Set up Conguration Environment via Console Port
Step 1: Connect the serial port of a PC (or a terminal) to the console port of the switch with the
console cable.
Step 2: Turn on the PuTTY. Choose the“Serial” as the Protocol.
Step 3: In the Port item, please choose specied COM port that the PC is using.
Step 4: Set the baud rate to 115200, data bit to 8, parity check to none, stop bit to 1, ow control to
none.
Step 5: Enter the default login information:
Username: cumulus
Password: CumulusLinux!
Step 6: Use the corresponding commands to congure the switch or to monitor the running state.
Conguring the Switch (Only for Cumulus Linux Switch)
Install Cumulus Linux license key
There are three ways to install the license onto the switch:
Installing Cumulus® Linux® License Over Switches
Copy and paste the license key into the cl-license command:
cumulus@switch:~$ sudo cl-license -i
<paste license key>
^+d
Copy the license from a local server. Create a text le with the license and copy it to a server
accessible from the switch. On the switch, use the following command to transfer the le directly
on the switch, then install the license le:
cumulus@switch:~$ scp user@my_server:/home/user/my_license_file. txt .
cumulus@switch:~$ sudo cl-license -i my_license_file.txt
Copy the le to an HTTP server (not HTTPS), then reference the URL when you run cl-license:
cumulus@switch:~$ sudo cl-license -i <URL>
CAUTION: It is not necessary to reboot the switch to activate the switch ports. After you
install the license, restart the switchd service. All front panel ports become active and
show up as swp1, swp2, and so on.
cumulus@switch:~$ sudo systemctl restart switchd.service

Troubleshooting for Terminal No-show
After power-on, if the conguration terminal shows nothing, you can rstly check the following:
Troubleshooting for Terminal Show Error Codes
If the conguration terminal shows error codes, it is likely that the terminal (such as the HyperTerminal)
are set incorrectly. Please conrm the parameters of the terminal.
Troubleshooting
According to the power indicator on the front panel, the switches can be used to determine whether
the power system of the switch is faulty. If the power supply system is working normally, the power
indicator should remain lit; If the power indicator is unlit, the power supply system is not working.
Please check the following:
Power System Troubleshooting
After the switch is powered on, if the system is normal, the startup information will be displayed on
the conguration terminal. If there is something wrong with the conguration system, the
conguration terminal may not display or display error codes.
Conguration System Troubleshooting
Whether the switch power cable is connected correctly.
Whether the power supply of the switch matches the required power supply.
If there is no problem with the above, it is very likely that there is a problem with the conguration
cable or the terminal (such as the HyperTerminal) parameters were set incorrectly.
Whether the power supply is normal.
Whether the console cable is properly connected.
