System Overview
Note
:
The factory standard default value of the USB ports on
your server is "Disabled". To enable it, the USB Controller feature in
the Peripheral Configuration Submenu of the BIOS Setup Utility
described in Chapter 3 "BIOS Setup Configuration Settings" must be
changed to "Enabled."
System Power
The server may be configured with up to two 450-Watt power supplies for maximum
system power of 600 Watts. Each supply has autoranging input 50/60 Hz and
automatically switches between the following input voltage ranges:
!
100-127 VAC at 50/60 Hz; 7.6 A maximum current
!
200-240 VAC at 50/60 Hz; 3.8 A maximum current
All output grounds connect to the power supply chassis and to earth ground through the
AC line cord. Each supply has:
!
Individual AC input line cord that plugs into the external side of the power supply
!
Isolating device on each DC output so that the failure of one supply does not affect
the operation of the others
!
Cooling fan integral with each power supply enclosure. The fan circuit implements
fan failure detection.
In a system, power is drawn equally from all supplies installed. In a high-access system
with two power supplies, the additional supply gives redundancy, because the load is
redistributed if one supply fails. Also with the second power supply installed all the
power supplies are now hot-swappable and can be easily installed or removed from the
server without turning system power off.
Peripheral Bays
The system supports a variety of standard PC AT-compatible peripheral devices. The
chassis includes these peripheral bays:
!
A 3.5-inch front panel bay for mounting the standard 3.5" diskette drive (supports
720 KB and 1.44 MB diskette media)
!
Two 5.25-inch removable media
front panel bays for mounting half-height 5.25-inch
peripheral devices: optional tape drives and optional additional CD ROM drive, etc.
!
A front panel bay for mounting the standard CD-ROM drive.
!
One standard and one optional hot-swap SCSI hard disk drive bay for mounting up
to ten SCSI hard disk drives (five disk drives per bay) in easily removable drive
carriers. Each drive has a set of two lights to indicate the fault or other status: power-
on (green LED), activity (green LED, and fault (yellow LED).
Note:
The SCSI hard disk drive bays contain a hot-swap back
panel that require an 80-pin single connector attachment (SCA)
connector on the drives that you install.
