of the way out of the slot. Place your
b.
other hand under the module to support the weight of the module. Do not touch the module circuitry.
Vertical slots
Place your thumbs on the ejector levers located at the top and bottom of the module, and
a.
simultaneously rotate the levers outward to unseat the module from the backplane connector.
Grasp the edges of the module, and slide the module straight out of the slot. Do not touch the module
b.
circuitry.
Place the module on an antistatic mat or antistatic foam, or immediately reinstall it in another slot.
Step 5
If the slot is to remain empty, install a module filler plate to keep dust out of the chassis and to maintain
Step 6
proper airflow through the chassis.

If the captive installation screws are loose, the 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.
