Routers
This document describes how to install interface cards in Cisco 3800 series integrated services routers.

Installing Interface Cards
Interface cards install either into slots in the rear of the router, or into slots in network modules. Interface
cards come in the following types:
•
WAN interface card (WIC)
•
Voice interface card (VIC)
•
Voice/data T1/E1 WAN interface card (VWIC)
•
High-speed WAN interface card (HWIC)
Note
You can install any type of interface card—WIC, VIC, VWIC, or HWIC—into a router HWIC slot.
HWICs must be installed directly into router slots, not into network modules.
The Cisco 3825 router and the Cisco 3845 router each provide four interface card slots, labeled on the
rear panel by HWIC and a number. Each of these slots can be occupied by one single-wide WIC, VIC,
VWIC, or HWIC.
In addition, the HWIC 0 and HWIC 1 slots can be combined to hold one double-wide HWIC. The
HWIC 2 and HWIC 3 slots can also be combined to hold one double-wide HWIC.
Note
Although the HWIC 1 and HWIC 2 slots on the Cisco 3845 router are adjacent to each other, they cannot
be combined to hold a double-wide HWIC.
The maximum capacity of Cisco 3800 series routers for interface cards inserted directly into the chassis
is four WICs, VWICs, or HWICs, or two double-wide HWICs.
