3.5Peripheral Bay and Front Panel

The peripheral bay is a sheet metal enclosure with features to mount the hot-swap SCSI hard disk drives, 5¼-inch device, and an optical drive. The SCSI Backplane Board has slots on it that slide into hooks on the peripheral bay. A plunger and captive thumbscrew secure the SCSI Backplane Board and Front Panel I/O Board to the peripheral bay.

3.5.1 Hot-Swap Hard Disk Drive Carrier

The hot-swap hard disk drive carrier is an assembly that provides guides for installing hard disk drives. The carrier has an integrated light pipe to transfer the LED indicator from the SCSI Backplane Board to the front of the drive carrier and an insertion/extraction mechanism. The hard drive bezel can be customized to meet integrator-specific industrial design requirements, by changing the color and imprint.
