Chapter 9 Removing and Installing the NPE or NSE
Removing and Replacing the NPE or NSE
Caution Make sure that at least one other person is available to support the front of the router as you slide it out
from the rack and, if necessary, to continue to support it while you remove and insert the power supply,
network processing engine or network services engine, or subchassis.
Removing and Replacing the NPE or NSE
The procedures for removing and replacing an NPE or NSE 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. The procedures are also the same for the Cisco uBR7246VXR router.
The illustrations and procedures in the following sections apply to the Cisco 7200 series routers or
Cisco uBR7246VXR router and the Cisco AS5800 Universal Access Server router shelves unless
indicated otherwise.
Note The NSE-1 is keyed for insertion in only Cisco 7200 VXR routers. The NSE-1 is not supported on the
Cisco uBR7246VXR universal broadband router, although it can be inserted into the router chassis.
The following sections explain how to remove and install an NPE or NSE-1 in the Cisco 7200 VXR
routers or Cisco uBR7246VXR router:
Powering Down the Router and Disconnecting Input Power, page 9-2

Note When installing an NPE-175, NPE-225, NPE-300, NPE-400, or NSE-1 in a Cisco 7200 VXR router that
is using a previously purchased I/O controller, you must upgrade the I/O controller boot helper image.
Instructions for upgrading the boot helper image on the I/O controller are contained in the online
Memory Replacement Instructions for the Network Processing Engine or Network Services Engine and
Input/Output Controller publication.

Powering Down the Router and Disconnecting Input Power

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