Hot Swap Backplane (FRU No. 06H8629):
J12 Backplane SCSI ID Jumper Settings:
The Backplane 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 the enclosure, the first backplane address jumper (for example, Bank C) must be set to LO, defining the SCSI IDs as 0 through 5. The second backplane (in this example, bank D), must be set to either
Reverse, defining the SCSI IDs as 5 through 0, or HI, defining the SCSI IDs as 8 through D. The default, no jumper installed, is to set the addresses to LO.
If the SCSI adapter supports more than eight SCSI devices per SCSI channel, the second backplane can be set either HI or Reverse. However, if the SCSI adapter supports eight or less SCSI devices per channel, the second backplane must be set to Reverse.
The following jumper settings are for SCSI ID jumper J12.
Hot Swap Tray (FRU No. 06H8631, 07H0774):
Notes:
1. The following trays are shown with drives installed.
2. Each hot-swap drive installed must have a Hot Swap Drive Tray attached.
The Hot Swap Drive Tray for the expansion enclosure has a small switch that stops the movement of the disk drive. The tray also provides two LEDs (one green and one amber) to indicate the current state of the drive and tray. The following table summarizes the LED states on the hot-swap tray and their meanings.
