You can install, remove, or replace a power supply on the ExtremeCloud IQ Controller E3125. For information on installing a power supply, see Connect a Power Source.
The controller ships with one installed power supply. But you can purchase additional redundant power supplies separately. The purchase order part number is PSI-1300W-APL.
Each power supply has a single bi-color LED to indicate power supply status. The following table describes the indicator patterns.
| Power supply condition | LED indicator |
|---|---|
| Output On and OK | Green |
| No AC power to all power supplies | Off |
| AC present and only 12VSB On (PS Off) or PS in cold redundant state | 1 Hz blinking green |
| AC power cord unplugged or AC power lost, with a second PS in parallel still with AC input power | Amber |
| Power supply warning events where PS continues to operate - high temperature, high power, high current, and slow fan | 1 Hz blinking amber |
| Power supply critical event causing a shutdown, failure, OCP, OVP, and fan fail | Amber |
| Power supply firmware update | 2 Hz blinking green |
