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.
