backplane with SAF-TE. The SCSI drives are also hot-swap units. A RAID
controller card can be used with the SCA backplanes to provide data secu-
rity.
Note: The operating system you use must have RAID support to enable the
hot-swap capability of the SCSI drives.
Front Control Panel
The SC743S1-R760/SC743S1-650's control panel provides you with system
monitoring and control. LEDs indicate system power, HDD activity, network

and a system reset button are also included.
I/O Backplane
The SC743S1-R760/SC743S1-650 is an Extended ATX form factor chassis
that can be used either as a tower or as a 4U rackmount unit.
backplane provides six motherboard expansion slots, one COM port, a VGA
port, two USB 2.0 ports, PS/2 mouse and keyboard ports, a parallel port
(available with the 7044H-82R/7044H-82 only) and two gigabit Ethernet

The SC743S1-R760/SC743S1-650 chassis has an innovative cooling design
that includes four 8-cm hot-plug system cooling fans located in the middle
section of the chassis and two 8-cm hot-plug rear exhaust fans.
power supply module also includes a cooling fan.
supply fans operate continuously.
A setting in BIOS (see p. 7-18) is used to control the system fan speed.
This setting uses voltage control to allow fans to run at different speeds.
[The recommended setting for the 7044H-82R/7044H-X8R/7044H-82 is "3-
pin (Server)".]
The SCSI drives are connected to a single-channel SCA
