Required PDU configuration

  • The device must be configured before connecting the WNC.

    • This is accomplished via the web console or the serial console. please follow the instructions in the PDU user guide.

    • Alternatively, a factory reset can be performed by using the reset button inside an unlabeled hole next to the LED displays or network port. Use a paperclip or other tool to press and hold the button for between 10 and 15 seconds. The reset process will take about 3-1/2 minutes to complete. This process will not affect outlet on/off status. Please refer to the ServerTech FAQ documentation for more details.

  • If the device cannot be factory reset, then the device must be configured with static IP networking settings for the ethernet port.
    IP address:
    Subnet Mask:
    Default gateway:

This can be accomplished in a few ways.

  • If the device is currently connected to and accessible via an existing IP network, follow the instructions in the user manual.

  • If the device is not already connected to an IP network, follow the instructions in the manufacturer's installation guide, quick start guide, or user manual to configure the device with a static IP address. Options here may include local serial console connection.


WNC Connections

1.  Connect one end of an ethernet cable to the NET port on the PDU control panel.
