Installing Network Modules in Cisco 3800 Series Routers

Figure 30 Slot Divider for Double-Wide Network Module Slots (Generic Router)
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.

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.
