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.
Split mode LED
(green) 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.
