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 installe rs to lift into the rack.
CAUTION: The reduced weight of the chassis is approximately 115 lb (52 kg).
Installing it intothe rack still requires three people tolift 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 intothe holes located next to the SFM slots on the chassis (see
Figure 43). If you are installing the chassisin a lower rack space, use the set
of holes adjacent to the slots labeled SFM 0 and SFM 1. If you are installing
