Connecting the RPS Cable and AC Power Cord



When performing this task, observe all of the precautions listen in Safety Considerations for Installing Power Supplies.

The redundant power supply is connected to a switch using a 1-meter RPS cable.

To connect a redundant power supply, proceed as follows:


No change in switch configuration is necessary for this installation.
  1. Connect one end of the RPS cable to the redundant power supply connector at the rear of the RPS.
    Then connect the other end of the cable to the redundant power supply connector on the switch.

    See the following figures.

    RPS and AC Power Cord Connections
    1 = Switch 4 = Switch Redundant Power Supply connector (location varies depending upon switch)
    2 = High speed RPS cable (1 meter) 5 = AC power cord (type varies depending on country)
    3 = RPS Redundant Power Supply connector 6 = AC power outlet with ground connection (type varies depending on country)
  2. Connect the AC power cord to the AC input power connector on the RPS shown in the figure above.
  3. Plug the AC power cord into the main AC power outlet.

The green Power LED on the front of the RPS will illuminate to indicate a successful connection. On certain switches, an LED indicator on the switch will show that a redundant power supply is now in operation.

If the green power LED is not lit, proceed as follows:

  • Check the AC power cord connection at the AC power source and make sure the power source is within specification.
  • Check the AC power connection to the power supply.
  • Swap the AC power cord with one that is known to work properly.

If the green LED remains off, contact Extreme Networks support.
