your configuration. For the 8005DI DC power supply specifications, see 8005DI DC
power supply specifications on page 29.
3. Consider your redundant power supply needs. If one power supply satisfies your
system power consumption needs, a second power supply provides redundancy. If
two power supplies satisfy your system power consumption needs, a third power
supply provides redundancy.
AC power supply specifications
This section describes the power specifications for the Ethernet Routing Switch 8301AC and
8302AC power supplies.

8301AC power supply specifications
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 100-120 VAC nominal input
voltage conditions. This limitation is required to ensure that you have sufficient PoE power or
450 W total at this input voltage condition.
The maximum steady-state output power is limited to a total of 870 W for any combination of
output voltages or currents, excluding the 50 VDC source at high-line 200-240 VAC 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 (200-240 VAC) input voltage source.
The following table specifies individual AC input and DC output power ratings for each 8301AC
power supply.
