If you install the chassis in a Metric rack slot, install the clip nuts
and screws in the closed slots of the rack-mount flanges. If you
install the chassis in Telco rack slots, position the chassis and then
install the screws and rack-mount clips in the open slots.
If you want to use the optional cable management device (Model
Number 3CB9EC7), attach it to the right preinstalled chassis
rack-mount flange. Install the chassis in the rack before you
install the cable management device.
If you want the chassis to protrude from the front of the rack,
install the alternate rack-mount flanges. See "Optional Alternate
Position Rack-mount Flanges" on page 18.
WARNING: To ensure mechanical stability and to avoid circuit
overloading and improper grounding, follow the rack manufacturer's
instructions for rack installation. If the instructions are unclear, consult a
qualified electrician.

Location Requirements

Install a CoreBuilder 9000 7-slot chassis in an area that meets the
following requirements:
Ambient (room) temperature is from 0 °C to 50 °C (32 °F to
122 °F).
Relative humidity is between 10 and 90 percent, noncondensing.
The table, shelf, or rack on which you mount the chassis supports at
least three times the weight of a fully loaded chassis.
The recommended minimum space that is required between the
front of the chassis and another vertical surface (such as a rack
door) is 8 cm (3 in.).
There is a sufficient amount of space on each side of the 7-slot
chassis to accommodate any cables along the side of the chassis.
There is a distance of 7 cm (2.76 in.) or greater on both sides of the
7-slot chassis to ensure proper cooling in the chassis.
There is at least 91.4 cm (36 in.) in back of the chassis to remove
and replace power supplies in the 7-slot chassis.
The power source is within approximately 2 meters (6.6 feet) of the
location where you plan to install the CoreBuilder 9000 system.
Each of the two power supplies connects to a dedicated circuit. Do
not connect the power supplies to a power strip.
