Power indicator codes
Condition
CAUTION:
When correcting a PSU mismatch, replace only the PSU with the blinking indicator.
Swapping the PSU to make a matched pair can result in an error condition and unexpected
system shutdown. To change from a high output configuration to a low output configuration or
vice versa, you must power off the system.
CAUTION:
AC PSUs support both 240 V and 120 V input voltages with the exception of Titanium
PSUs, which support only 240 V. When two identical PSUs receive different input voltages, they
can output different wattages, and trigger a mismatch.
CAUTION:
If two PSUs are used, they must be of the same type and have the same maximum
output power.
Drive indicator codes
The LEDs on the drive carrier indicates the state of each drive. Each drive carrier in your system has two LEDs: an activity LED (green) and
a status LED (bicolor, green/amber). The activity LED flashes whenever the drive is accessed.
