Installing a Modular Line Card
A modular line card (MLC) slides into any available line card slot and connects directly to the backplane. If
you install a new MLC, you must first remove the line card blank from the available slot.
See the Cisco ASR 9000 Series Aggregation Services Router Hardware Installation Guide for information on
line card slot types in order to determine an appropriate slot in which to install the MLC.
Note
The router may indicate a hardware failure if you do not follow proper procedures. Remove or insert only
one MLC at a time. Allow at least 15 seconds for the router to complete the preceding tasks before removing
or inserting another MLC.
Caution
To install a modular line card, follow these steps:
1. Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.
2. Choose an available MLC slot for the card and verify that the MPA interface cables are long enough for
you to connect the MLC with any external equipment.
To prevent ESD damage, handle 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.
Caution
3. Grasp the handle of the 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 MLC
printed circuit board, components, or any connector pins.
4. Carefully slide the 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 MLC until the ejector lever hooks are fully latched (see the figure below).
