Connect Router AIR-CAP2602I-N-K9 by console port to USB-C in terminal

[kavinesh]

• What have I tried?

Once I connected the console cable to the router and my system, I checked that the USB port was available in my system and accessible.

$ ls -l /dev/*USB*  
/dev/ttyUSB0
$ dmesg 
...

• What Goes Wrong?

While running the below command, the terminal goes blank

$ screen /dev/ttyUSB0 9600

• What do I need to achieve?

I need to access the router in the terminal.

if the drivers installed correctly and Cable is good.

I can see the drivers installed ok - worth checking :

lsusb | grep -i --color PL2303

ls -l /dev/ttyUSB*

you can try using sudo :

sudo screen /dev/ttyUSB0

Thanks for the response @balaji.bandi,

I even tried it with sudo as well as the direct root user. But still, I got the blank terminal.

Hello,

with the USB port connected, try a factory default reset and check what appears on your terminal. I think this is the procedure:

The Cisco AIR-CAP2602I-N-K9 access point can be restored to its factory default settings by following these steps:

1. **Power Off the Access Point**: Disconnect the power source from the access point.

2. **Press and Hold Reset Button**: Locate the reset button on the access point. It's usually recessed and may require a small tool like a paperclip to press. Press and hold the reset button.

3. **Power On the Access Point**: While continuing to hold the reset button, reconnect the power source to the access point.

4. **Hold Reset Button**: Keep holding the reset button until the LED lights on the access point start flashing. This usually takes about 10 to 30 seconds.

5. **Release Reset Button**: Once the LED lights start flashing, release the reset button.

6. **Wait for Reset**: Allow the access point to reboot and reset to its factory default settings. This process may take a few minutes.

After the access point has completed the reset process, it will be restored to its factory default settings, including the default configuration and default credentials (if any). You can then access the access point using the default settings, typically via a web interface or through the console port using a terminal emulator.

Remember that performing a factory reset will erase any custom configurations and settings on the access point, so make sure to back up any important configurations before proceeding.

Thanks for the response @Georg Pauwen,

In my case am not aware of the access point of the router which was a dynamic setup, and also we are not able to do a factory reset as the factory reset button is not working (tried multiple times but the router is not resetting, seems reset button is not working) followed same as you have suggested to do a factory reset. For this reason, am looking to connect the router with the terminal.
