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.
Ordering Guidelines Ordering Guidelines Ordering Guidelines Ordering Guidelines
The APC SL20KFB2 Silcon 3-phase UPS units may be ordered as part of a new Superdome system
order or as a field upgrade to an existing system.
For new systems order please contact Ron Seredian at APC by e-mail at
during the Superdome pre-consulting phase. APC will coordinate with HP to ensure the UPS is
installed to meet the Superdome installation schedule.
For field upgrades please contact Ron Seredian at APC by e-mail at
you determine a customer is in need and/or interested in power protection for Superdome. APC
will coordinate with the customer to ensure the UPS is installed to meet their requirements.
Numerous options can be ordered to compliment APC SL20KFB2 Silcon 3-phase UPS units. Your
APC consultant can review these option with you are you can visit the APC website at

Superdome servers, by default, provide an additional power supply for N+1 protection. As a result,
Superdome servers will continue to operate in the event of a single power supply failure. The failed
power supply can be replaced without taking the system down.
When configuring Superdome systems that consist of more then one cabinet and include I/O expansion
cabinets, certain guidelines must be followed, specifically the I/O interface cabling between the
Superdome cabinet and the I/O expansion cabinet can only cross one additional cabinet due to cable
length restrictions.
