13.4 Power Cord Usage Guidelines - Intel SR1625UR Technical Product Specification

Intel® Server System SR1625UR TPS
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.
If DC power supplies are installed:
Connection with a DC (Direct Current) source should only be performed by trained service
personnel. The server with DC input is to be installed in a Restricted Access Location in
accordance with articles 110-16, 110-17, and 110-18 of the National Electric Code, ANSI/NFPA
70. The DC source must be electrically isolated by double or reinforced insulation from any
hazardous AC source.
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.

13.4 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
Revision 1.5
