Power Supply
The system contains one auto-sensing 570-watt power supply at an operating frequency
of 50/60 Hz.
A second optional power supply may be added as part of a fault-tolerant hot-swap
design. With two power supplies installed, in the unlikely event of a power supply
failure, the load is transferred to the remaining power supply without interruption to
normal operation. In this case the faulty power supply can be replaced without
powering down the system.
there are two power supplies installed.
The power supplies are designed to comply with existing emission standards and
provide sufficient power for a fully loaded system configuration.

disk drive bays for installing up to six SCSI hard disk drives.
■ The SCSI hard disk drive bays for installing up to six SCSI hard disk drives.
The SCSI disk drives can be easily installed or removed. The drive carrier allows you
to access to disk drives from the front of the system. If disk drives are provided with
RAID configuration within the system, a disk drive can be swapped with another
without power interruption in the system (hot-swap).
