Installing the MX480 Chassis in the Rack Manually
To install the router in the rack (see Figure 64 on page 197 ):
CAUTION: If you are installing more than one router in a rack, install the
lowest one first. Installing a router in an upper position in a rack or cabinet
requires a lift.
CAUTION: Before front mounting the router in a rack, have a qualified
technician verify that the rack is strong enough to support the router's weight
and is adequately supported at the installation site.
CAUTION: Lifting the chassis and mounting it in a rack requires two people.
The empty chassis weighs approximately 65.5 lb (29.7 kg).
1.
Ensure that the rack is in its permanent location and is secured to the building. Ensure
that the installation site allows adequate clearance for both airflow and maintenance.
2.
Position the router in front of the rack or cabinet, centering it in front of the mounting
shelf. Use a pallet jack if one is available.
3.
With one person on each side, hold onto the bottom of the chassis and carefully lift
it onto the mounting shelf.
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.
4.
Slide the router onto the mounting shelf until the mounting brackets contact the rack
rails. The shelf ensures that the holes in the mounting brackets of the chassis align
with the holes in the rack rails.
5.
Install a mounting screw into each of the open mounting holes aligned with the rack,
starting from the bottom.
6.
Visually inspect the alignment of the router. If the router is installed properly in the
rack, all the mounting screws on one side of the rack should be aligned with the
mounting screws on the opposite side and the router should be level.
