The HP rp54xx power system is comprised of one, two or three autoranging, 12A/10A/5A, 930W hot-swappable system power supplies, depending on how the system is configured. The maximum power needed by fully-configured server is 1200W. Each power supply requires a dedicated 20A branch circuit.
At the server level, enhanced power availability is achieved through the n+1 hot-swappable power supplies. One power supply is required for a minimally configured rp54xx system operation and in order to allow the system to boot. If a second power supply is present, one of the two power supplies can fail without the system shutting down. Similarly, two power supplies are required for a more heavily-configured rp54xx server. If a third power supply is present, one of the two power supplies can fail without the system shutting down. If a third (redundant) power supply is present, all three power supplies become hot-swappable. Any one of the power supplies can fail without affecting system performance, and can be replaced while the system is on-line. Single point of failure is reduced to the local wall circuit or PowerTrust UPS to which the power supply power cords are connected. Power protection is provided through the use of HP PowerTrust UPSs (Uninterruptible Power Supplies). The only supported models for rp54xx systems are the 3.0kVA and 5.5kVA models. Recommendations for other manufacturers and models are not yet determined. HP rp54xx server power supplies may be plugged directly into the customer's site UPS. However, customers are advised against plugging the power supply into an HP PowerTrust UPS and then connecting that UPS to the site UPS.
Three modular PDUs are available for use with the rp54xx product:
