Intel® Server System SR2612UR TPS
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.
10.4 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.
