Power indicator codes for AC and DC redundant power supply unit

Each AC power supply unit (PSU) has an illuminated translucent handle and each DC PSU (when available) has an LED that serves as an indicator to show whether power is present or a power fault has occurred.

AC power supply unit status indicator/handle

Convention	Power indicator pattern	Condition
A	Green	The handle indicator lights green indicating that a valid power source is connected to the PSU and that the PSU is operational.
B	Flashing green	When updating the firmware of , the PSU handle flashes green. CAUTION: Do not disconnect the power cord or unplug the PSU when updating firmware. If firmware update is interrupted, the PSUs will not function. You must roll back the power supply firmware by using Life cycle controller. See Dell Lifecycle Controller User’s Guide at dell.com/esmmanuals
C	Flashes green and turns off	When hot-adding a PSU, the handle of the new power supply unit flashes green five times at 4 Hz rate and turns off. This indicates that the new PSU is mismatched with the PSU that is installed (in terms of efficiency, feature set, health status, and supported voltage). Use a PSU that matches the capacity of the PSU that is installed. NOTE: For AC power supplies, use only PSUs with the Extended Power Performance (EPP) label on the back. Mixing PSUs from previous generations of servers can result in a PSU mismatch condition or failure to power on.
D	Flashing amber	Indicates a problem with the power supply unit. CAUTION: When correcting a PSU mismatch, replace only the PSU with the flashing indicator. Swapping the opposite power supply unit 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 down the system. CAUTION: AC power supplies support both 220 V and 110 V input voltages with the exception of Titanium power supplies, which support only 220 V. When two identical power supplies receive different input voltages, they can output different wattages, and trigger a mismatch. CAUTION: If two power supplies are used, they must be of the same type and have the same maximum output power. CAUTION: Combining AC and DC power supplies is not supported and triggers a mismatch.
E	Not lit	Power is not connected.
