Removing the Network Processing Engine

Removing the NPE or NSE-1

To remove the NPE or NSE-1 from a Cisco 7200 VXR router, a Cisco uBR7246VXR or a Cisco UBR7225VXR router complete the following steps.

Note The weight of installed power supplies in your Cisco 7200 VXR or Cisco uBR7246VXR router might make it difficult to remove the network processing engine. If you have difficulty, first remove the power supplies from the chassis, and then remove the network processing engine. See the “Removing and Replacing an AC-Input or DC-Input Power Supply” section on page 10-14for information on removing and replacing an installed power supply.

Note If you have difficulty installing a network processing engine or I/O controller in the lowest slot of a Cisco 7200 VXR router that is rack-mounted, remove the port adapters, network processing engine and I/O controller from the chassis and reinstall them. Install the network processing engine and I/O controller in the lowest slots first, then populate the slots above them, in a bottom-to-top order.

Step 1 Power down the router and disconnect the input power cable. (See the “Powering Down the Router and Disconnecting Input Power” section on page 7-8.)

Step 2 Attach an ESD-preventive wrist strap between you and an unfinished chassis surface.

Step 3 Using a number 2 Phillips or a 3/16-inch flat-blade screwdriver, loosen the two captive installation screws on the faceplate of the network processing engine. (See Figure 7-6.)

If the router is not installed in a standard 19-inch, 4-post or telco-type rack, skip to Step 7. If the router is installed in a rack, determine if any permanent rack fixtures, such as a power strip, are obstructing access to the rear of the router. If a rack fixture is obstructing access to the router, proceed with Step 4.
