Hard drive indicator codes

Each hard drive carrier has an activity indicator and a status indicator. The indicators provide information about the current

status of the hard drive. The activity LED indicates whether the hard drive is currently in use or not. The status LED indicates

the power condition of the hard drive.

Overview

Condition

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 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

appliance 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 appliance shutdown. To change from a High Output

configuration to a Low Output configuration or vice versa, you must turn off the

appliance.

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.
