components.
Chassis
The major component of the kit is the chassis, which comes pre-assembled with the
exception of the server board and optional peripherals. Before adding these
devices, it is important to become familiar with the chassis both externally and
internally and the security features it provides.
/ NOTE
The following sections provide a high-level overview of the
chassis. For a more detailed, technical description, contact
your Intel representative about how to receive or gain access
to the Intel? SR2050 KDK Server Chassis Technical Product
Specification.

System Description 15
Power Supply
Within the chassis is a power supply and a power distribution board. The supply
provides 275-watts of power and is designed to minimize EMI. The supply
operates within the following voltage ranges and is rated as follows:
? 100-120 V~ at 50/60 Hertz (Hz); 4.6 A maximum
? 200-240 V~ at 50/60 Hz; 2.3 A maximum
The DC output voltages of the power supply are +5.125 V, +12 V, +3.3 V, -5 V,
-12 V, and +5 V standby. The power supply features a 24-pin main power
connector and a 6-pin auxiliary ATX power connector.
System Cooling
The chassis includes two system fans for cooling and airflow. Both fans provide
cooling for the processor(s), hard drives, and add-in cards. The power supply
contains its own built-in fan for cooling. As shown in Figure 3, two 80 mm fans
are located in the middle of the chassis to pull cooling air through the length of the
chassis.
Security
To help prevent unauthorized entry or use of the system, the chassis includes a
mechanical lock on the front bezel to prevent access to the system뭩 peripherals
and control panel. The chassis also includes an intrusion switch that can be
monitored by server management software. When the top cover is opened, the
switch transmits a signal to the server board, where server management software
processes the signal. For example, the system can be programmed to respond to an
intrusion by powering down or by locking the keyboard.
16 Intel SR2050 Chassis Subassembly Product Guide
Optional Peripherals
In addition to the slim line CD-ROM drive that comes with it, the chassis provides
for a variety of peripherals that can be added to the system. The following
describes the available options.
Hot-Swappable Hard Disk Drives
The chassis provides a hot-swap bay for the installation of up to four 3.5-inch SCSI
hard drives. A major feature of the hot swap bay is the backplane which powers
down a drive when a failure is detected and reported to the SCSI bus. When a new
drive is inserted, the power control waits a short time for the drive to become fully
seated and then applies power to the drive. The backplane provides signals to the
control panel to indicate failure status for each drive in the bay.
Either four 1-inch high or two 1-inch high and two 1.6-inch high, 3.5-inch SCAcompatible
SCSI hard drives can be installed in the bay. Drives can consume up to
17 watts of power each. Drives must be specified to run at a maximum ambient
temperature of 50 캜.
The chassis ships with four drive carriers for mounting the separately purchased
hard drives. For information on how to install these drives, refer to page 44.
Fixed Drives
The chassis provides a bay for installing one of many types of 3.5-inch fixed (i.e.
non-hot swappable) drives including a diskette drive, zip drive, tape drive, or an
additional hard drive. The chassis includes a drive tray for installing the device,
which must be purchased separately. For information on how to install a fixed
drive, refer to page 47.
