The mounting holes are bidirectional. You can hang the router with the front bezel facing upward or
downward.
Keep at least 1 inch (2.5 cm) of clear space beside the cooling inlet and exhaust vents.
Tip When choosing a location for wall-mounting the router, consider cable limitations and wall structure.
To mount the router on a wall, follow these steps:
Step 1 Determine the required distance between mounting holes on the router. Figure 2-41 shows the
wall-mount holes located on the underside of the router.
Note For most router models, the distance between mounting holes is 8.2 inches (208 mm), as shown
in Figure 2-41. For the Cisco 866 and Cisco 867 models, the distance is 7.85 inches (199 mm).
Verify the required distance before drilling the holes.

Step 2
Insert the screws, with anchors, into the wall. Leave 1/8 inch (0.32 cm) between the screw head and the
wall. See Figure 2-42.
