AT-PWR4 Auxiliary Power Supply Features

The Allied Telesis AT-PWR4 offers maximum protection against service

interruption. The AT-PWR4 may be installed with the AT-MCR12 fully

populated and on line. In service, the AT-PWR4 provides automatic load

balancing for one or two power supplies. If a power supply should fail, the

green power indicator goes out, and on-the-fly switching transfers the entire

load to the auxiliary power supply unit. Once a replacement is obtained, it can

be installed (hot swapped) without requiring the AT-MCR12 to be powered

down.

Reviewing Safety Precautions

Please review the following safety precautions before installing the AT-PWR4.

Installing the AT-PWR4 Auxiliary Power Supply

To install an AT-PWR4 power supply into an AT-MCR12 chassis, perform the

following procedure:

1. Remove the two screws that secure the blank plate that covers the

auxiliary power supply bay. The blank plate comes off revealing the

empty bay as shown in Figure 2. Keep the blank plate and screws in case

you choose to remove the auxiliary power supply in the future.

Figure 2 Removing the Blank Plate.

2. Orient the AT-PWR4 power supply housing as shown in Figure 3. Install

the power supply in the chassis bay by sliding the housing loosely into the

bay. Seat the AT-PWR4’s power connector firmly in the mating connector

on the backplane inside the rackmount chassis. Tighten the two thumb

screws to complete the installation.

the following procedure:

1. Connect the power cord to the power supply, as shown in Figure 4.

Figure 4 Connecting the AC Power Connector to Switch

2. Connect the power cord to an appropriate power outlet.

3. The power supply is self-adjusting for AC input power between 120 Volts and 240

Volts.

4. Verify that the POWER (PWR A or PWR B) LED is green. If the LED is OFF, refer

to the following “Testing and Troubleshooting the Installation” section.

The switch is ready for network operations.

Testing and Troubleshooting the Installation

Follow the guidelines in this section for testing and troubleshooting the

installation in the event a problem occurs.

1. Verify that the

POWER (PWR A or PWR B) LED is green. If one of the LEDs

is OFF, do the following:

❑ Check to be sure that the power supply is securely connected to the

power outlet.

❑ Check to be sure that the power supply is securely seated in the

chassis.

2. Check to be sure that the fans for both power supplies are operating. If a

fan is not operating, it is likely that the power supply has failed.

If you are still experiencing problems after testing and troubleshooting the

installation, contact Allied Telesis Technical Support at
