Power indicator codes
Condition
Blinking green
When hot-plugging a PSU, the PSU indicator blinks green. This indicates that there is a PSU
mismatch with respect to efficiency, feature set, health status, or supported voltage.
CAUTION: If two PSUs are installed, both the PSUs must have the same type of label; for
example, Extended Power Performance (EPP) label. Mixing PSUs from previous
generations of PowerEdge servers is not supported, even if the PSUs have the same
power rating. This results in a PSU mismatch condition or failure to turn the system on.
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 turn off the system.
CAUTION: If two PSUs are used, they must be of the same type and have the same
maximum output power.
CAUTION: Combining AC and DC PSUs is not supported and triggers a mismatch.
Drive indicator codes
Each drive carrier has an activity LED indicator and a status LED indicator. The indicators provide information about the current
status of the drive. The activity LED indicator indicates whether the drive is currently in use or not. The status LED indicator
indicates the power condition of the drive.
