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.
