Installing the Chassis
The Cisco Remote PHY Shelf 7200 can be either mounted on the rack at the front or in the middle. Also, the
router can be either mounted on a standard 19-inch wide four-post equipment rack unit or a two-post rack
unit.
Note
The Cisco Remote PHY Shelf 7200 fully configured system can weigh up to 271 lbs, components must be
removed from the chassis to make the chassis lighter for rack installation. Remove all front power modules
and front RPD cards for rack mounting to reduce the weight. The PIC cards and Fan Tray can remain in the
system during rack mounting. For instructions on how to remove the components, see the monitoring sections.
Make sure that you place the cards and modules in an anti-static bag until you install the chassis in the rack.
Proceed with the installation if you have already unpacked your chassis and read all the site requirements for
your new equipment.
Required Tools and Equipment
• ESD-preventive wrist strap
• #2 Phillips torque screwdriver
• Flat-head screwdriver
Verifying Rack Dimensions
Before you install the chassis, measure the space between the vertical mounting flanges (rails) on your
equipment rack to verify that the rack conforms to the measurements shown in the following figure.
