Power Protection

Runtimes

The UPS will provide battery backup to allow for a graceful shutdown in the event of a power failure. Typical runtime on the
APC SL20KFB2 Silcon 3 Phase UPS varies with the kW rating and the load. The APC SL20KFB2 UPS provides a typical
runtime of 36.7 minutes at half load and 10.7 at full load. If additional run time is needed please contact your APC
representative.

Power Conditioning

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.

Input Power

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.

Guidelines

Guidelines

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.

Superdome

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 (such as HP High Availability Disk Array Model 20) 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.

Integration/Installation

The APC SL20KFB2 includes both field integration start up service and next day on site service for one year provide by APC.
