The following figures show the full configurations of power modules in a switch.

NOTE:

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.

AC socket complying with the local standard. To use OT terminals or cord end terminals, make power cables onsite.

2200 W AC power module

≥ 16 A

AC socket complying with the local standard. To use OT terminals or cord end terminals, make power cables onsite.

AC socket complying with the local standard. To use OT terminals or cord end terminals, make power cables onsite.

  • For 800 W power modules, select the power cables with the maximum current of larger than or equal to 10 A. For 2200 W or 3000 W power modules, select the power cables with the maximum current of larger than or equal to 16 A.

  • The power cable used by the 3000 W AC power module allows maximum current of 16 A. When the power module uses 220 V power input, the minimum voltage cannot be lower than 200 V. When the power module uses 110 V power input, the minimum voltage cannot be lower than 100 V.

  • 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.

NOTE:
  • When using 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.
  • Select appropriate power cables according to the power supply distances. If the required power supply distance exceeds the maximum power supply distance, use power distribution boxes. The power supply distance is the cable length between the power distribution frame and power module.

  • An 800 W AC power module provides a maximum output power of 800 W when the input voltage is 220 V. When the input voltage is 110 V, the maximum output power reduces to 400 W.

  • A 2200 W AC power module provides a maximum output power of 2200 W when the input voltage is 220 V. When the input voltage is 110 V, the maximum output power reduces to 1100 W.

  • 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.

  • An 800 W power module may not provide sufficient power for a chassis if the input voltage is 110 V. In this case, use a 2200 W or 3000 W AC power module as the system power module.
