Network Processing Engine Replacement Instructions 19

Removing and Replacing the Network Processing Engine

The following sections explain how to remove and replace the network processing engine in the

Cisco 7200 series routers or Cisco uBR7200 series routers:

• Powering Down the Router and Disconnecting Input Power, page 19

• Removing the Network Processing Engine, page 24

• Replacing the Network Processing Engine, page 27

• Reconnecting Input Power and Powering Up the Router, page 29

Note If you are installing an NPE-100 or NPE-150, make sure that you replace the boot ROM on

the I/O controller before attempting to boot your router. Refer to the “Software and Hardware

Requirements” section on page 12 for network processing engine installation requirements.

This note does not apply to the Cisco uBR7200 series or to the Cisco AS5800 Universal Access

Server router shelf.

Note Make sure that you upgrade the Flash SIMM on any previously purchased I/O controller

before attempting to boot a Cisco 7200 VXR router that has a newly installed NPE-300. Instructions

for replacing the Flash SIMM are found in the Memory Replacement Instructions for the Network

Processing Engine and Input/Output Controller document that shipped with your NPE-300.

Note The procedures for removing and replacing a network processing engine are the same for all

Cisco 7200 series routers, including the Cisco 7206 and Cisco 7206VXR when used as router

shelves in the Cisco AS5800 Universal Access Server. Therefore, the illustrations and procedures in

the following sections apply to the Cisco 7200 series routers and the Cisco AS5800 Universal

Access Server router shelves unless indicated otherwise.

There are separate illustrations for the network processing engine and the Cisco uBR7200 series

routers.

Note The NPE-300 is only compatible with the Cisco 7200 VXR routers; the NPE-300 is keyed to

prevent insertion in Cisco 7200 routers (7202, 7204, 7206).

Powering Down the Router and Disconnecting Input Power

Complete the steps in the following sections to power down the router and disconnect input power.

Warning This unit might have more than one power cord. To reduce the risk of electric shock,

disconnect the two power cords before servicing.
