NFORMATION
The table or rack on which you mount the chassis
I
supports at least three times the weight of a fully
loaded chassis.
The recommended minimum space that is required
I
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
I
of the 8-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
I
8-slot chassis to ensure proper cooling in the
chassis.
There is at least 91.4 cm (36 in.) in back of the
I
chassis to:
Remove and replace power supplies in the
I
8-slot chassis.
Maintain proper cooling.
I
If the chassis is the first device in your rack, then
I
mount it about 10.2 cm (4 in.) up from the floor.
The power source is within approximately 2 meters
I
(6.6 feet) of the location where you plan to install
the Switch 4007R chassis.
Each of the power supplies connects to a
I
dedicated circuit. Do not connect the power
supplies to a power strip.
