Chassis Features
The SC743TQ-1200B-SQ is an ATX form factor chassis that can be used as a tower
or mounted in a 4U rackmount configuration. The following is a general outline of
the main features of the SC743TQ-1200B-SQ chassis.
System Power
The 7048A-T features a single 1200W power supply. This power supply unit has
been designed to operate at a low noise level to make it ideal for use in a worksta-
tion environment.
SATA Subsystem
The SC743TQ-1200B-SQ chassis was designed to support eight SATA hard drives,
which are hot-swappable units.
Front Control Panel
The control panel on the SuperWorkstation 7048A-T provides you with system
monitoring and control. LEDs indicate system power, HDD activity, network activity,
overheat conditions and power supply failure. A main power button and a system
reset button are also included.
Note: the power supply fail LED indicates the power supply fan has failed.
Cooling System
The SC743TQ-1200B-SQ chassis has an innovative "Super Quiet" cooling design
that provides sufficient cooling at very low noise level - ideal for a workplace envi-
ronment. The chassis includes one 8-cm hot-plug PWM (Pulse Width Modulation)
system cooling fan located in the middle of the chassis and 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.
