Power Configuration Table
Second power regulator may be needed to supply additional 48V power to the system.
Mixing of three-phase and single-phase power regulators in system configuration is not allowed.
Use chart to determine need for second power regulator.
If EPU is greater than 80, order second power regulator (three-phase regulator
H7263-AC/AD) or H7263-AA/AB if
BBU is required).
EPU must not exceed 180.

Note: Depending on configuration, system offers integral UPS capability that supports all in-cabinet components for at
least 11 minutes. If UPS support is required for external devices, e.g., console terminals, terminal servers, printers,
and modems, a universal UPS can be ordered separately.
