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.
