The U1981 can be configured with dual power modules. By default, there is a single power supply module, which is located in slot 2 of the power supply. When configured with dual power modules, the following functions are available:
•Supports current sharing and backup
During normal operation, multiple power modules can share the load with their own output current; When a power module stops working, other power modules play a backup role and assume their normal power supply tasks.
• Support hot swapping
Without turning off the power supply of the whole machine, the power module can be directly added at the empty slot of the distribution box; In the case of redundant backup of the power supply, a power supply module can be unplugged directly without affecting the normal operation of the device
