12 About Your System
NOTICE: This system does not support user-customizable operating modes. Therefore, the split mode LED and
enclosure mode switch are not functional. However, if additional expansion enclosures are daisy chained to your
system, the enclosure mode switch on the RAID array enclosure must be in single-mode position. For more
information, see "Cabling Your RAID Enclosure" on page 21.
Physical Disk Carrier LED Indicators
Each physical disk carrier in your enclosure has two LEDs: an activity LED (green) and a bicolor
(green/amber) status LED (see Figure1-3). The activity LED flashes whenever the physical disk is
accessed. Table1-3 lists the flash patterns for the status LED.
