design and installation of a power distribution system for an hp rp7405/rp7410 server requires specialized skills. Those practices, produces the most trouble-free operation. The electrical factors discussed in this section are: A detailed discussion of power distribution system design and - HP Rp7410 | Site Preparation Guide, Second Edition - hp rp7405/rp7410 Servers - Page 31
Electrical Load Requirements (Circuit Breaker Sizing) It is always a good idea to derate power distribution systems for one or more of the following reasons: • To avoid nuisance tripping from load shifts or power transients, circuit protection devices should never be run above 80% of their root-mean - HP Rp7410 | Site Preparation Guide, Second Edition - hp rp7405/rp7410 Servers - Page 32
-Isolates server power distribution system from other circuits in the facility. • Missing-phase and low-voltage detectors-Shuts equipment down automatically when a severe power disruption occurs. For peripheral equipment, these devices are recommended but optional. • Online uninterruptible power - HP Rp7410 | Site Preparation Guide, Second Edition - hp rp7405/rp7410 Servers - Page 33
Use copper conductors instead of aluminum, as aluminum's coefficient of expansion differs significantly from that of other metals used in power hardware. Because of this difference, aluminum conductors can cause connector hardware to work loose, overheat, and fail.
