Two-backplane configuration

In a two-backplaneconfiguration:

•the upper SCSI interface of the first backplane connects to the SCSI card

•the lower SCSI interface connects to the upper SCSI interface of the second backplane

•a SCSI multi-mode terminator (LVD/SE) is placed on the lower SCSI interface of the second backplane

First backplane

Power connectors

(connect power plugs from the power supply)

Second backplane

Fan connector (for HDD fan)

SMBus connector (upper 6-1 pins)

(connects the SMB cable from the motherboard)

SMBus connector (lower 6-1 pins)

(connects the SMB cable to the second backplane)

68-pin SCSI connector

(connects the SCSI cable from the SCSI card)

68-pin SCSI connector

(connects the SCSI cable to the second backplane)

SMBus connector (upper 6-1 pins)

(connects the SMB cable from the first backplane)

Power SMBus connector (lower 6-1 pins)

(connects the SMB cable from the power supply, if available)

68-pin SCSI connector

(connects the SCSI cable from the SCSI card)

68-pin SCSI connector

(with SCSI multi-mode terminator)
