Installing and Removing a Modular Line Card (MLC)
To prevent ESD damage, handle modular line cards (MLCs) by the captive installation screws, the

provided handle, ejector levers, or the card carrier edges only. Do not touch any of the electrical
components or circuitry.
Grasp the handle of the modular line card (MLC) with one hand and place your other hand under the

card carrier to support the weight of the card; position the card for insertion into the card cage slot. Avoid
touching the modular line card (MLC) printed circuit board, components, or any connector pins.
Step 4
Carefully slide the modular line card (MLC) into the slot until the ejector levers make contact with the
edges of the card cage, then stop when the ejector lever hooks catch the lip of the card cage. If they do
not catch, try reinserting the modular line card (MLC) until the ejector lever hooks are fully latched. (See

When you install a modular line card (MLC), always use the ejector levers to ensure that the card is

correctly aligned with the backplane connector, the card connector pins make contact with the backplane
in the correct order, and the card is fully seated in the backplane. A card that is only partially seated in
the backplane can cause the router to hang and subsequently crash.
Simultaneously pivot both ejector levers toward each other until they are perpendicular to the modular
