same power rating. This results in a PSU mismatch
condition, or failure to power on the system.
CAUTION: If two PSUs are used, they must be of
the same type and have the same maximum output
power.
CAUTION: When correcting a PSU mismatch, replace
the PSU with the blinking indicator. Swapping the
PSU to make a matched pair can result in an error
condition and an unexpected system shutdown. To
change from a High Output configuration to a Low
Output configuration or conversely, you must power
off the system.
CAUTION: Combining AC and DC PSUs is not
supported.
Drive indicator codes
The LEDs on the drive carrier indicate the state of each drive. Each drive carrier has two LEDs: an activity LED (green) and a
status LED (bicolor, green/amber). The activity LED blinks whenever the drive is accessed.
