Fan modules

The appliance includes three fan modules. Each fan module contains an individual cooling fan with an LED in each fan module:
  • If the amber LED is lit, there is a problem with the fan module.
  • If the amber LED is not lit, the fans are operating normally.

The speed of the fans are dependent on the temperature of the appliance. As the temperature increases, the fan speed increases to maintain a balanced temperature for the appliance.

Power supply modules

The appliance is powered by two redundant power supply modules. A single power supply module can supply enough power to support appliance operations. The power supply modules can be hot-swapped, so you can replace a single power supply module without powering down the appliance. Each power supply module contains an LED:
  • If the amber power LED is lit, the power supply has an error.
  • If the LED is not lit, the power supply is working as expected.
Note: When you press the power button to turn off the appliance, there is still electrical current flowing to the device. To completely stop all electricity to the appliance, unplug all power cords.
