Fast Ethernet HWICs Supported Platforms
Install the Fast Ethernet HWICs in the following Cisco routers:
•Cisco 1841 integrated services router
•Cisco 2800 series integrated services routers
•Cisco 3800 series integrated services routers
Note Insert Fast Ethernet HWICs into HWIC slots only. They do not fit into WIC/VIC slots.
Table 1 shows the maxmum number of each type of HWIC that may be installed, the slot locations, and slot numbering for each platform.
For information about HWIC slot locations on each router, see the “Interface Card Slot Locations and Numbering on Cisco Access Routers” section of the Cisco Interface Cards for Cisco Access Routers guide located at:

Fast Ethernet HWICs Port Numbering
Port numbers identify the interfaces on the modules and interface cards installed in the router. Modules and interface cards are identified by three digits: slot number/subslot number/port number.
For example, HWIC port 0 in HWIC subslot 1 of router slot 0 is represented as:
interface FastEthernet 0/1/0
2
