(MLC) faceplate to ensure proper EMI shielding and to prevent the modular line card (MLC) from
becoming partially dislodged from the backplane. Tighten the locking thumbscrews on both sides of the
modular line card (MLC) to a torque of between 8.3 and 11 inch-pounds (94 to 124 N-cm). Do not
overtighten.
To ensure adequate space for additional modular line cards (MLCs), always tighten the captive

installation screws on each newly installed modular line card (MLC) before you insert any additional
modular line cards (MLCs). These screws also prevent accidental removal and provide proper grounding
and EMI shielding for the router.

Handling Modular Port Adapters (MPAs)

Each modular port adapter (MPA) circuit board is mounted to a metal carrier and is sensitive to
electrostatic discharge (ESD) damage. Before you begin installation, read

When a bay is not in use, a blank ASR 9000 MPA Slot Filler (A9K-MPA-FILR) must fill the empty bay
to allow the router or switch to conform to electromagnetic interference (EMI) emissions requirements
and to allow proper airflow across the installed modules. If you plan to install a modular port adapter
(MPA) in a bay that is not in use, you must first remove the blank.
