3.5.1
Connecting the Power Cord
Note:
When using a rack, wait to install the power cord(s) until after the server is in the rack.
3.5.2
Equipment Rack Precautions
Caution:
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 it on slide assemblies. The equipment rack must be installed
according to the manufacturer’s instructions. You must also consider the weight of any
other device installed in the rack.
Mains power disconnect —
The power cord(s) is considered the mains 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 a 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 power cords must be removed.
Grounding the rack installation —
To avoid the potential for an electrical shock
hazard, for AC power you must include a third wire safety ground conductor with the
rack installation. For DC power the two studs for chassis enclosure grounding must be
used for proper safety grounding. See “C” in
for the location of the ground
studs.
With AC power, if the server power cord is plugged into an 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 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.
AC overcurrent protection —
When AC power is used, the server is designed for a
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.
Caution:
Temperature —
The operating temperature of the server, when installed in an
equipment rack, must not go below 5°C (41°F) or rise above 35°C (95°F). Extreme
fluctuations in temperature can cause a variety of problems in your server.
