Installing the M40e Chassis into the Rack

Before installing the chassis:

• Verify that the router site meets the requirements described in M40e Site Preparation Checklist.
• Place the rack in its permanent location, allowing adequate clearance for airflow and maintenance, and secure it to the building structure. For details, see M40e Rack Size and Strength.
• Read the information in M40e Chassis Lifting Guidelines.
• Remove the router from the shipping carton, as described in Unpacking the M40e Router.

After you have removed components as described in Removing Components from the Chassis Before Installing the M40e Router Without a Lift, the chassis is light enough for a team of installers to lift into the rack.

Caution: The reduced weight of the chassis is approximately 115 lb (52 kg). Installing it into the rack still requires three people to lift and an additional person to secure the mounting screws.

If you are installing multiple routers in a rack, install the lowest one first and proceed upward (see Figure 2):

1. If you are front-mounting the router, remove the center-mounting brackets from each side of the chassis. (Also, we recommend installing a shelf or other support for the rear of the chassis.)
2. Attach the lifting handle to the rear of the chassis, screwing the thumbscrews at its corners into the holes located next to the SFM slots on the chassis (see Figure 1). If you are installing the chassis in a lower rack space, use the set of holes adjacent to the slots labeled SFM 0 and SFM 1. If you are installing the chassis in an upper rack space, use the set of holes adjacent to the slot covers labeled Do not install an SFM in this slot.

3. Prepare to lift the router:
   • One person stands behind the chassis and grasps the lifting handle.
   • Two people stand on either side of the chassis. Each grasps the bar at the bottom of the FPC card cage with one hand and places the other hand under the chassis near the rear.
4. Lift the chassis and position it in the rack.

   Warning: To prevent injury, keep your back straight and lift with your legs, not your back. Avoid twisting your body as you lift. Balance the load evenly and be sure that your footing is solid.

5. Align the bottom hole in both front support posts or center-mounting brackets with a hole in each rack rail, making sure the chassis is level.
6. Install one of the mounting screws provided into each of the two aligned holes. Use a 5/32-in. Allen wrench to tighten the screws.
7. Moving up each post or bracket, 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. Loosen the thumbscrews on the lifting handle and remove it from the chassis.
10. Proceed to the instructions in Reinstalling the M40e Components into the Chassis.
