1.3.2 DVD ROM Drive
In the i2000 system, the DVD ROM drive in the peripheral bay consists of an IDE device.
1.3.3 Hard Drive Bay
The hard drive bay is designed for 3.5-inch-wide hard drives. It can accommodate up to
five- (5) 1-inch-high or three- (3) 1.6-inch-high drives.

Power Supply
The chassis is configured with a single, 800 W power supply. It is capable of providing
full rated output power over a range of input voltages, 100-240 VAC. The power supply
features automatic Power Factor Correction (PFC), and is connected to the system
boards using the following connectors:
•
A 24-pin baseboard connector pro3.3 V
dc
and +5 V

•
A 22-pin baseboard connector with +3.3 V

•
A 6-pin connector for the processor Power Pod with an output voltage of 12 V
dc
•
A 16-pin connector with outputs of +5 V

for peripherals
For ease of replacement, the connectors can be disconnected from the power supply
and the power supply replaced without removing the system boards or unhooking any
connectors from the boards.

System Cooling
Support for eight- (8) fans within four- (4) separate zones (regions of the system) is
provided for the following configuration:
•
Zone 1 - Processor
: two- (2) fan headers for two- (2) 120-mm fans.
•
Zone 2 - Memory
: one- (1) fan header for one- (1) 80-mm fan.
•
Zone 3 - I/O
: two- (2) fan headers for one- (1) 92-mm and one- (1) 60-mm fan.
•
Zone 4 - Exhaust
: three- (3) fan headers for three- (3) 80-mm fans,
but only
one- (1) is populated in the reference system configuration
.
i2000 utilizes three- (3) wire fans; two- (2) wires provide power, another provides the fan
tachometer output. Utilizing a three-wire fan allows the system to monitor the fan speed
and control the speed via the power source with sensing from a thermister (on-board or
remote).
