Brand:

Affected Products:

  • CE-IO4
  • CE-IRS4
  • CE-REL8
  • CE-COM2

Summary:

The CE Series IO Extender may become unreachable on the network after a hard power cycle when changing its IP configuration from DHCP to Static or from Static to DHCP.


Troubleshooting:

When changing the IP configuration, the device may not commit the new network settings if power is removed before a reboot is performed through the Web UI.

Always reboot the device through the Web Interface immediately after saving network settings by following the process below:

  1. Configure the required IP settings in the Web UI and save the changes.
  2. IMMEDIATELY use the "Reboot" button in the Web Interface.
  3. Wait for the device to complete the reboot process.
  4. Verify that the new IP configuration is working as expected.

Only disconnect power or move the device after the reboot has completed.

 

Critical Warning

Never unplug the cable or remove power before rebooting the device via the Web Interface.

This issue affects all CE-Series models (PoE dependent).

Consequences of skipping the reboot:

  • The unit IP becomes 0.0.0.0.
  • The device is offline.
