1.6.5.2 Disk Labels
On the disk labels, split rectangles in front of each disk’s slot are color-coded to
show the SCSI IDs for the disk. The numbers in the left (blue) half apply to the disk
in single-bus mode. The numbers in the right (yellow) half apply to the disk in split-
bus mode. As described in “Configuration Options Switch Bank” on page 1-14, the
mode is set by switch 1 in the switch bank on the front of the ESM.
As shown in
FIGURE 1-3
, the left drive label also includes a color-coded graphic along
with explanatory text to indicate which of the settings for switch 1 correspond with
the SCSI IDs. (See “ESM” on page 1-11 and “Supported Configurations” on
page 1-19 for details about single-bus and split-bus configuration.)
FIGURE 1-3
Disk Slot Labels Showing the SCSI IDs for Disks
Flashing green A disk drive in the slot is active.
Amber An application running on the host identified an error and used SAF-TE
commands to instruct this LED to display as solid amber. This LED displays, for
example, if diagnostic software running on the host cannot access the disk.
Blinking amber/green An application running on the host used SAF-TE commands to instruct this LED to
identify a disk drive by blinking amber and green.
