1-3 Chassis Features
The following is a general outline of the main features of the SC743T-645 chas-
sis.
System Power
The SC743T-645 features a single 645W power supply. The system must be shut
down and the AC power cord removed before replacing or performing any service
on the power supply unit.
Serial ATA Subsystem
The Serial ATA subsystem supports up to six Serial ATA drives. The Serial ATA
drives are hot-swappable units and are connected to a backplane that provides
power and control.
Note: The operating system you use must have RAID support to enable the hot-
swap capability of the Serial ATA drives.
Front Control Panel
The chassis' control panel provides you with system monitoring and control. LEDs
indicate system power, HDD activity, network activity, system overheat and power
supply failure. A main power button and a system reset button are also included.
I/O Backplane
The SC743T-645 is an ATX form factor chassis that may be used in either a tower
or a 4U rackmount confi guration. Up to seven PCI expansion slots can be accom-
modated in the chassis.
Cooling System
The SC743T-645 chassis has an innovative cooling design that includes four 8-cm
hot-plug system cooling fans located in the middle section of the chassis. These
are PWM (Pulse Width Modulated) fans, which allows their speed to be set with an
option in BIOS. The power supply module also includes a cooling fan.
