Checking the Binary SCSI LEDs
2. Locate the binary SCSI LEDs (see
FIGURE 5-2
).
3. Use
TABLE 5-2
or the pullout card attached to the system to determine which SCSI
IDs are assigned to the drives in the storage enclosure.
The disk drive SCSI ID numbers are assigned in sequences of three numbers in a
row. The first number in the sequence is the base address. The base address is the
number used to set the SCSI toggle switch on the back of the storage enclosure and
is represented in binary format on the top row of disk drive LEDs on the front of the
storage enclosure. See “Connecting the Cables” on page 47 for more information on
how to set the SCSI IDs.
Note – The shaded rows of the table represent SCSI ID sequences that cannot be
used because SCSI ID 7 is assigned to the SCSI controller. Some servers reserve SCSI
ID 6 for use by CD drives and IDs 0 and 1 for internal drives.
