Intel® SR870BN4 Server System Product Guide 13
Part I: User’s Guide
1 System Description
2 Board Set Description
3 Configuration Software and Utilities
4 Hot-swapping System Components
This manual consists of two parts:
User’s Guide, beginning on page 13describes procedures that DO NOT REQUIRE internal
server access. The user does not need to be a qualified service technician to perform
procedures listed in the User’s Guide.
Service Technician’s Guide, beginning on page 175describes procedures that REQUIRE
internal server access. The user must be a qualified service configuration technician to perform
procedures listed in the Service Technician’s Guide.
WARNING
Only a QUALIFIED SERVICE TECHNICIAN is authorized to remove
the server’s covers and to access any of the components inside the server,
except as noted herein. Before removing top covers or modules, see
“Figure 58. Locating System Modules” on page 181 and “Warnings and
Cautions” on page 179.
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. The anchors must be
able to withstand a force of up to 113 kg (250 lbs.). The user 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.
Main AC power disconnects: The user is 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 unit, not just to the server(s).
Grounding the rack installation: To avoid the potential for an electrical
shock hazard, the user must include a third wire safety-grounding
conductor with the rack installation. If the server power cord is plugged
into an AC outlet that is part of the rack, then the user must provide
proper grounding for the rack itself. If the server power cord is plugged
into a wall AC outlet, the safety-grounding conductor in the power cord
provides proper grounding only for the server. The user must provide
additional, proper grounding for the rack and other devices installed in it.

14 Intel® SR870BN4 Server System Product Guide
Overcurrent protection: The server is designed for an AC line voltage
source with up to 20 amperes of overcurrent protection. If the power
system for the equipment rack is installed on a branch circuit with more
than 20 amperes of protection, the user must provide supplemental
protection for the server.
WARNING – POWER CORD RATING
Do not attempt to modify or use an AC power cord that is not the exact
type required. The user must use a power cord that meets the following
criteria:
•Rating: For U.S./Canada cords must be UL Listed/CSA Certified, 16/3,
75C type, VW-1, SJT/SVT, with NEMA 5-15P or NEMA 6-15P
attachment plug and IEC 320 C13 input power connector rated 15 amps.
For outside U.S./Canada cords must be flexible harmonized (<HAR>)
rated 250 V, 1.0 mm minimum conductor size with IEC 320 C13 input
power connector and rated for no less than 10 amps.
•AC Attachment Connector, wall outlet end for outside U.S./Canada:
The AC wall attachment plug should be a three conductor grounding
type, rated at 125 V, 15 amps and must be for the configuration of the
specific region or country. The AC wall attachment plug must bear at
least an accepted safety agency certification mark for the specific region
or country.
•Input Power Connector, server end: The connectors that plug into the
AC receptacles on the server must be an IEC 320, sheet C13, type
female connector and are rated for 125 V/250 V, 15 A.
•Cord length and flexibility: Cords must be less than 4.5 meters (14.76
feet) long.
CAUTION
Temperature: The range of temperatures in which the server operates when
installed in an equipment rack, must not go below 10 °C (50 °F) or rise above
35 °C (95 °F). Extreme fluctuations in temperature can cause a variety of
problems in your server.
Ventilation: The equipment rack must provide sufficient airflow to the front
of the server to maintain proper cooling. The rack must also include
ventilation sufficient to exhaust a maximum of 1500 W (5,100 BTU/hr) for
the server. The rack selected and the ventilation provided must be suitable to
the environment in which the server will be used.
