Modifying the Width of Network Module Slots Figure 30 Slot Divider for Double-Wide Network Module Slots (Generic Router) 121387 All network module slots must be covered by network module faceplates, blank faceplates, or slot adapters for cooling, electromagnetic interference (EMI) reduction, and safety. The network module hardware kit for Cisco 3800 series routers contains four blank faceplates. Each blank faceplate covers one standard single-wide network module slot. 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 Modifying the Width of Network Module Slots T o reduce extended single-wide and extended double-wide network module slots in width to hold smaller network modules, or to cover unused slots, you may need a combination of blank faceplates, slot dividers, and slot adapters. To reduce a slot in width: • To reduce an extended single-wide slot to standard single-wide, install one slot adapter on the right. See Figure 31. • To reduce an extended double-wide slot to standard double-wide, install two slot adapters on the right. See Figure 32.
