ERS/FT II Disk Drive Bay
The disk drive bay is located in the front of the system behind the front panel. The purpose of the disk drive bay is to provide a location for mounting disk drives used by the computers in the system. One of three possible drive configurations may be specified at the time the subsystem is manufactured. The configuration only determines what types of disk drives the bay will accommodate. The drives themselves may be installed at the time the system is manufactured or they may be added at a later date.
All of the disk drive bay configurations support a single third-height 3.5" floppy diskette drive with the floppy drive door accessible from the front of the system. This is referred to as the "muxed floppy", and it is shared between all of the BC Series plug-in motherboards installed in the system. All configurations also provide vertical mounting locations for hard drives. Hard drive mounts are designed to accommodate either a single third-height 3.5" disk drive or two of the 2.5" mini disk drives used with the Cubix QL Series processors.
The standard disk drive bay configuration provides nine vertical drive mounts. One is for the muxed floppy drive, leaving eight locations in which to mount hard disk drives. Each hard drive mounting location will accommodate one third-height 3.5" drive or two 2.5" drives, providing for a maximum of eight 3.5" or sixteen 2.5" drives in the bay. Note that the types of hard disk drives installed may be mixed, so that 3.5" drives may be installed in some locations and 2.5" drives in others. Typically, a single 3.5" drive is installed in each location, allowing each of the eight possible BC Series plug-in motherboards installed in the subsystem to have one dedicated hard disk drive. Refer to Figure 3-1.

Drive Opening - Standard Configuration
Optional drive bay configurations may be substituted for the standard configuration. One option allows for installation of a half-height 3.5" tape drive. In this configuration, the tape drive occupies two of the vertical mounting locations provided in the standard configuration for hard disk drives, leaving only six. Therefore, six 3.5" or twelve 2.5" drives may be installed with the tape drive. Like the disk drives, the tape drive is mounted vertically in the subsystem. Access to the tape drive is via the front of the system as illustrated in Figure 3-2.

Drive Opening - Tape Option
The other disk drive bay configuration is designed to accommodate a CD ROM drive as well as a half-height 3.5" tape drive. The CD ROM drive is installed horizontally and has a 5.25" width. The tape drive is installed horizontally on top of the CD ROM drive as illustrated in Figure 3-3. These drives occupy four of the mounting locations provided in the standard configuration for hard disk drives, leaving only four. Therefore, four 3.5" or eight 2.5" drives may be installed with the tape and CD ROM drives.
Refer to Table 3 - 1 for a summary of disk drive bay configurations.
