The Cisco 7200 series and Cisco uBR7200 series memory systems are part of the network processing

engine or network services engine. The network processing engine is available in nine versions: the

NPE-100, NPE-150, NPE-175, NPE-200, NPE-225, NPE-300, NPE-400, NPE-G1 and NPE-G2. The

network services engine is available in one version, the NSE-1.

The NPE-100, NPE-150, NPE-175, NPE-200, and NPE-300 have reached their end-of-life and are no

longer sold, although they are still supported in existing installations. For information about each pro-

cessor’s end-of-life cycle, see the Cisco 7200 Series Routers Bulletins at the following URL:

http://www.cisco.com/en/US/products/hw/routers/ps341/prod_bulletins_list.html.

Note The Cisco uBR7246VXR universal broadband router does not support the NPE-G1 processor but must

use the UBR7200-NPE-G1 processor, which contains the bootflash code required to boot the router.

Unless otherwise indicated, all references to NPE-G1 in this document also refer to the

UBR7200-NPE-G1 processor.

Table 2-1 shows the current network processing engine or network services engine options and

restrictions for Cisco 7200 series and Cisco uBR7200 series routers. Table 2-2 shows the network

processing engine options for Cisco 7200 series and Cisco uBR7200 series routers that have reached

their end-of-life and are no longer sold, but are still supported in existing installations.
