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
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
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.
Rule Description Rule Description Rule Description Rule Description
1 Every Superdome complex requires connectivity to a Support Management Station (SMS). The PC-based SMS also
serves as the system console.
2 Every cell in a Superdome complex must be assigned to a valid physical location.
3 All CPUs in a cell are the same type, same Front Side Bus (FSB) frequency, and same core frequency.
4 Configurations with 8, 16 and 32 DIMM slots are recommended (i.e. are fully qualified and offer the best
bandwidth performance.)
5 Configurations with 4 and 24 DIMM slots are supported (i.e. are fully qualified, but don't necessarily offer the
best bandwidth performance).
6 DIMMs can be deallocated in 2 DIMM increments (to support HA).
7 Mixed DIMM sizes within a cell board are supported, but only in separate Mbat interleaving groups.
8 System orders from the factory provide mixed DIMM sizes in recommended configurations only.
9 For system orders from the factory, the same memory configuration must be used for all cells within a partition.
DIMMs in the same rank must have SDRAMs with the same number of banks and row and column bits.
Size of memory within an interleave group must be power of 2.
DIMMs within the same interleave group must be same size and have same number of banks, row bits, and
column bits.
There are currently no restrictions on mixing DIMMs (of the same type) with different vendor SDRAMs.
