Glossary of SymmetraTM Terms

Extended Run Battery Frame - An accessory that increases the battery capacity of a system. Multiple Extended Run frames can be connected to a single SymmetraTM to significantly increase run time.

Hot-Swappable- Modules are “hot-swappable” when they can be replaced safely while the load equipment is still powered and the SymmetraTM is fully functional.

N+1 - Refers to the level of power module redundancy. “N” represents the number of power modules required to power the load, and “+1, +2, etc.” represents the number of extra power modules that are installed. For example, a 7.3 kVA load requires two power modules for adequate protection. If the SymmetraTM is configured with only two modules, it has an “N+0” level of redundancy, or no redundancy. If the system is configured with three power modules, it has an “N+1” redundancy. Depending on the the load requirements, SymmetraTM can be configured with 2, 3 or even 4 extra power modules, giving it an N+2, N+3, or N+4 level of redundancy.

Redundancy - Refers specifically to power modules. If at least one “extra” power module is installed, the system can sustain a fault condition and still provide protection to the load equipment. To be fully redundant, the system should be configured with at least one redundant power module, and a minimum of two battery modules. (When two or more battery modules are present, one of them can fail and the system will still have a battery power source. The total number of battery modules determines the length of on-battery run time.)

Scalability - The modular architecture allows the user to increase power capacity as load requirements in- crease. Scalability is limited by the size of the frame, and the number of available power module bays.

SmartSlotTM Accessories - SmartSlotTM bays at the rear of the frame accommodate up to four accessory cards. Before installing any SmartSlotTM accessory, ensure it is a compatible “SymmetraTM OK” model.

νShare-UPSTM- Provides automatic shutdown of up to two additional servers.

νPowerNetTM SNMP - Provides network UPS management.

νMeasure-UPSTMII - Provides environmental information such as ambient temperature and humidity.

νCall-UPSTM- Works with an external modem to provide out-of-band UPS management.

System Capacity - The maximum output power that a SymmetraTM system can deliver. System capacity is limited by the lesser of the frame size, or the capacity of the installed power modules.

νA Mini Frame (8kVA) with one power module installed (4kVA) has a system capacity of 4kVA.

νA Master Frame (16kVA) with five power modules (20kVA) has a system capacity of 16kVA.
