2.2. Flashing Routing Firmware¶

This is a guide to install new firmware with CLI, confirm image, switch active boot image, turn on all ports, and finally don’t forget to “write memory”, this will set the configuration file.

Requirements:

Running TFTP server;
Downloaded firmware for Quanta LB4m - firmware image lb4m.5.13.12.14.bin (You can use this direct download link;
Client for serial port connection with the switch (for example PuTTY).

Below it will be use an address 192.168.50.2 for access to the TFTP server. The firmware name in this example is firmware.bin. Use appropriate settings for your specific case.

The first step is to connect the Serial/COM port of the computer used for the flashing process to the Quanta LB4 Swtich console port. Use a console cable (roll over cable with RJ45-DB9 converter) for this purpose.

Using PuTTY terminal emulator go to the category Connection and expand the Serial options. Enter the port number inside “Serial line to connect to:” text box - COM1 for example. The port number may be different in your computer. Enter the correct port number when you connect from your computer. Configure the serial line with the following values Speed (baud): 115200, Data bits: 8, Stop bits: 1, Parity: none, Flow control: none.

Click Session and click Serial radio button. Verify whether you can see the port number and the baud rate (115200) you had selected before. Click Open to connect to Quanta LB4 Swtich. Use admin as a login name, the default password is blank. Hit enter again and you should get the (Switching)> prompt. Then type the command enable and the switsh will go into command mode (the password is blank again).

Use the below command to copy from your tftp server:

(Switching) #copy tftp://192.168.50.2/firmware.bin image2

Mode........................................... TFTP
Set Server IP.................................. 192.168.50.2
Path........................................... ./
Filename....................................... firmware.bin
Data Type...................................... Code

Note

To be sure that the unit will accept the file, you should check the names of the firmware slots. Use the bootvar command to find out what they are named. In our case they are image1 in slot 1 and image2 in slot 2. .

Now image2 slot contains 1.1.0.8 Router version:

(Switching) #show bootvar

Now you should redoot the switch:

(Switching) #reload

Are you sure you would like to reset the system? (y/n) y


System will now restart!
