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.

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.

HP does not support plugging HP rp7400 power supplies into
wall or floor sockets
. The power cords provided for the power supply is

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

“Ferro-active” or “ferro-resonant” line conditioners may
cause an increase in total harmonic distortion and may
produce significant and unpredictable voltage regulation
anomalies.
