Server System SR2600UR/SR2625UR Service Guide 171
Main DC power disconnect: You are responsible for installing a properly rated DC power
disconnect for the server system. This mains disconnect must be readily accessible, and it
must be labeled as controlling power to the server. The circuit breaker of a centralized DC
power system may be used as a disconnect device when easily accessible and should be
rated no more than 10 amps.
Grounding the server: To avoid the potential for an electrical shock hazard, you must
reliably connect an earth grounding conductor to the server. The earth grounding
conductor must be a minimum 18AWG connected to the earth ground stud(s) on the rear
of the server. The safety ground conductor should be connected to the chassis stud with a
Listed closed two-hole crimp terminal having 5/8-inch pitch. The nuts on the chassis earth
ground studs should be installed with a 10 in/lbs torque. The safety ground conductor
provides proper grounding only for the server. You must provide additional, proper
grounding for the rack and other devices installed in it.
Overcurrent protection: Overcurrent protection circuit breakers must be provided as part
of each host equipment rack and must be incorporated in the field wiring between the DC
source and the server. The branch circuit protection shall be rated minimum 75Vdc, 10 A
maximum per feed pair. If the DC power system for the equipment rack is installed with
more than 10 amperes of protection, you must provide supplemental protection for
the server.
Power Cord Usage Guidelines
Warning: Do not attempt to modify or use an AC power cord set that is not the exact type required.
You must use a power cord set that meets the following criteria:
•
Rating: In the U.S. and Canada, cords must be UL (Underwriters Laboratories,
Inc.) Listed/CSA (Canadian Standards Organization) Certified type SJT, 18-3 AWG
(American Wire Gauge). Outside of the U.S. and Canada, cords must be flexible
harmonized (<HAR>) or VDE (Verband Deutscher Electrotechniker, German
Institute of Electrical Engineers) certified cord with 3 x 0.75 mm conductors rated
250 VAC (Volts Alternating Current).
•
Connector, wall outlet end: Cords must be terminated in grounding-type male plug
designed for use in your region. The connector must have certification marks
showing certification by an agency acceptable in your region and for U.S. must be
Listed and rated 125% of overall current rating of the server.
•
Connector, server end: The connectors that plug into the AC receptacle on the
server must be an approved IEC (International Electrotechnical Commission) 320,
sheet C13, type female connector.
•
Cord length and flexibility: Cords must be less than 4.5 meters (14.76 feet) long.
