DETAILED STEPS
Step 1
Attach the ESD-preventive wrist strap to your wrist and connect its leash to one of the ESD connection sockets on the
front (PLIM) side of the chassis or a bare metal surface on the chassis.
Step 2
Use a screwdriver to loosen the captive screw next to each line card ejector lever.
To prevent ESD damage, handle a line card by its ejector levers or the line card carrier edges only. Do not touch
any of the electrical components, pins, or circuitry.
Caution
Step 3
Simultaneously pivot the ejector levers away from the faceplate to release the line card from the midplane connectors.
Step 4
Grasp the ejector levers with both hands and gently pull the line card halfway from the slot. Do not use the bracket to
pull the line card 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.
Step 6
Place the removed line card on an antistatic mat, or immediately place it in an antistatic bag if you plan to return it to the
factory.
Step 7
If the line card slot is to remain empty, install an MSC impedance carrier to keep dust out of the chassis and to maintain
proper airflow through the line card compartment.
Step 8
Use a screwdriver to tighten the captive screws next to each impedance carrier ejector lever to ensure proper EMI shielding
and maintain proper airflow throughout the chassis.
What to do next
After performing this task, put the line card into an antistatic bag and close the rear (MSC) side cosmetic
doors (if installed).
