Checking Voltage
The voltage check ensures that all phases (and neutral, for international systems) are wired correctly
for the cabinet and that the AC input voltage is within specified limits.
NOTE:
If you use a UPS, see applicable UPS documentation for information to connect the server
and to check the UPS output voltage. UPS User Manual documentation is shipped with the UPS
and is available at www.hp.com/go/bizsupport.
