24 Appendix Electrical specifications for the AC power supply
Note the following information:
• The maximum steady-state output power is limited to a total of 1140 W
for any combination of output voltages/currents at low-line 100-120 VAC
nominal input voltage conditions.
• The maximum steady-state output power is limited to a total of 690 W
for any combination of output voltages/currents, excluding the 50 VDC
source at low-line 100-120VAC nominal input voltage conditions. This
limitation is required to ensure that there is sufficient PoE power or 450
W total at this input voltage condition.
• The maximum steady-state output power is limited to a total of 870W
for any combination of output voltages/currents, excluding the 50 VDC
source at high-line 200-240VAC nominal input voltage conditions. This
limitation is required to ensure maximum PoE power or 900 W total for
the 50 VDC source at this input voltage condition.
• To obtain the full output power rating of 1770 W, you must connect the
power supply to a nominal (200-240VAC) input voltage source.
The following table list the power specifications for the Ethernet Routing
Switch 8302AC power supply.
