Cisco Systems NPE-175, NPE-225 manual Installing the NPE or NSE

Chapter 9 Removing and Installing the NPE or NSE

Removing and Replacing the NPE or NSE

SIMMs or DIMMs should be aligned at the same angle and the same height as others on the board when properly installed. If the SIMM, DIMM, or SODIMM appears to stick out or rest in the socket at an odd angle, remove it and reinsert it. Then replace the network processing engine or network services engine and reboot the system for another installation check.

If after several attempts the system fails to restart properly, contact a service representative for assistance. Before you call, note any error messages, unusual LED states, or other indications that might help solve the problem.

Installing the NPE or NSE

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.

To install an NPE or NSE in the router, complete the following steps:

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.

Step 1 Ensure that the router is powered down and the input power cable is disconnected from the router and the power source. See the “Powering Down the Router and Disconnecting Input Power” section on page 9-2.

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

Step 3 Remove the new network processing engine or network services engine from its static shielding bag.

Step 4 Using both hands, grasp the NPE or NSE by its metal carrier edges and orient it so that its printed circuit board components are upward. (See Figure 9-16.)

Caution Handle the network processing engine or network services engine by the carrier edges and handle only; never touch the printed circuit board components or connector pins.

Step 5 Align the left and right edges of the network processing engine or network services engine printed circuit board between the network processing engine slot guides.

Note For the NPE-175 and NPE-225, align the left and right edges of the network processing engine metal carrier into the guides.
