Safety Instructions
To maximize user safety and ensure correct device operation, all instructions con-
tained in this section should be read carefully.
• Take care that there are no cables, particularly mains cables, in areas where
persons can trip over them.
• Do not use a mains connection in sockets shared by a number of other power
consumers. Do not use an extension cable.
• Only use the mains cable supplied.
• The unit is completely disconnected from the power source only when the
power cord is disconnected from the power source. Therefore the power cord
and its connectors must always remain easily accessible.
• Do not set up the device in the proximity of heat sources or in a damp location.
Make sure the device has adequate ventilation.
• All plugs on the connection cables must be screwed or locked to the chassis
housing.
• The device is designed to be used in horizontal position only.
• Repairs may only be carried out by a person authorized by Themis Computer.
• If extensions are made to the device, the legal stipulations and the device spec-
ifications must be observed.
• The CoolShell CS-3U power cord(s) should be disconnected before removing
or replacing any CoolShell CS-3U components (Blade or Module).
Caution: It is important that the user observe all warnings and instructions that
are on the device and contained in this manual.

Themis Computer
Preface
This document—CoolShell CS-3U Installation Manual— is intended for an experi-
enced system administrator with a knowledge of both networking and high-speed
server systems. It provides instructions on how to install, configure, power up, and
boot the CoolShell CS-3U (see photo below), which consists of the following 1RU-
high components—all contained in a 3RU-high subrack mountable within a 19”
RETMA rack:
• One CPU (Processor) Blade based on two Intel® 64-bit Quad-Core Xeon™
5400-series CPUs—supports PCI-Express, power/reset, clock/I2C, and two
audio channel connectors, as well as a reset button and two status LEDs
• One I/O Blade—supports three PCI-Express (x8) NVIDIA 3700 graphics
cards and six USB 2.0 I/O ports
CoolShell CS-3U Components (Subrack Cover Removed)

xvi Themis Computer
CoolShell CS-3U Installation Manual
• One Media Module—supports 8 copper Gigabit Ethernet ports (RJ45)—7 of
which can be connected using optical-fiber ports (SFP) instead of copper, 6
USB 2.0 ports, one DVD/CD combo drive, and two storage media (rotating
disk drive or solid-state flash drive in any combination), one fixed and one
removable from the front.
• Two load-sharing, hot-swappable AC Power Supplies, each providing 850
watts of output power.
Each of the CoolShell CS-3U components is shown in the illustration on the follow-
ing page, with a generalized CoolShell CS-3U interconnection flow diagram shown
on the page after that.
Product Summation
The 3RU-high (5.25”) CoolShell CS-3U subrack has been designed to fit into a stan-
dard 19” rack and has all of the benefits of Themis scalable server systems based on
Themis rugged enterprise server (RES) and “CoolShell” technology; namely:
• Minimum space, weight, and power consumption
• Modularity—easy to maintain and upgrade
• Environmentally robust
—withstands up to 25G shock and vibration
—operates at up to 50°C temperature
—CPU electronics protected from dust and dirt
—light-weight construction
—reduced electromagnetic radiation emission
Because the CoolShell CS-3U is rugged enough to withstand extreme shock (up to
25G), temperature (up to 50°C), and EMI, it is highly suitable for such demanding
markets as the military, aerospace, and telecommunications industries.
An overview of CoolShell CS-3U design and specifications is given in Chapter 1,
"Overview and Specifications", of this manual.
