Additional details are given in Appendix C, "Technical Reference."
Chassis
The server system’s electro-galvanized metal chassis minimizes EMI/RFI. The
chassis contains:
auto-ranging 525 watt power supply/fan unit that automatically switches
between 110 Vac and 220 Vac
two variable-speed hot-swap fans for interior cooling, with speed
determined by interior air temperature and number of installed hard
drives
standard 3 1/2-inch diskette drive bay for the installed 1.44-MB diskette
drive
four standard 5 1/4-inch bays for mounting half-height peripheral
devices (CD-ROM, diskette drive, tape drive)
all configurations except base ship with a CD-ROM drive installed in the
bottom slot
six hot-docking bays for mounting SCSI-2 SCA 3 1/2-inch full height
hard disk drives
all configurations except base ship with one or two 2-GB hard disks
installed in the hot-docking bay
ten I/O expansion slots (slot closest to bottom of chassis has no
corresponding connector on the system board).
Two captive thumbscrews secure the removable metal door behind the lower plastic
front door to the chassis. The cover provides proper air-flow and easy access to the
hot-docking bays for hot-swapping SCSI-2 SCA hard disk drives in and out of the
server. The removable side cover, attached to the chassis with four screws, provides
proper airflow and easy access to the system board. You can secure the cover to the
chassis and the hot-docking bay metal door to the chassis with padlocks (not
provided). Figure 1-2 shows the major system components.
SCSI-2 Single Connector
Attachment (SCA)
Compatible Backplane
Provides a continuous fast/wide SCSI bus for access to all
hot-swap drive bays. Allows SCSI-1
(5 MB/sec), fast/narrow SCSI-2 (10 MB/sec), or fast/wide
SCSI-2 (20 MB/sec) data transfers to the hard drives.
