The following figures show the full configurations of power modules in a switch.
If more than one power module is installed in a switch, you can connect the power modules to the same power source or different power sources. It is recommended that you connect the power modules to different power sources to improve power reliability.
- Figure 5-26 shows the 1+1 redundancy of system power modules in a switch.
- Figure 5-27 shows the 2+2 redundancy of system power modules in a switch.
- Figure 5-28 shows the 3+3 redundancy of power modules.

- For 3000 W AC power modules, select the power cables with the maximum current of greater than or equal to 16 A.
Each AC power module must be connected to an independent circuit breaker.
The current rating of the circuit breaker cannot be smaller than the maximum current allowed by the power cable.
Select appropriate power cables according to the power supply distances. The power supply distance is the cable length between the power distribution frame and power module.
A 3000 W AC power module provides a maximum output power of 3000 W when the input voltage is 220 V. When the input voltage is 110 V, the maximum output power reduces to 1500 W.
To use the N+N redundancy mode, equally divide the power modules into two groups and connect the two groups of power modules to two independent power supply systems. This configuration provides redundancy of power supply systems to enhance system reliability.
