Thunder i7520 / Thunder i7520R
2.3 – Chassis/Enclosure Considerations
Motherboard size
The printed circuit board size is 13" (W) x12" (L).
Motherboard and CPU Heat-sink Mounting Holes
There are nine motherboard-mounting holes and eight CPU heat-sink mounting
holes on the 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.
S5360/S5360-1U supports Intel's CEK (Common Enabling Kit) for securing Intel's
®
Xeon 800 MHz FSB processors and processor cooling heat-sinks 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 should be also considered for choosing a proper enclosure.
2.4 – Power Supply Considerations
Power connectors
Both Thunder i7520 S5360 and Thunder i7520R S5360-1U boards support
EPS/12V power supply unit (PSU) with two power connectors listed below.

Split processor power planes
Both Thunder i7520 S5360 and Thunder i7520R S5360-1U boards support dual
Intel's 800 MHz FSB Xeon
processor. (Check Intel's web for your processor specifications.) By following SSI
EEB v3.51 specifications, S5360/S5360-1U 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.
