Page 21: Module And Interface Card Capacity
Module and Interface Card Capacity Optional network modules and interface cards provide Cisco 3800 series routers with additional interfaces or functionality. Network Modules Network modules install directly into slots in the rear of the router. The Cisco 3845 router supports online insertion and removal (OIR, or hot swap) of network modules.
Page 22 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.
Page 23: Port Numbering
Port Numbering Each built-in network port on a Cisco 3800 series router, and each port or interface on a network module or interface card, is identified in Cisco IOS software by an interface type and a number or series of numbers separated by forward slashes (/).
