X A + 1.1 A
Input current from a DC source other than –48 VDC (based on maximum configuration;
applies to DC power supply only):
(–54 VDC input) x (input current X) = (–48 VDC input) x (input current Y)
54 x X = 48 x 57.9 A
X = 48 x 57.9 A/54 = 51.5 A
Example of calculating system thermal output for a DC-powered router:
Watts DC/0.293 = BTU/hr
3,586/0.293 = 12,239 BTU/hr
Example of calculating system thermal output for an AC-powered router:
Watts DC/85% AC PEM efficiency/0.293 = BTU/hr
3,586/0.85/0.293 = 14,398 BTU/hr
