System Components Hot-Swap Trays Maximum uptime in a server requires devices that can be easily replaced or "swapped. " The main hard disks are mounted in internal hot-swap trays for easy replacement. To remove the tray, unlock the tray and pull on the handle. A lock secures the handle and switches on or off the power to the hard drive. II. Components Hot-Swap Trays Removing or inserting the hot-swap tray Hot-Swap Tray (8 Total) Hot-Swap Tray Keylock Positions Lock/ Power On Unlock/ Power Off Hot-Swap Tray Interface The front of the hot-swap tray provides a keylock in order to switch the power on, which also locks the handle, and switch the power off, which also releases the handle. Two LEDs provide information on the power and activity status of the hard disk drive. When power is received by the hot-swap tray's connector board, the power LED will light. When data is written or read to or from the contained hard disk drive, the activity LED will flash proportional to the amount of data transferred.

System Components 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. SCSI Cable Aluminum Tray Activity LED (ALED) Power Connector Screw Holes SCSI ID Hot-swap tray and its connectors 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 connector 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.

System Components Hot-Swap Tray Connector Board The connector board is mounted on the hot-swap tray to interface with the SCSI backplane in the chassis. The connector board combines all the signal and power into one docking connector for a simple hot-swap unit. KEY SLED (not used) PLED ALED_IN (not used) SCSI_ID II.

PLED: These 2 pins connect to the power LED on the tray's front panel to show when the connector board receives power. SCSI_ID: These 8 pins connect to the hard disk drive's SCSI address pins to set the SCSI ID number of the hard disk drive. [. . . ] Each LPT port is configured to use a different IRQ and address assignment. PCI Bus (Peripheral Component Interconnect Local Bus) PCI bus is a specification that defines a 32-bit data bus interface. PCI is a standard widely used by expansion card manufacturers.
