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. The Cisco 3825 router does not support OIR.

Caution The Cisco 3845 router supports OIR with similar modules only. If you remove a network module, along with any installed WAN or voice interface cards, install another module and card combination exactly like it.

Caution The Cisco 3825 router does not support OIR of network modules. To avoid damaging the module, you must turn off electrical power and disconnect network cables before you insert the module into a router slot.

The Cisco 3825 router provides two slots for network modules. The lower network module slot of this router, labeled 1 on the rear panel, can hold either of the following sizes of network modules:

•One single-wide network module

•One extended single-wide network module

The upper network module slot of the Cisco 3825 router, labeled 2 on the rear panel, can hold any of the following sizes of network modules:

•One single-wide network module

•One extended single-wide network module

•One double-wide network module

•One extended double-wide network module

The Cisco 3845 router provides four slots for network modules, labeled 1, 2, 3, and 4 on the rear panel. Each slot can hold either of the following sizes of network modules:

•One single-wide network module

•One extended single-wide network module

Slots 1 and 2 can also be combined to hold either of the following sizes of network modules:

•One double-wide network module

•One extended double-wide network module

Slots 3 and 4 can be combined in the same way to hold one double-wide or extended double-wide network module.
