1.
Take the AC voltage down to the lowest scale on the volt meter.
2.
Insert the probe into the ground pin for B0.
3.
Insert the other probe into the ground pin for B1.
4.
Verify that the measurement is between 0-5 V AC.
If the measurement is 5 V or greater, escalate the situation. Do not attempt to plug the power
cord into the server cabinet.
3.
Measure the voltage between A0 and B0 as follows:
1.
Take the AC voltage down to the lowest scale on the volt meter.
2.
Insert the probe into the ground pin for A0.
3.
Insert the other probe into the ground pin for B0.
4.
Verify that the measurement is between 0-5 V AC.
If the measurement is 5 V or greater, escalate the situation. Do not attempt to plug the power
cord into the server cabinet.
4.
Measure the voltage between A1 and B1 as follows:

4.
Verify that the measurement is between 0-5 V AC.
If the measurement is 5 V or greater, escalate the situation. Do not attempt to plug the power
cord into the server cabinet.
Voltage Check (Additional Procedure)
The voltage check ensures that all phases (and neutral, for international systems) are connected
correctly to the cabinet and that the AC input voltage is within limits.
Perform this procedure if the previous voltage check procedure did not yield the expected results.
NOTE:
If you use an uninterrupted power supply (UPS), refer to applicable UPS documentation
for information on connecting the server and checking the UPS output voltage. UPS user
documentation is shipped with the UPS. Documentation is also available at:
