1. Intel®Server Chassis SR1475 Feature Summary
The Intel®Server Chassis SR1475 is a 1U server chassis specifically designed to support the
Intel®Server Board SE7230NH1-E. The Intel®Server Chassis SR1475 is available as a
standalone chassis solution from Intel, and as an integrated system. The Intel®Server System
SR1475NH1-E consists of the Intel®Server Board SE7230NH1-E integrated into the Intel®
Server Chassis SR1475. The server board and the server chassis have feature sets designed to
support the high-density server market.
The Intel®Server Board SE7230NH1-E is available in two different configurations, the
SE7230NH1LC version and the SE7230NH1LX version. Only the SE7230NH1LX version is
available for integration into the Intel®Server Chassis SR1475, and all references to the Intel®
Server Board SE7230NH1-E in this document refers to the SE7230NH1LX version of the server
board. This document provides details on the server chassis feature set and technical
specifications. For technical details related to the Intel®Server Board SE7230NH1-E, please
refer to the Intel®Server Board SE7230NH1-E Technical Product Specification.

1.5 Hard Drive and Peripheral Bays
The server chassis is designed to support several different hard drive and peripheral
configurations. The hard drive bay is designed to support up to three fixed SATA or SCSI
drives, or three hot-swappable SATA or SCSI drives. SATA and SCSI hot-swap configurations
require an orderable accessory kit which includes the necessary cables, drive trays and
backplane. Reference the Intel®Server Chassis SR1400 Spares/Parts and Configuration List for
detailed accessory information.
The slim-line peripheral bay is capable of supporting any of the following slim-line devices: CD-
ROM drive, DVD Drive, DVD/CDR Drive, or floppy drive. If both a CD-ROM or DVD/CDR and
floppy drive are required, an optional kit is available to convert the first 1” hard drive bay to a
floppy drive bay. The kit includes the necessary cables and slim-line floppy drive mounting tray.

Revision 1.0 - 18 -
1.7 Power Sub-system
The power sub-system of the server chassis consists of a single non-redundant 350 W power
supply (PS) and provides several integrated management features including:
•Status LED
•Over-temperature protection circuitry
•Over-voltage protection circuitry
The power supply operates within the following voltage ranges and ratings: 100-127VAC (V) ∼
at 50/60 Hertz (Hz), 6 Ampere (A) maximum (max); 200-240VAC∼at 50/60 Hz, 3 A maximum.
1.8 System Cooling
The server chassis provides non-redundant system fans and dual non-redundant power supply
fans to provide sufficient air flow for fixed and hot-swap drive configurations, processors,
memory, and an add-in card, when external ambient temperatures remain within specified limits.
1.9 Chassis Security
The server chassis provides support for several system security features including a lockable
front bezel, chassis intrusion switch, and a Kensington* style lock attach point.
1.10 Rack and Cabinet Mounting Options
The server chassis was designed to support 19” wide by up to 24”-30” deep server cabinets.
The chassis can be configured to support either a relay rack / cabinet mount kit that can be
configured to support both 2-post racks and 4-post cabinets; or a tool-less sliding rail kit that is
used to mount the chassis into a standard (19” by up to 30” deep) EIA-310D compatible server
cabinet.
1.11 Front Bezels
The optional front bezel is made of molded plastic and uses a snap-on design. When installed,
its design allows for maximum airflow.

2. Cooling Sub-System
The cooling sub-system on the server chassis is compromised of four 40x40x56mm dual rotor
fans, one 40x40x28mm single rotor fan, two 40x40x28mm power supply fans, a CPU/memory
air duct, and a PS/electronics bay isolation air baffle, to provide the necessary cooling and
airflow to the system. A fan on the processor heat sink is not necessary in this chassis. In
order to maintain the necessary airflow within the system, the air baffle, CPU/memory air duct,
and the top cover need to be properly installed.
Note: The Intel®Server Chassis SR1475 does not support redundant cooling. Should a fan fail,
the system should be brought down as soon as possible to replace the failed fan.
