Voltage Check
This section provides voltage check information for use on the customer site. The emphasis focuses on
measuring the voltages at the power cord plug end specified as an IEC 320 C19 type plug. This end plugs
directly into the back of the HP 9000 rp7420 Server chassis.
NOTE These procedures must be performed for each power cord that will be plugged directly into the
back of the HP 9000 rp7420 Server. If the expected results from this procedure are not
observed during the voltage check, see the next section titled “Voltage Check (Additional
Procedure).”
Preface
The HP 9000 rp7420 Server requires a minimum of 2 power cords. To enable full power redundancy, 4 power
cords may be used. When using 4 power cords, dual power sources may be used to provide additional power
source protection.
Power cords are designated and labled A0, A1, B0 and B1. Cords A0 & B0 should be energized from the same
power source and cords A1 & B1 should be energized from a second, independently qualified power source.
The cord labeling corresponds to the labeling at the servers power receptacles.
