Installing the 6400-S
Physical Installation 1
Anchor the equipment rack that will contain the 6400.
The equipment rack must be anchored to an unmovable support to prevent it
from falling over when one or more systems are extended in front of the rack
on slides. You must also consider the weight of any other device installed in
the rack. A crush hazard exists should the rack tilt forward which could cause
serious injury.
If AC power supplies are installed
Mains AC power disconnect
The AC power cord(s) is considered the mains disconnect for the 6400-S and
must be readily accessible when installed. If the individual server power
cord(s) will not be readily accessible for disconnection then you are
responsible for installing an AC power disconnect for the entire rack unit. This
main disconnect must be readily accessible, and it must be labeled as
controlling power to the entire rack, not just to the 6400-S(s). To remove all
power, two AC cords must be removed.
Grounding the rack installation
To avoid the potential for an electrical shock hazard, you must include a third
wire safety ground conductor with the rack installation. If the 6400-S power
cord is plugged into an AC outlet that is part of the rack, then you must
provide proper grounding for the rack itself. If the 6400-S power cord is
plugged into a wall AC outlet, the safety ground conductor in the power cord
provides proper grounding only for the 6400-S. You must provide additional,
proper grounding for the rack and other devices installed in it.
