I/O Backplane
The SC743TQ-865B-SQ is an ATX form factor chassis that can be used as a tower
or mounted in a 4U rackmount confi guration. The I/O backplane provides seven
expansion slots, one COM port, four USB 2.0 ports, PS/2 mouse and keyboard
ports, two Gigabit Ethernet port(s) and 7.1 HDA ports.
Cooling System
The SC743TQ-865B-SQ chassis has an innovative "Super Quiet" cooling design
that provides suffi cient cooling at very low noise level - ideal for a workplace envi-
ronment. The chassis includes two 8-cm hot-plug PWM (Pulse Width Modulation)
system cooling fans located in the middle of the chassis. A 9-cm PWM exhaust fan
is also located at the rear of the chassis.
The power supply has two fans for redundancy; if one fan fails the other will incease
its rpm to compensate. This may cause the system to run louder than usual. See
details in Chapter 6.
