Removing and Replacing an EPA

The online insertion and removal (OIR) feature allows you to install and replace an Ethernet port adapter
(EPA) while the router is operating. You do not have to shut down the system’s power, although you should
not run traffic through the EPA while it is being removed. OIR is a method that is seamless to end users on
the network, maintains all routing information, and preserves sessions.

As you disengage the EPA from the router, OIR shuts down all the active interfaces in the EPA.

Note

For detailed information about EPA software commands, such as preparing for OIR of EPAs, and activating
and deactivating configuration examples, see the

Cisco ASR 1000 Series Modular Interface Processor

Installation Guide

.

Note

We suggest you have the following tools and parts readily available for installing an EPA:

• Number 2 Phillips or a 3/16-inch flat-blade screwdriver

• EPA or blank filler plate (EPA-BLANK=)

• Any SFP modules that you have to install (and have not already installed)

• Cables

• Your own ESD-prevention equipment or the disposable grounding wrist strap included with all upgrade

kits, field-replaceable units (FRUs), and spares

• Antistatic mat or surface, or static shielding bag

If you need additional equipment, contact a service representative for ordering information.

Electrostatic Discharge Prevention

Electrostatic discharge (ESD) damages equipment and impairs electrical circuitry. ESD occurs when printed
circuit boards are improperly handled and results in complete or intermittent failures.

Each EPA circuit board is mounted to a metal carrier and is sensitive to ESD damage. an EPA consists of a
printed circuit board that is fixed in a metal carrier. Electromagnetic interference (EMI) shielding, connectors,
and a handle are integral components of the carrier.

When the subslot is not in use, an EPA blank filler plate must fill the empty subslot to allow the router to
conform to EMI emission requirements and to allow proper airflow across the installed modules. If you plan
to install the EPA in the subslot that is not in use, you must first remove the EPA blank filler plate.
