Installing the Chassis 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—between 80 lb (36 kg) and about 134 lb (61 kg) depending on configuration—and must fit between the support posts of the rack.

Note: If you are installing multiple routers in one rack, install the lowest one first and proceed upward in the rack.

First, perform the following prerequisite procedures:

• Verify that the router site meets the requirements described in Preparing for Router Installation.
• 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 carton, as described in Unpacking the Router.

Then, perform the following procedures to install the router:

1. If you are front-mounting the router, replace the center-mounting hardware on the chassis with front-mounting hardware as described in Choosing Front-Mounting or Center-Mounting.
2. Load the router onto the lift, making sure it rests securely on the lift platform.
3. Use the lift to position the router at the correct height in the rack.
4. Align the bottom hole in both front-mounting or center-mounting brackets with a hole in each rack rail, making sure the chassis is level.
5. Install one of the mounting screws provided (in the accessory box shipped with the router) into each of the two aligned holes. Use a Phillips screwdriver to tighten the screws.
6. Moving up each bracket, install three more screws in each front-mounting bracket or center-mounting bracket. The recommended installation pattern places the second screw a distance of 2 U (3.5 in. or 8.9 cm) above the first, the third screw 3 U (5.25 in. or 13.34 cm) above the second, and the fourth screw in the topmost hole in the bracket (2 U above the third screw).
7. 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.
8. Move the lift away from the rack.
9. To continue the installation, proceed to Connecting the Router .
