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.
