Physical Disk Carrier LED Indicators

Each physical disk carrier in your enclosure has two LEDs: an activity LED
(green) and a bi-color (green/amber) status LED (see Figure 1-3). The
activity LED flashes whenever the physical disk is accessed. Table 1-3 lists the
flash patterns for the status LED.
Condition
When lit, indicates the enclosure is in split-
mode configuration; otherwise, the enclosure is
in unified mode. For more information, see
"Unified Mode and Split Mode" on page 16.
When set in its uppermost position at power
on, the enclosure is configured in unified
mode; when set in its lowermost position at
power on, the enclosure is configured in split
mode.
NOTE:
This switch must be set prior to power on.
Changing the switch setting after power on will
have no effect on enclosure configuration until
the system is power cycled.
