Chapter 1 Product Overview

Power Supplies

The maximum total input current is 42.5A and the maximum ambient temperature is 55 C. To determine total maximum input power to a supply, add up the active individual module input power ratings. Table 1-9provides output information for these modes, given two supplies working in combined mode. Table 1-10provides output information for these modes, given two supplies working in redundant mode.

Note In a redundant configuration with all inputs supplied, there must be a 100 W minimum system load or the OUTPUT FAIL LED shows a false failure.

The 1400 W DC Triple Input SP Power Supply requires a minimum draw from the system that it is installed in. Table 1-11shows the minimum draw for the possible modes.
