Chapter 9 Removing and Installing the NPE or NSE
Removing and Replacing the NPE or NSE
Caution Do not align the network processing engine or network services engine metal carrier between the slot
guides (for all except the NPE-175 and NPE-225). Doing so damages components on the network
processing engine’s printed circuit board as you slide the network processing engine into its chassis slot.
Note The NPE-300 and NPE-400 are compatible only with the Cisco 7200 VXR router and
Cisco
uBR7246VXR router; the NPE-300 and NPE-400 are keyed to prevent insertion in the Cisco 7200
series routers (7202, 7204, and 7206) and Cisco
uBR7200 series routers (Cisco uBR7223 and Cisco
uBR7246).
Note The NSE-1 is compatible with the Cisco 7200 VXR routers only. It is keyed to prevent insertion in the
Cisco 7200 series routers and the Cisco uBR7200 series routers.
