Power Supplies; Peripheral Bays - NEC Express5800/120Rd-2 Service Manual

Power Supplies

The power supply consists of the power supply bay and one power supply module. A second
power supply module can be purchased to provide a redundant, 1+1 system. With either
configuration, the power supply provides 350 watts of power and is designed to minimize EMI.
The power subsystem supports implementation of remote management features including remote
enable that permits power to be activated from a variety of sources.

Peripheral Bays

Your server supports a variety of standard PC AT-compatible peripheral devices. The chassis
includes these peripheral bays:
An optional removable media front panel bay for mounting a half-height 3.5-inch
!
peripheral device such as an optional tape drive.
Depending on your configuration, your server includes either six or seven hot-swap
!
SCSI hard disk drive bays for mounting hard disk drives installed 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.
– The flex bay can be used with either the standard CD-ROM/FDD module or a seventh
hot swappable SCSI HDD.
The CD-ROM/FDD module may only be inserted or removed from the flex bay when
system power is turned off. The CD-ROM/FDD module is NOT hot swappable. The
standard 3.5-inch diskette drive supports 720 KB and 1.44 MB diskette media.
– The chassis includes two 80-mm non-hot-swappable system fans for cooling the
processor(s), hard drives, and add-in cards. The system fans are mounted in a fan
assembly located in the middle of the chassis to pull cooling air through the chassis.
The power supply contains a single fan for cooling.
