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.
