This section provides a list of parts and tools you need to remove and replace the network processing engine (NPE) or network services engine (NSE) in Cisco 7200 series routers and Cisco uBR7200 series routers. This section also includes safety and ESD-prevention guidelines to help you avoid injury to yourself and damage to the equipment. See the "Obtaining Documentation" section for ordering and contact information. The following sections are found in this chapter:
You need the following parts and tools to remove and replace an NPE or NSE in Cisco 7200 series or Cisco uBR7200 series routers:
If your router is mounted in a 4-post or telco-type rack, make sure you have at least one other person available to assist you with removing the chassis from the rack.
The network processing engine and network services engine have different requirements for both hardware and software. See the "NPE or NSE Requirements" section.
When installing an NPE-175, NPE-225, NPE-300, 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.
 |
Note Instructions for upgrading the boot helper image on the I/O controller are contained in the Memory Replacement Instructions for the Network Processing Engine or Network Services Engine and Input/Output Controller publication, which accompanied your new network processing engine or network services engine. |
|
Note The Cisco 7200 VXR routers support all versions of the NPE and the NSE-1. The Cisco 7200 routers support the NPE-100, NPE-150, NPE-175, NPE-200, and NPE-225. The Cisco 7206 as a router shelf in a Cisco AS5800 Universal Access Server supports the NPE-200 only. The Cisco 7206VXR as a router shelf supports the NPE-200 and NPE-300 only. The Cisco uBR7200 series supports only the NPE-150 and NPE-200. The Cisco uBR7246 VXR router supports only the NPE-300. |
|
Note The NPE-300 is compatible with the Cisco 7200 VXR and Cisco uBR7246 VXR routers only. The NPE-300 is keyed to prevent insertion in the Cisco 7200 series routers (7202, 7204, and 7206) and the Cisco uBR7246 and Cisco uBR7223 universal broadband routers. |
|
Note The NSE-1 is compatible with the Cisco 7200 VXR series routers only, and is keyed to prevent insertion in the Cisco 7200 series routers (7202, 7204, and 7206) and the Cisco uBR7246 and Cisco uBR7223 universal broadband routers. |
Table 5-1 and Table 5-2 list the recommended minimum Cisco IOS software release to ensure proper operation of the network processing engine or network services engine in supported router platforms.

Follow these basic guidelines when working with any electrical equipment:
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.
The network processing engine or network services engine, I/O controller, port adapters, and Cisco uBR7200 series cable modem cards consist of printed circuit boards that are fixed in a metal carrier. Electromagnetic interference (EMI) shielding, connectors, and a handle are integral components of the carrier. Handle the network processing engine or network services engine, I/O controller, port adapters, and Cisco uBR7200 series cable modem cards by their carrier edges and handles; never touch the printed circuit board or connector pins.
Figure 5-2 shows the location of a printed circuit board in a network processing engine or network services engine, I/O controller, or Cisco uBR7200 series cable modem card metal carrier. Do not touch the printed circuit board when handling any of the components.
Figure 5-3 shows the location of a printed circuit board in a port adapter metal carrier. Do not touch the printed circuit board when handling a port adapter.
Although the metal carrier helps to protect the printed circuit boards from ESD, wear a preventive antistatic strap whenever handling the network processing engine or network services engine, I/O controller, port adapters, or Cisco uBR7200 series cable modem cards. Ensure that the strap makes good skin contact and connect the strap's clip to an unpainted chassis surface to channel unwanted ESD voltages safely to ground.
If no wrist strap is available, ground yourself by touching the metal part of the chassis.
 |
Caution Make sure to tighten the captive installation screws on the network processing engine or network services engine, Cisco uBR7200 series cable modem cards, and the I/O controller (use a number 2 Phillips or a 3/16-inch flat-blade screwdriver). These screws prevent accidental removal, provide proper grounding for the router, and help to ensure that the network processing engine or network services engine, Cisco uBR7200 series cable modem cards, and the I/O controller are properly seated in the router midplane. |
Following are guidelines for preventing ESD damage:
|
Caution Periodically check the resistance value of the antistatic strap. The measurement should be within the range of 1 and 10 megohms. |
