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 confi guration. The following is a general outline of
the main features of the SC743TQ-1200B-SQ chassis.
System Power
The 7047A-73/7047A-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 workstation environment.
SAS Subsystem
The SC743TQ-1200B-SQ chassis was designed to support eight SAS or SATA hard
drives, which are hot-swappable units. (SAS is with 7047A-73 only).
Front Control Panel
The control panel on the SuperWorkstation 7047A-73/7047A-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 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.
