EQUIREMENTS
Each of the power supplies connects to a
dedicated circuit. Do not connect the power
supplies to a power strip.
The surface on which you want to locate the
CoreBuilder 9000 chassis is level.
Have the required cables available at your site to
make physical connections in your Switch
configuration.
Precautionary Guidelines
Ambient temperature for the CoreBuilder 9000
Switch must not exceed 50 C (122 F).
Safety regulations stipulate that for a:
7-slot chassis, the table, shelf, or rack on which
the Switch rests can support at least 115.65 kg
(255 lb), which is three times the weight of a
fully loaded 7-slot chassis.
8-slot chassis, the table, shelf, or rack on which
the Switch rests can support at least 215 kg
(474 lb), which is three times the weight of a
fully loaded 8-slot chassis.
16-slot chassis, the table, shelf, or rack on
which the Switch rests can support at least
265.5 kg (585 lb), which is three times the
weight of a fully loaded 16-slot chassis.
For rack installations, the selected rack is grounded
in accordance with the rack manufacturer's
recommendations.

AFETY
AND
REINSTALLATION
NFORMATION
To reduce the possibility of personal injury or
serious damage to the chassis, use at least two
people to install the chassis. This is especially
important for rack installations, because you must
hold the chassis in place while you secure the
chassis to the rack.
Bolt the rack to the floor.
Make certain that the rack is properly aligned and
squared. Use a framing tool to ensure that the rack
is squared.
Brace the top of the rack against the wall.
Provide sufficient space in front of and behind the
chassis so that you can service it easily and provide
proper ventilation.
Provide at least 7 cm (2.76 in.) on each side of
the 7-slot chassis to ensure proper cooling in
the chassis.
Provide at least 91.4 cm (36 in.) in back of the
Switch to remove and replace power supplies in
the 7-slot chassis, and to remove and replace
fan trays in the 8-slot chassis and 16-slot
chassis.
Provide sufficient space on the sides of a 7-slot
chassis and at the top or bottom of the 8-slot
chassis and the 16-slot chassis to allow for bend
radius for cables when using a cable
management device.
