Installing Network Modules in Cisco 3800 Series Routers This document describes how to install network modules in Cisco 3800 series routers. It contains the following sections: • Installing Network Modules, page 51 • Modifying the Width of Network Module Slots, page 53 • Installing and Removing Slot Dividers, page 55 • Installing and Removing Slot Adapters, page 59 • Installing Blank Faceplates, page 60 Installing 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 OL-5973-01 Installing Network Modules in Cisco 3800 Series Routers 51
