Front panel power connector A two-pin male Molex connector is located in the
lower right corner of the power supply front panel. The
connector provides 42 VDC at a maximum of 17 A.
This connector provides power to the
WS-6509-NEB-UPGRD kit fan assembly through a
power harness also provided in the kit. A hinged
protective flap secured by a captive screw covers the
connector when it is not in use.
Output holdup time 20 ms minimum
Heat dissipation 12,046 BTU/hour (approx.)
Front panel LEDs
