Avaya 03-300430 User Manual

The POW-SUP maintenance object notes the presence of each power supply and the voltage of 
each power supply in the G650. 
This MO:

●

Verifies that a power supply that is administered is physically present

●

Verifies that each output voltage (+5V, -5V, and -48V for the power supplies and +12V for 
the fan) is within tolerance

●

Is used with the recycle carrier command to momentarily turn off and on the power to 

a specified power supply or to a specified carrier 

●

Is used to turn off output voltages from one power supply to verify that the other supply can 
support the entire load of the G650 (This is used only when a G650 has redundant power 
supplies.)

There is one instance of this MO for each 655A power supply equipped in a G650 stack. Refer 
to 

on page 1959 for further 

information.
If you have redundant power supplies, and both are operating, you can unplug one power 
supply and leave it unplugged for ten minutes without causing an alarm. If the remaining 
operating power supply has an alarm, the system does not wait ten minutes to generate an 
alarm. It generates an alarm immediately. If the power supply is unplugged for more than ten 
minutes, the system generates a warning alarm with an Error Code 23. If you need the power 
supply to be unplugged for more than ten minutes, and you do not want the system to generate 
an alarm, use the change circuit pack command to un-administer the power supply. 

1. This is a minor alarm if there is a redundant power supply, and a major alarm if there is only one 

power supply.
