Install the Chassis into the Rack

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 57 lb (25.8 kg) and about 61 lb (27.6 kg) for the M5 router or 67 lb (29.5 kg) for the M10 router depending on configuration—and must fit between the support posts of the rack.

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 Prepare 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 Unpack the Router.

Then, perform the following procedures to install the router:

1. If you are front-mounting the router, move the mounting ears on the chassis from the center-mounting position to the front-mounting position, and install the support shelf. For instructions, see Choose Front or Center Mounting.
2. Position the chassis at the appropriate height in the rack:
   • If using a mechanical lift, load the router onto the lift, making sure it rests securely on the lift platform. Use the lift to raise the chassis to the correct height.
   • If not using a mechanical lift, have one person stand behind the router and another person in front. Grasp the chassis, lift it, and position it at the correct height. Have a third person ready to install the mounting screws.
3. Align the bottom hole in both mounting ears with a hole in each rack rail, making sure the chassis is level.
4. 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.
5. Install a mounting screw into the top hole in each mounting ear.
6. Verify that the router is level.
7. If using a mechanical lift, move it away from the rack.
8. To continue the installation, proceed to Connect the Router and Perform Initial Configuration.
