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 C4500 1400 W DC Triple Input SP Power Supply requires a minimum draw
from the system that it is installed in.
