Intel© LB440GX 2U Rack Server Chassis TPS Rev 1.0 7 Hot-Swap SCSI Subsystem The Intel® LB440GX 2U rack server chassis has two independent, identical hot-swap backplanes. Each backplane supports two Ultra2 SCSI hot-swappable drives. Two configurable switches on the back of each backplane (see Figure 11) determine the identification of each drive. The backplanes are then daisy chained with a standard 68-pin Ultra-2 SCSI cable. The hot-swap SCSI subsystem supports the following features: § Hot-swapping of Ultra-2 SCSI drives, that allows connection of SCSI devices while the power is on. § Full dual mode LVD operation, compliant with Fast, Ultra and Ultra-2 SCSI bus operation. 7.1 Subsystem Purpose The Intel® LB440GX 2U rack server chassis hot-swap SCSI backplane performs the tasks associated with hot-swappable SCSI drives. The backplane design allows for: § Four high density 68 pin connectors for four LVD Ultra-2 compatible SCSI drives § Active termination on SCSI bus § Per-drive power control, including automatic slot power down upon drive removal 7.2 Abstract The Intel® LB440GX hot-swap SCSI backplane is made up of the following functional blocks: § SCSI Bus with Ultra-2 high density LVD 68 pin drive connectors, and active terminators § SCSI drive power control § Configuration jumpers 10
