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.
2.
Insert a flat-blade screwdriver into the gap around the craft interface and
gently pry the impeller assembly forward until you can grasp the sides of the
assembly and slide it halfway out of the chassis.
Place one hand under the assembly to support it, slide it completely out of the
chassis, and place it on the antistatic mat or in the electrostatic bag.
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.)
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
