• Place a removed component board-side-up on an antistatic surface or in a static shielding container. If you plan to return the
component to the factory, immediately place it in a static shielding container.
• Avoid contact between the printed circuit boards and clothing. The wrist strap only protects components from ESD voltages
on the body; ESD voltages on clothing can still cause damage.
• Never attempt to remove the printed circuit board from the metal carrier.

To prevent ESD damage, handle supervisor engines by the carrier edges only.
Caution
Before You Begin
You will need a blank module filler plate if the module slot is to remain empty.
Procedure
Step 1
Take the necessary precautions, to prevent ESD damage. Wear a grounded ESD wrist strap while handling the modules,
and keep them in ESD-protective bags when they are not installed in a chassis.
Step 2
Disconnect any network interface cables attached to the ports on the supervisor engine that you intend to remove.
Step 3
If the module is equipped with removable optical transceivers, immediately install dust plugs into the transceiver's optical
bores. This prevents possible dust contamination, which can affect port performance.
Step 4
Loosen the two captive installation screws on either end of the supervisor engine faceplate.
Step 5
Grasp the left and right ejector levers at either end of the supervisor engine faceplate and simultaneously pivot the levers
outward to disengage the supervisor engine from the backplane connector.
Step 6
Grasp the front panel of the supervisor engine with one hand and place your other hand under the carrier to support and
guide it out of the slot. Do not touch the printed circuit boards or connector pins.
Step 7
Carefully slide the supervisor engine straight out of the slot, keeping your other hand under the carrier to guide it.
Step 8
Place the supervisor engine on an antistatic mat or in an antistatic bag, or immediately install the supervisor engine in
another chassis slot.
Step 9
In a chassis configured with redundant supervisor engines, if the chassis slot is to remain empty, you must install a blank
slot cover.
Warning
Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages
and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other
equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all
cards, faceplates, front covers, and rear covers are in place. Statement 1029
