Internal Structure

The housing is symmetrically divided into left and right panels. The
system internal components are accessible through the panels.
Left Panel
The main part of the left panel houses the system board, memory
board, and expansion boards. On the rear end of the left panel are
the keyboard, mouse, video, parallel, and serial ports, and the slot
openings for installation of EISA and PCI expansion boards.
The upper front section of the left panel accommodates a 3.5-inch
and three 5.25-inch drives while the lower section holds the seven
hot-swappable SCSI drive trays. These devices on the front section
are externally accessible. Right behind the drives is a seven-slot
SCSI backplane board that connects the drives to the SCSI interface.
Figure 3-2 shows the system components on the left panel of the
system housing.
