7.6 What’s Next?
After connecting a terminal client, it may not immediately see any output. This could be because the device has already
finished booting or it may be that the device is waiting for some other input.
If the device does not yet have power applied, plug it in and monitor the terminal output.
If the device is already powered on, try pressing Space. If there is still no output, press Enter. If the device was
booted, it may redisplay the console menu or login prompt, or produce other output indicating its status.
From the console, a variety of things are possible, such as changing interface addresses. There is a full explanation of
every console menu option in the pfSense software documentation.
7.7 Troubleshooting
7.7.1 Serial Device Missing
With a USB serial console there are a few reasons why the serial port may not be present in the client operating system,
including:
No Power Some models require power before the client can connect to the USB serial console.
USB Cable Not Plugged In For USB consoles, the USB cable may not be fully engaged on both ends. Gently, but
firmly, ensure the cable has a good connection on both sides.
Bad USB Cable Some USB cables are not suitable for use as data cables. For example, some cables are only capable
of delivering power for charging devices and not acting as data cables. Others may be of low quality or have
poor or worn connectors.
The ideal cable to use is the one that came with the device. Failing that, ensure the cable is of the correct type
and specifications, and try multiple cables.
Wrong Device In some cases there may be multiple serial devices available. Ensure the one used by the serial client
is the correct one. Some devices expose multiple ports, so using the incorrect port may lead to no output or
unexpected output.
Hardware Failure There could be a hardware failure preventing the serial console from working. Contact Netgate
TAC for assistance.
