Features:

Optional power supply module for EdgePower 54V 150W, which has a secondary PSU module bay. The module is hot-swappable and may works as backup PSU or for increasing the DC output power to 300W. The secondary PSU may be configured as a backup PSU. In backup mode, the secondary PSU remains inactive and offline. If failure of the primary PSU is detected, the secondary PSU automatically activates to supply continuous power.
