RAID Backplane III - Location/Jumper

Setting the Backplane III - Address Jumper - J2

If more than one backplane is installed in your server or expansion enclosure, each backplane address jumper must have a unique setting. This setting identifies the backplane's location within the server or expansion enclosure and ensures proper operation.

Locate the three-pin address jumper (J2) on the back of the backplane.

Jumper Position	Description

E	Address for a backplane installed in Bank E
D	Address for a backplane installed in Bank D
C	Address for a backplane installed in Bank C

Setting Backplane III - SCSI ID Jumpers - J12

The SCSI ID address jumper, a pin block with four pairs of pins (J12), is located on the rear of the backplanes in banks C, D and E. When two backplanes are daisy chained in your server or expansion enclosure, the first backplane address jumper (for example, Bank C) must be set to LOW , defining the SCSI IDs as 0 through 5. The second backplane (in this example, bank D), must be set to either HI or Reverse , defining the SCSI IDs as 5 through 0, or HI, defining the SCSI IDs as 8 to D. The default, no jumper installed, is to set the addresses LO.

If the SCSI adapter supports more than eight SCSI devices per SCSI channel, the second backplane can be set to either HI or Reverse. However, if the SCSI Adapter supports eight or fewer SCSI devices per SCSI channel, the second backplane must be set to Reverse.
