3. Check AC operation of the 1145B2 Power Supply by monitoring the LEDs:

PASS: Green and yellow LEDs at the front of the unit should be lit together. Green means 
the power supply is providing power. Yellow means the battery is being charged. After the 
battery reaches full charge (maximum of 20 hours), the yellow LED should go out.

FAIL: If either green or yellow LED is not lit after powering up, check the connections. Test 
the AC outlet. If power is available and the AC power cord and connections are good, 
replace the power unit.

4. Disconnect the AC plug on the power supply, this activates the DC supply.

5. Check DC (battery back-up) operation of the 1145B2 Power Supply by monitoring the LEDs:

PASS: The red and green LEDs should be lit together. Red means the power supply is on 
battery back-up.

FAIL: If either green or red LED is not lit after disconnecting AC power, check the 
connections. If the connections are good, replace the power unit or batteries.

6. Reconnect AC power to the power supply.

Wire endpoints to the 1146B2 while power from the 1145B2 is on. A red LED lights if its 
associated circuit is connected to shorted wiring or to a shorted telephone.

To wire the 1146B2 Power Distribution Unit:

1. Install cross-connect jumpers to wire from the unit (the label shows polarity) to Pins 7 and 8 

of the appropriate information outlet. Route the wires through the clip provided on the unit. If 
a red LED is on, see 

on page 106. See 

2. Mark lead destinations on the label next to each connector. Also mark the Unit Number and 

Connectivity information on the label.
