Specify Power Connections
The HP rp7400 power system is a 200/208/230/240 VAC product requiring a dedicated 20A branch circuit. The
power system is comprised of two or three 10A, 1163W n+1 hot-swappable system power supplies, depending
on how the system is configured. The total continuously available power to the SPU is 2 x 1163W or 2325W.
HP does not support plugging HP rp7400 power supplies into wall or floor sockets. The power cords
provided for the power supply is plugged directly into a UPS or a power distribution unit (PDU) using a
jumper cord (HP part number 8120-1860). Customers wishing to connect directly to wall or floor sockets must
provide their own power cord solution.
NOTE The acronym PDU (power distribution unit) in this document refers to the power strips
attached to the HP rp7400 cabinet.
CAUTION HP does not recommend and does not support the use of “ferro-active” or “ferro-resonant”
power correction in conjunction with the rp7400 server. These type of line conditioners
represent an older technology that is not compatible with the most recent designs in active PFC
power supplies such as those in the HP rp7400 servers. “Ferro-active” or “ferro-resonant” line
conditioners may cause an increase in total harmonic distortion and may produce significant
and unpredictable voltage regulation anomalies.
Modular PDUs
Two modular PDUs are available for use with the rp7400 product:
• 20A modular PDU, HP product number E7674A. This PDU has seven C13 outlets and one C19 outlet.
Note that if this PDU is used to power the rp7400 SPU, any other peripherals must have their power
supplied by additional PDUs in the cabinet. The PDU power cord (HP part number 8120-6903) has an
L6-20P plug which must be plugged into an L6-20R wall or floor receptacle.
