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 1-9 provides output information for these modes, given two supplies working in combined mode.
Table 1-10 provides 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 1-11 shows the minimum draw for the possible modes.
