1. Overview
The SR2300 is a 2U server chassis that is designed to support the Intel® Server Boards
SE7500WV2 and SE7501WV2. Both the boards and the chassis have a feature set that is
designed to support the high-density server market. This chapter provides a high-level overview
of the chassis features. Greater detail is provided in the following chapters.

The I/O connector locations on the back of the chassis are pre-cut, so the use of an ATX style
I/O shield is not required. The supplied EMI gasket must be installed to maintain
Electromagnetic Interference (EMI) compliance levels.
Note: The figure above is shown with a 500W power supply and the optional redundant 500W
power supply spare.

1.6 Power Supply
The SR2300 supports two power supply models: An EPS2U 480W non-redundant power
supply and the TPS 500W supply supporting redundant 1+1 configurations with TPS500W
modules. The power subsystem supports the implementation of remote management features,
including remote enable that permits power to be activated from a variety of sources.
The TPS 500W supply consists of the power supply bay and one power supply module. A
second power supply module can be purchased to provide a redundant, 1+1 system. The
supply operates within the following voltage ranges and is rated as follows:
• 90 - 132VAC∼at 50/60 Hertz (Hz); 7.0A maximum
• 180 - 264VAC∼at 50/60 Hz; 3.5A maximum

SR2300 2U Server Chassis Technical Product Specification Overview
Revision 1.2
Intel Order Number A94546-004

The EPS1U 480W supply consists of a single integrated power supply unit. It operates within
the following voltage ranges and is rated as follows:
• 90 - 132VAC ∼at 50/60 Hertz (Hz); 8.4A maximum
• 180 - 264VAC ∼at 50/60 Hz; 4.2A maximum
With either power supply configuration, the power supply provides 480 watts of power and is
designed to minimize EMI.
1.7 System Cooling
The chassis includes three 60-mm non-hot-swappable system fans for cooling the processor(s),
hard drives, and add-in cards. A fourth fan may be added in the fan2 position to provide
conditional cooling redundancy for system components. The system fans are mounted in a fan
assembly located in the middle of the chassis to pull cooling air through the chassis. The power
supplies contain a single fan for cooling.
1.8 Chassis Security
To help prevent unauthorized access to the system’s peripherals and control panel, an optional
key-locked front bezel can be used. The chassis also includes a preinstalled intrusion switch
that can be monitored by server management software. When the cover is opened, a switch
located on the front panel board transmits a signal to the Baseboard Management Controller
(BMC) on the server board. Through server management software, the system can be
programmed to respond to an intrusion by powering down or by locking the keyboard. At the
chassis level a variety of security options are provided.
1.9 Rack and Cabinet Mounting Options
The SR2300 chassis was designed to support 19” wide by up to 30” deep server cabinets. The
chassis comes equipped with a relay rack or cabinet mount kit that can be configured to support
front-mount or mid-mount 2-post racks and 4-post cabinets. Intel also provides an optional
sliding rail kit that is used to mount the chassis into a standard (19” by up to 30” deep) EIA-
310D compatible server cabinet.
For mounting in a regular server cabinet, the front mount brackets are attached to the front of
the chassis, and a set of rear support brackets are attached to the back end of the cabinet. This
evenly distributes the server to prevent the mounting rails on the cabinet from bending. Caution
should be used in using the front mount-only option. Even though the rail mount kit hardware
was designed to support the weight of the system, some 2-post relay racks may not, causing
the racks to fail. Only use relay racks that are specifically designed to support the weight and
stresses of a 2-post front-mount only chassis.

1.10 Front Bezel Features
The optional front bezel is made of molded plastic and uses a snap-on design. When installed,
this design provides for maximum airflow. By using light pipes, system status LEDs can be
monitored with the front bezel in the closed position.
The front bezel lock provides security for the hard drives, peripheral devices and front panel
control.

2. Power Sub-system
This section provides an overview of the SR2300 power supply sub-system. For additional
details, refer to the SR2300 Power Supply Specification. Two power supplies models are
supported in the SR2300. The first is a RPS500 1+1 redundant power supply supporting 1 or 2
TPS 500W modules. The second is the EPS2U 480W non-redundant power supply.
2.1 RPS500 1+1 power supply cage with TPS 500W SSI power
supply modules
The RPS500 power supply cage can support up to two TPW 500W SSI power supply modules
in a 1+1 configuration or a non-redundant single module configuration (1+0). The cage
incorporates dual AC inputs with two EMI filters.
A mechanical drawing for the power supply cage is provided on the following page.
