Figure 4-24 Removing a Line Card
Step 1 Attach the ESD-preventive wrist strap to your wrist and connect its leash to an ESD connection socket
on the rear (MSC) side or a bare metal surface on the chassis.
Step 2 Use a screwdriver to loosen the captive screw next to each MSC ejector lever.
Caution To prevent ESD damage, handle a line card by its ejector levers or the card carrier edges only.
Do not touch any of the electrical components, pins, or circuitry.
Step 3 Simultaneously pivot the ejector levers away from the faceplate to release the line card from the
midplane connectors.
Step 4 Grasp the cable management bracket and gently pull the line card halfway from the slot.
Step 5 Move one hand under the line card to guide it.
Avoid touching the line card printed circuit board, components, or any connector pins. Do not lift cards
by the cable management bracket—lift the cards from the bottom, using the cable management bracket
only as an aid for balance.
