Installing the Router
Step 11 Using the wrench, screw the M8 x12 screws (with M8 spring washer) into the two support bolt holes on either

Step 12 Screw a M8 x12 bolt (with M8 spring washers) into the second bolt hole on either side of the router (see the
above figure).
Step 13 Ensure that the front of the router is vertical, and tighten the four screws to 13 to 15 ft lbs (17.6 to 20.3 Nm).
Step 14 (Optional) When using the optional Cisco external omnidirectional antenna, connect it to the router.
Hand-tighten the antenna to the router.
Note

When the antenna is not installed on the router, it is mandatory to install the antenna dust cap that is
shipped with the router. This dust cap protects the router interior from environmental elements like
water, heat, cold, and dust.
