Handling Modular Port Adapters (MPAs)

Each modular port adapter (MPA) circuit board is mounted on a metal carrier, and is sensitive to electrostatic discharge (ESD) damage. Before you begin installation, refer to the Preparing to Install Modular Line Cards (MLCs) or Modular Port Adapters (MPAs) section of the Cisco ASR 9000 Series Aggregation Services Router Ethernet Line Card Installation Guide for a list of parts and tools required for installation.

Caution Always handle the modular port adapter (MPA) by the carrier edges and handle; never touch the modular port adapter (MPA) components or connector pins. (See Figure 3-5.)

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.

Online Insertion and Removal

Cisco ASR 9001 Router modular port adapters (MPAs) support online insertion and removal (OIR).

Modular port adapters (MPAs) support three types of OIR:

•Soft OIR

Soft OIR uses the IOS XR hw-module subslot 0/0/1 reload, hw-module subslot 0/0/1 shutdown, and no hw-module subslot 0/0/1 shutdown commands to complete online insertion and removal. Refer to the Hardware Redundancy and Node Administration Commands on the Cisco ASR 9000 Series Router chapter of the Cisco ASR 9000 Series Aggregation Services Router System Management Command Reference online for command syntax.

•Managed OIR

A managed online insertion and removal of Modular port adapters (MPAs) is comprised of these steps:

1.Shut down the MPA with the hw-module subslot 0/0/1 shutdown command.

2.Confirm that the LEDs have gone from green to off.
