Notes:
1. This table represents general guidelines for selecting the appropriate UPS based on minimum and typical
runtime estimates. A ‘maximum configuration’ load will result in ‘minimum’ UPS runtime. ‘Typical’
loads are based on a production system running at approximately 70% of maximum capacity (based on
the power delivered to the device from the power source, i.e., 70% of the value provided as a maximum
equals the rating of the power supply). The ‘typical’ loads represent a more likely configuration;
therefore, they provide a more likely estimate of runtime. The values listed as typical generally are equal
to the rating of the power supply. Since power supplies operate at 70% of load, the system power
supplies are actually operating at 70% of the values listed, though the power required from the source is
what is listed. Customer environments are unique and are unlikely to be precisely represented by any of
the specific entries in the table.
2. Power-Factor Corrected (PFC) power supply.
3. Use with IBM UPS7500X or UPS10000X only.
