The Cisco 1721, 1760, 2621XM, 2651XM, 2691, 3725, 3745, and 7206 VXR NPE-400 Routers
When a network module is inserted, it fits into an adapter called the network module expansion bus. The
expansion bus interacts with the PCI bridge in the same way that the fixed LAN ports do; therefore, no
critical security parameters pass through the network module (just as they don't pass through the LAN
ports). Network modules do not perform any cryptographic functions.
WICs are similar to network modules in that they greatly increase the router's flexibility. A WIC is
inserted into one of two slots, which are located above the fixed LAN ports. WICs interface directly with
the processor. They do not interface with the cryptographic card; therefore no security parameters will
pass through them. WICs cannot perform cryptographic functions; they only serve as a data input and
data output physical interface.
The physical interfaces include a power plug for the power supply and a power switch. The router has
two Fast Ethernet (10/100 RJ-45) connectors for data transfers in and out. The module also has two other
RJ-45 connectors on the back panel for a console terminal for local system access and an auxiliary port
for remote system access or dial backup using a modem. The 10/100Base-T LAN ports have
Link/Activity, 10/100Mbps, and half/full duplex LEDs.
