Installing And Removing Modular Port Adapters; Handling Modular Port Adapters - Cisco ASR 9000 Series Installation Manual

Installing and Removing Modular Port Adapters

Caution
To ensure adequate space for additional MLCs always tighten the captive installation screws on each newly
installed MLC before you insert any additional MLCs. These screws also prevent accidental removal and
provide proper grounding and EMI shielding for the router.
7. Install the MPAs and SFP modules in the MPAs that use them. See
Port Adapters, on page
8. If you are replacing a MLC, install the MPA in the same bays as you noted in Step 2 under
Line Card, on page
9. Install the interface cables.
Installing and Removing Modular Port Adapters
The following sections describe how to install or remove MPA on the Cisco ASR 9000 Series Aggregation
Services Router.

Handling Modular Port Adapters

Each modular port adapter (MPA) circuit board is mounted to a metal carrier and is sensitive to electrostatic
discharge (ESD) damage.
Caution Always handle the MPA by the carrier edges and handle; never touch the MPA components or connector pins
(See the figure below).
When a bay is not in use, a blank 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 MPA in a bay that is not in use, you must first
remove the blank.
