Figure 9 DC PSU status indicator (continued)

DC PSU status indicator

Table 29 DC PSU status indicator codes

Power indicator codes

Green

Blinking amber

Not illuminated

Blinking green

Condition

A valid power source is connected to the PSU, and the PSU is

operational.

Indicates a problem with the PSU.

Power is not connected to the PSU.

When hot-plugging a PSU, the PSU indicator blinks green. This

indicates that there is a PSU mismatch regarding 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 systems based on 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

on the system.

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

conversely, 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.
