NFORMATION
The table 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 at least 7 cm (2.76 in.) on each side 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.
Remove and replace the fan trays in the 8-slot
chassis and 16-slot chassis.
Maintain proper cooling.
If the chassis is the first device in your rack, then
mount it about 10.2 cm (4 in.) up from the floor.
The power source is within approximately 2 meters
(6.6 feet) of the location where you plan to install
the CoreBuilder 9000 chassis.
