Configuration
The APC SL20KFB2 provides unparalleled power conditioning with its Delta-Conversion on- line double conversion
technology. This is especially helpful in regions were power is unstable.

The APC SL20KFB2 will provide battery backup to allow for continuous power to the connected equipment in the event of a
brief interruption in the input power to the UPS. Transaction activity will continue during brief power outage periods as long
as qualified UPS units are used to provide backup power to the SPU, the Expansion Modules, and all disk and disk array
products.

In general, the sum of the "Watt rating for UPS sizing" for all of the connected equipment should not exceed the watt rating
of the UPS from which they all draw power. In previous configuration guides, this variable was called the "VA rating for UPS
sizing." With Unity Power Factor, the Watt rating was the same as the kVA rating, so it didn't matter which one we used. VA is
calculated by multiplying the voltage times the current. Watts, which is a measurement of true power, may be less than VA if
the current and voltage are not in phase. APC SL20KFB2 has Unity Power Factory correction, so the kW rating equals the
kVA rating. Be sure to add in the needs for the other peripherals and connected equipment. When sizing the UPS, allow for
future growth as well. If the configuration guide or data sheet of the equipment you want to protect gives a VA rating, use
this as the watt rating. If the UPS does not provide enough power for the additional devices such as system console and mass
storage devices, additional UPSs may be required.

The only qualified UPS available for use with Superdome is the APC SL20KFB2 Silcon 3 Phase 20-kW UPS.
The APC SL20KFB2 can provide power protection for the SPU and peripherals. If the system console and primary mass
storage devices also require power protection (which is highly recommended) they may require one or more additional UPSs
depending on the total Watts. Make sure that the total watts do not exceed the UPS's voltage rating.

Some customers may experience chronic "brown-out" situations or have power sources that are consistently at the lower
spectrum of the standard voltage range. For example, the AC power may come in consistently at
92 VAC in a 110 VAC area. Heavy-load electrical equipment or power rationing are some of the reasons these situations
arise. The APC SL20KFB2 units are designed to kick in before the AC power drops below the operating range of the HP
Superdome Enterprise Server. Therefore, these UPS units may run on battery frequently if the AC power source consistently dips
below the threshold voltage. This may result in frequent
system shutdowns and will eventually wear out the battery. Although the on-line units can compensate for the AC power
shortfall, the battery life may be shortened. The best solution is to use a good quality boost transformer to "correct" the power
source before it enters the UPS unit.
