Removing and Installing a Line Card
Caution When you remove a line card, always use the ejector levers to ensure that the line card connector pins
disconnect from the backplane in the logical sequence expected by the router. Any line card that is only
partially connected to the backplane can halt the router.
Step 5 Simultaneously pivot the ejector levers away from each other to release the line card from the backplane
connector. (See Figure 10b.)
Step 6 Grasp the ejector levers and pull the line card halfway out of the slot.
Step 7 Grasp the line card and gently pull it straight out of the slot, keeping your other hand under the line card
to guide it. (See Figure 10c.) Avoid touching the line card printed circuit board, components, or any
connector pins.
Step 8 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 9 If the line card slot is to remain empty, install a line card blank (Product Number MAS-GSR-BLANK)
to keep dust out of the chassis and to maintain proper airflow through the line card compartment. Secure
the line card blank to the chassis by tightening its captive screws.
Installing a Line Card
A line card slides into almost any available line card slot and connects directly to the backplane. If you
install a new line card, you must first remove the line card blank from the available slot.
Note Refer to the installation and configuration guide for your router for information on line card slot types,
slot width, and slot location.
Caution The router may indicate a hardware failure if you do not follow proper procedures. Remove or insert only
one line card at a time. Allow at least 15 seconds for the router to complete the preceding tasks before
removing or inserting another line card.
To install a line card, follow these steps:
Step 1 Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.
Step 2 Choose an available line card slot for the line card, and verify that the line card interface cable is long
enough for you to connect the line card with any external equipment.
Caution To prevent ESD damage, handle line cards 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.
Step 3 Grasp the faceplate (or handle) of the line card 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 line card printed circuit board, components, or any connector pins.
