1. AC Power Connectors — Connect both AC power connectors to an Uninterruptible Power Supply
(UPS) to provide redundant power for your px12-400r. The AC power supply will automatically switch to
the correct voltage for your region.
2. Power Supply — The px12-400r has redundant hot-swappable power supplies. If one power supply
fails, the other power supply will immediately take over. For maximum time-up, a failed power supply can
be replaced while the px12-400r is running.
3. System ID LED — Flashes blue when the Blink Lights feature is enabled in the px12-400r Management
Console. This light is used to identify a specific px12-400r in installations with multiple devices.
4. Reset Button — Hold the Reset button for four seconds to reset security and network settings. This
allows you to regain access if network settings are incorrect or you've forgotten your password.
The reset button does not initiate a full factory reset. To perform a full factory reset, select Factory
Reset from the System page in the px12-400r Management Console.
5. USB 2.0 connectors — Supports devices such as USB storage devices and printers.
6. Gigabit Ethernet Ports — High-speed Ethernet connectors that automatically detect your network
speed (10/100/1000Base-T).
