Module and Interface Card Capacity

Note The terms single-wide,extended single-wide,double-wide, and extended double-wide refer to the physical size of a network module. Enhanced network modules offer additional functionality; this functionality is not directly related to the module’s size.

Note The Cisco 3825 router supports one high-density analog-digital extension module for voice and fax. The Cisco 3845 module supports two of these modules.

Certain network module configurations require the installation or removal of a slot divider in the module slot. All configurations require blank faceplates or slot adapters to be installed over unused slots for cooling, electromagnetic interference (EMI) reduction, and safety. Procedures for installing network modules, slot dividers, slot adapters, and blank faceplates are described in “Installing Network Modules in Cisco 3800 Series Routers” and the Cisco Network Modules Hardware Installation Guide.

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 insert any kind 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 slot 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, VICs, VWICs, or HWICs, or two double-wide HWICs.

Caution Cisco 3800 series routers do not support OIR (hot swap) of interface cards inserted directly into router slots. You must turn off the router before installing or removing an interface card.
