Adding a Redundant Power Supply

Perform the following procedure to add a redundant power supply to a system that is already in operation.
➢ To add a redundant power supply
1. Remove power from the primary power supply to the RX3i CEP carrier
2. Remove the power terminal block from the carrier.
3. Without disturbing the primary power supply input lines, connect the redundant power supply
input lines to the power terminal block.
4. Insert the power terminal block into the Input Power connector.
5. Apply power to the redundant power supply. The PWR2 LED on the RX3i CEP carrier should turn
on.
6. Apply power to the primary power supply. The PWR1 LED on the CEP Carrier should turn on.

Replacing a Redundant Power Supply

If two power supplies are applied to the RX3i CEP Carrier, the RX3i CEP will continue to operate without
disruption if one of the power supplies fails or is turned off. If the power sources can be turned off
independently of each other, either one can be removed or replaced without disrupting system operation.
Note: When replacing a power supply that is connected to a powered-up CEP Carrier,
disconnect and connect the power cable only from the power supply that has power
removed. Do not attempt to perform these operations on the input power terminal block.
➢ To replace a redundant power supply
1. Check the PWR LEDs on the RX3i CEP carrier to be sure that the input source that is not being
removed is currently supplying power.
2. Remove power from the power supply that is to be removed.
3. Wait until the PWR LED for the power supply that is being removed goes off.
4. Remove and replace the power supply that is powered off.
5. Apply power to the power supply and confirm that the corresponding LED is on.
