Hot-Swap Tray Front Connections
The hot-swap tray provides wires for connecting the activity LED, power
LED, SCSI ID, power, and SCSI signal. Connect the 8 pin connector to the
SCSI Address pins according to the colors shown. Connect the 2 pin con-
nector to the activity signal pins according to the colors shown.
IMPORTANT: The following is only an example. Always consult your
hard disk drive documentation or labels for the exact wiring specific to your
hard disk drive make and model.
Hot-Swap Tray Usage
Each hot-swap tray provides an aluminum carrier for a single SCSI hard
disk drive with a maximum height of 1 5/8 inch, width of 4 inches, and
length of 6 inches. The aluminum tray provides protection and maximum
heat dissipation for almost all types of high speed SCSI disk drives. The
provided cables and wires connect to the SCSI hard disk drive and screws
are needed to secure the tray to the bottom of the SCSI hard disk drive.
