Monitoring the power supply
LEDs on the power
supply The power supply has four LEDs. The LEDs indicate whether the power supply
or the integrated fan module is functioning normally or there are problems with
the hardware. You can also identify any hardware failure associated with the
power supplies from the error messages displayed on your storage controller
console.
Location of LEDs Each power supply, which contains two LEDs, is encased in a device carrier and
housed at the rear of the disk shelf. The following illustration shows the location
of the power supply LEDs.
Note
The PSU status LED is green. The other three LEDs are amber. See “ LED status
on the modules ” on page 18 for an illustrated explanation of how the LEDs
