Dell APEX Cloud Platform MC-760 Hardware Requirements and Specifications

Power supply unit indicator codes

AC and DC PSUs have an illuminated translucent handle that serves as an indicator. The indicator shows if power is present or if a power fault has occurred.

The following table describes the AC and DC PSU status indicator codes.

Table 1. AC and DC PSU status indicator codesThis table describes the AC and DC PSU status indicator codes.
Power indicator codes Condition
Green Indicates that a valid power source is connected to the PSU and the PSU is operational.
Blinking amber Indicates an issue with the PSU.
Not powered on Indicates that the power is not connected to the PSU.
Blinking green Indicates that the firmware of the PSU is being updated. Do not disconnect the power cable or unplug the PSU when updating firmware.
CAUTION:If firmware update is interrupted, the PSUs will not function.
Blinking green and powers off When hot-plugging a PSU, it blinks green five times at a rate of 4 Hz and powers off. This activity indicates a PSU mismatch due 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 nodes is not supported, even if the PSUs have the same power rating. Mixing PSUs results in a PSU mismatch condition or failure to power on the system. AC PSUs support both 240 V and 120 V input voltages except for Titanium PSUs, which support only 240 V. When two identical PSUs receive different input voltages, they can output different wattages, and trigger a mismatch. 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 the opposite way, you must power off the system.
CAUTION:If two PSUs are used, they must be of the same type and have the same maximum output power.
