power at 110 VAC. The Ethernet Routing Switch 8300 supports N+1 power redundancy. The
2+1 configuration (two nonredundant power supplies and one redundant power supply)
provides up to 1600 watts PoE power with 220VAC.
Caution:
Risk of equipment failure
When installing and running PoE modules, the 8306 or 8310 chassis cannot contain different
power supply types: all power supplies on the chassis must be of the same type (either
Ethernet Routing Switch 8301 or 8302 AC power supplies). Otherwise, all PoE 8348TX-
PWR or 8348GTX-PWR modules lose PoE power when the chassis detects the mixed
power supplies.
When you connect the 8301AC power supply to a 100–110 VAC nominal input voltage source,
one power supply draws a maximum of 20 Amps and delivers 1140 watts of output power.
Each Ethernet Routing Switch 8301 power supply provides 400 watts of PoE power at 100–
110 VAC.
When you connect the 8301AC power supply to a 200–240 VAC nominal input voltage source,
one power supply draws a maximum of 15 Amps and delivers 1770 watts of output power.
Each Ethernet Routing Switch 8301 power supply provides 800 watts of PoE power at 200–
240 VAC.
If you install a redundant power supply, power available for PoE is always determined on a N
+1 redundancy. If you install two power supplies in the chassis, PoE power allocation is
equivalent to one power supply. If you install three power supplies in the chassis, PoE power
allocation is equivalent to two power supplies.
In an Ethernet Routing Switch 8300, the total power available for PoE is always determined
on the N+1 redundancy policy.
The following table lists the redundancy policy for Ethernet Routing Switch 8300.
