Install the two rack-mount guides on the chassis:

  1. Position a rack-mount guides on the side of the chassis with its two holes aligned to the two screw holes on the side of the chassis, and use two M4 flat-head screws to attach the guides to the chassis. Tighten the screws to a torque of 13.27 in-lb (1.5 N-m).

  2. Repeat with the other rack-mount guides on the other side of the router.

Step 3

Install the guide rails to the rack:

  1. Position the guide rails at the desired levels on the back side of the rack and use four 12-24 screws or four 10-32 screws, depending on the rack thread type, to attach the rails to the rack.

    Note

     
    For racks with square holes, you may need to position a 12-24 or 10-32 cage nut behind each mounting hole in a guide rail before using a 12-24 or 10-32 screw.

  2. Repeat with the other guide rail on the other side of the rack.

  3. Use a tape measure and level to verify that the rails are at the same height and horizontal.

Step 4

Insert the router into the rack and attach:

  1. Holding the router with both hands, position the back of the router between the front posts of the rack.

  2. Align the two rack-mount guides on either side of the router with the guide rails installed in the rack. Slide the rack-mount guides onto the guide rails, and then gently slide the router all the way into the rack.

    Note

     
    If the router does not slide easily, try realigning the rack-mount guides on the guide rails.

  3. Holding the chassis level, insert two screws (12-24 or 10-32, depending on the rack type) through the holes in each of the rack-mount brackets and into the cage nuts or threaded holes in the rack-mounting rail.

  4. Tighten the 10-32 screws to 20 in-lb (2.26 N.m) or tighten the 12-24 screws to 30 in-lb (3.39 N.m).

Connect AC Power to the Chassis


Caution
The chassis relies on the protective devices in the building installation to protect against short circuit, overcurrent, and ground faults. Ensure that the protective devices comply with local and national electrical codes.

Note
We recommend that you occupy both the power supply slots of the fixed port routers with power supplies. In case a power module fails, it is recommended to retain the failed power module in its slot until it is replaced with a new power module. This recommendation ensures that the system airflow is not impacted adversely, which may then result in the overheating of the router and its components.

Procedure

Step 1

Verify that the AC cable is installed in the correct AC source and outlet type.

Step 2

Attach the AC power cable to the AC input of the AC Power module.

Step 3

Place the cable through the opening in the cable clamp.

Step 4

Slide the cable clamp toward the plug.

Step 5

Close the cable clamp on the shoulder of the power cable to secure the power cable.
