Install the Router Using a Mechanical Lift

Using a mechanical lift to maneuver the router into the rack is recommended because of the router's size and weight. The lift must be able to accommodate the router's weight—approximately 280 lb (127 kg) fully configured—and must fit between the support posts of the rack.  

If you are installing two routers in one rack, install the lower one first.

First, perform the following prerequisite procedures:

• Place the rack in its permanent location, allowing adequate clearance for airflow and maintenance, and secure it to the building structure. For details, see Rack Requirements.
• Read the information in Installation Safety Guidelines and Warnings, with particular attention to Chassis Lifting Guidelines.
• Remove the router from the shipping crate, as described in Prepare to Install the Router.

Then, perform the following procedures to install the router:

1. If you are installing the router in the upper half of the rack, install the C-bracket first (see Rack-Mounting Brackets). Follow this procedure:

1. Select the height in the rack at which to mount the C-bracket. The M40 router is 35 in. (89 cm or 20 U) high, so if you are mounting two routers in the rack leave at least that much distance between the C-bracket shelf and both the top and bottom cross-pieces of the rack.
2. As you stand in front of the rack, position the C-bracket so that the shelf is protruding toward you, and align the C-bracket mounting holes with holes in the rack rails. If you are front mounting the router, install the C-bracket into the rack from the rear. Make sure the mounting holes on both sides are parallel.
3. Insert and tighten the provided screws.

2. If you are center-mounting the router, attach a center-mounting ear to either side of the chassis. For information about the center-mounting ears, see Rack-Mounting Brackets.
3. Load the router onto the lift, making sure it rests securely on the lift platform.
4. Use the lift to position the router at the correct height in the rack.
5. Align the bottom hole in both front- or center-mounting ears with a hole in each rack rail, making sure the chassis is level.
6. Install one of the mounting screws provided (in the accessory box shipped with the router) into each of the two aligned holes.
7. Moving up each post or ear, install a screw in every mounting hole.
8. Verify that all the mounting screws on one side of the rack are aligned with the mounting screws on the opposite side and that the router is level.
9. Move the lift away from the rack.
10. To complete the installation, proceed to Connect the Router to Management and Alarm Devices.
