Hot-Swap Tray Usage

Each hot-swap tray provides an aluminum carrier for a single SCSI hard disk drive. 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.
