Installing Slot Dividers in Network Module Slots
Installing Slot Dividers in Network Module Slots
In a Cisco 2851 router, you can install a slot divider in the network module slot to reduce the slot width
from extended double-wide to extended single-wide. Use of a slot divider alone (without a filler panel)
creates a slot width suitable for an enhanced extended single-wide (NME-X) network module. Use of a
slot divider with a filler panel creates a slot width suitable for an enhanced single-wide (NME) or older
version (NM) single-wide network module.
Figure 1 shows a slot divider with captive screw for the network module slot in Cisco 2851 routers.
Figure 1 Slot Divider for Network Module Slots
Install slot dividers into network module slots as follows:
Step 1 Insert the top rails of the slot divider between the two guide rails in the top of the network module slot.
See Figure 2.

Step 2
Push the slot divider in until it is fully seated.
Step 3 Tighten the retention screw on the front of the slot divider with a number 1 Phillips screwdriver. See
Figure 3. When the slot divider is fully inserted, its front surface is flush with the panel of the router. See
Figure 4.
