Each of the 1600-W power supplies has a single AC input. The power supply provides 12-VDC output
with a standby voltage of 12 VDC. A PTX1000 provides for twice the number of power supplies needed
to power all of the components in the device, which is known as 2N redundancy. When the PTX1000 has
all four power supplies installed and connected to power, the router has full power redundancy. If a power
supply fails or is removed, another power supply balances the electrical load without interruption.
