Installing the Chassis into the Rack

After you have removed components as described in Removing Components from the Chassis on page 84, 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.

Perform the following procedures (see Figure 44):

1.If you are front-mounting the router, remove the center-mounting ear 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 43). 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
