Chapter 2 : Choose Proper Parts F o r Your System
2.3 – Chassis/Enclosure Considerations
§
Motherboard size
The printed circuit board size is 1 3" (W) x12 " (L).
§
Motherboard and CPU Heat -sink Mounting Holes
There are nine motherboard- mounting holes and eight CPU heat -sink mounting
holes on this board design. The motherboard and CPU mounting hole pattern
follows SSI EEB v3.51 (A Server System Infrastructure specification for Entry
Pedestal Servers and Workstations) specifications. Ensure that your chassis
supports those 9 motherboard-mounting holes to secure the motherboard.
Thunder i7522/S5362 supports Intel's CEK ( Common Enabling Kit ) for securing
Intel's Xeon 800 MHz FSB processors and processor cooling kits in the chassis.
Two CEK springs for the dual processors are pre - assembled with the motherboard
or enclosed in the motherboard accessory package. The CPU heat -sinks must be
mounted down to the chassis base pan with stand -offs. Any additional chassis
standoffs, besides the 9 motherboard- mounting holes and 8 CPU heat -sink
mounting holes, should be removed to preventing from short -circuit or motherboard
damage.
§
Others
As a system integrator, the air -flow/thermal, EMI/EMC, shock/vibration, and system
packing shoul d be also considered for choosing a proper enclosure.
2.4 – Power Supply Considerations
§
Power connectors
The Thunder i7522 S5362 board supports EPS/12V power supply unit (PSU) with
two power connectors listed below.

§
Split processor power planes
Thunder i7522 S5362 board supports dual Intel's 800 MHz FSB Xeon processors,
which could reach up to 140 Watts per processor. (Check Intel's web for your
processor specifications.)
i7522/S5362 is designed with two separate voltage regulator circuits to provide the
power for both onboard processors in separate power rail. Using a power supply
with a combined CPU power plane from the CPU power connector, is not allowed
and may cause system failed to power up or a damage to power supply.
