Monitoring the power supply
The N3700 storage system power supply has four LEDs. The LEDs indicate
whether the power supply or the integrated fan module is functioning normally or
whether 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 system console.
A normal functioning power supply shows the green LED on the far left as on, with
the rest of the amber LEDs off. A power supply fault turns on the appropriate amber
LED, and causes the LED to turn off.
Location of LEDs
Each power supply is encased in a device carrier and housed at the rear of your
N3700 storage system. Figure 6 on page 22 shows the location of the power supply
LEDs.
