Installing and Removing Slot Dividers Caution Cisco 3800 series routers do not support online insertion and removal (OIR, or hot swap) of interface cards inserted directly into router slots. You must turn off the router before installing or removing an interface card. The Cisco Interface Cards Installation Guide describes how to install interface cards in router slots and network modules. The Cisco 3800 Series Routers Cards and Modules document links to resources for understanding, installing, and configuring cards and modules for Cisco 3800 series routers. Empty slots must be covered with blank faceplates for cooling, electromagnetic interference (EMI) reduction, and safety. Procedures for installing slot dividers and blank faceplates are described in the following sections. Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place. Statement 1029 Installing and Removing Slot Dividers You can remove a slot divider to combine two single-wide HWIC slots into a double-wide slot, or install a slot divider to convert a double-wide slot into two single-wide slots. Installing Slot Dividers in HWIC Slots Cisco 3800 series routers use two different type of HWIC slot dividers: • The Cisco 3825 router uses a two-pronged metal slot divider. See Figure 37. • The Cisco 3845 router uses a slot divider with a plastic body and a screw tab. See Figure 38.
