Fixes for the most common Cisco Codec Pro G2 problems, from the quickest checks to when to contact Cisco. Start at the top: most issues are a setting, a cable or firmware.
What the Codec Pro G2 has
Check the problem against what this model actually has:
- Network: 1G LAN, 10G peripheral port, 8x PoE/PoE+/PoE++ (120 W), Wi-Fi 6E (radio versions)
- Power: Up to 270 W
- In the box: codec Pro G2, mounting brackets, antenna (radio version) and power cord
Quick checks
- Restart the device: unplug power for 30 seconds, then reconnect.
- Reconnect the cables, using the ones that came in the box.
- Check that the Codec Pro G2 is selected as the device in Teams, Zoom or Meet.
- Update the firmware. How
No picture on the displays or the room app won't start
- Check each display cable and the display inputs.
- Restart the unit from the touch controller, or by removing power for 30 seconds.
- Check the room account can still sign in (expired passwords and licenses are common causes).
- Apply pending OS and room software updates.
Camera or audio missing in the room app
- Reseat the USB cables at the unit; use the ports the manufacturer recommends for cameras and audio.
- Check the default camera, microphone and speaker in the room app's device settings.
- Restart the unit.
Keeps disconnecting or drops out
- Use the original cable and a direct port on the computer; long or cheap USB extensions cause dropouts.
- Turn off USB power saving on the computer (Windows: Device Manager → USB Root Hub → Power Management).
- Use wired Ethernet rather than Wi-Fi, and check the switch port for errors.
- Update firmware and the meeting app.
Won't turn on or status light is red/blinking
- Check the power adapter is the original one and firmly connected, and try another outlet.
- Unplug for 30 seconds and power it back on.
- Check the status light meaning in the user guide; a blinking light during startup or updates is often normal.
- If it never finishes starting, contact the manufacturer's support for a recovery.
