1-6 System Overview
Power Supply
The ATX300 watt power supply is switch-selectable for 115 or 230 Vac at an operating
frequency of 50/60 Hz. It is designed to comply with existing emission standards and
provides sufficient power for a fully loaded system configuration. The power supply
voltage selection switch is factory set to 115Vac for systems used in the United States;
it is set to 230Vac for systems used in Europe.

Peripheral Bays
The system supports a variety of standard PC AT-compatible peripheral devices. The
chassis includes these peripheral bays:

Your system includes either four standard SCSI hard disk drive bays for
mounting up to four drives or six hot-swap drive bays for mounting up to six
drives in easily removable drive carriers.

Note:
The hot-swap SCSI hard disk drive bays contain a hot-
swap back plane that require an 80-pin single connector attachment
(SCA) connector on the drives that you install.

SAF-TE Logic
Note:
SAF-TE Logic is in systems that include the hot-swap
SCSI disk drive cage. SAF-TE Logic is not available in systems that
include the standard SCSI disk drive cage.

The SCSI backplane includes SAF-TE (SCSI Accessed Fault Tolerant Enclosure) logic
that provides an interface to the disk subsystem that supports status signals, hot
swapping drives, and enclosure monitoring.
that provides an interface to the disk subsystem that supports status signals, hot
swapping drives, and enclosure monitoring.
The transport mechanism for the standardized alert detection and status reporting is the
SCSI bus. Disk drives, power supplies, cooling fans, and temperature are continually
monitored and the conditions then reported over the SCSI bus to the system. When used
with RAID management software the user can be alerted of impending or imminent
disk conditions requiring attention. This allows the user to react to conditions that could
normally go unnoticed until data loss.
