Avaya 03-300430 User Manual

The TN2312BP and the 655A power supply provide the following information to the G650:

●

- Inlet temperature - Inlet temperature of the G650 (sensor is in the 655A power supply)

- Exhaust temperature - G650 carrier exhaust air sensor

- Hot Spot temperature status- 655A power supply sensor

- Voltage

- +5VDC

- -5VDC

- -48VDC

- Fan Control - The speed at which the fans are operating:

- Undr indicates that the fan voltage is under 12VDC.

- Mid (normal) indicates that the fan voltage is +12VDC.

- High indicates that the fan voltage is +14VDC.

- Over indicates that the fan voltage is above 14 to 15VDC.

- Fan Alarm - Detection of a blocked or failed fan

- Ring Status - OK, overload, shorted, or failed 

- Ring Control - Active, standby, disabled, off (shorted or failed)

- Ringer Setting - 20Hz, 25Hz, or other

- Ring Detection - Reports if the power supply detects ring on the backplane ring leads 

- Input Power - Indicates the type of power present and in use, AC or DC

●

The external device alarm detection uses two external leads. External devices such as an 
uninterruptible power supply (UPS) or voice messaging system can use these leads to 
generate alarms using the Avaya Communication Manager alarm reporting capability. 
Ground potential on either of these leads results in an alarm being generated. You can 
administer the alarm level (major, minor, or warning), product ID, alternate name, and alarm 
description for each lead. 

●

Emergency transfer control provides -48VDC to operate an external emergency transfer 
panel. The Communication Manager controls the state of the emergency transfer. (Note 
that, in the past, hardware boards or alarm panels provided a three-position physical switch 
to control emergency transfer.) An emergency transfer status red LED shows when 
emergency transfer is active.
