Features

The hot plug ultra-wide SCSI backplane subsystem consists of a BP-W8 backplane and drive trays that support wide SCSI hard drives. It is specifically designed for a tower housing (IDUN) and accommodates up to eight SCSI drives.

The backplane subsystem has the following major features:

Hot plug feature that allows replacement of a defective hard drive even while the system is in full operation

Two LEDs on the SCSI drive front panel to indicate power and drive failure

Supports ultra-fast/wide (16-bit) devices

Allows “split” and “combine” SCSI-channel configurations

Fixed 2.85-volt and controlled impedance of 90 ~ 110 ohms for more stable hard disk performance (For ultra SCSI, the impedance is 90 ±10%)

Supports other external SCSI devices that are not directly connected to the backplane board
