WARNING
Anchor the equipment rack: The equipment rack must be anchored to an
unmovable support to prevent it from falling over when one or more
servers 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:
Main AC power disconnect: The AC power cord(s) is considered the main
disconnect for the server 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 server(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 server 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 server power cord is plugged into a wall AC outlet, the
safety ground conductor in the power cord provides proper grounding only
for the server. You must provide additional, proper grounding for the
rack and other devices installed in it.
Overcurrent protection: The server is designed for an AC line voltage
source with up to 20 amperes of overcurrent protection per cord feed. If
the power system for the equipment rack is installed on a branch circuit
with more than 20 amperes of protection, you must provide supplemental
protection for the server. The overall current rating of a server configured
with two power supplies is less than 4 amperes.
