How to Install Enterasys Switch Firmware

Enterasys is a well-established brand that has proven itself with its products and has always gained an important place in the network. This article will show you how to install new firmware on switches that have crashed or are inaccessible.

First of all, I would like to mention that Enterasys was purchased by Extreme Network. Therefore technical support is now provided by Extreme Network.

Alternatively, putty can be used.

In the method described here, the necessary installation will be performed by using XMODEM over COM PORT. You can apply the results in C5-Series, C3-Series, C2-Series, B5-Series, B3-Series, B2-Series, A4-Series, A2-Series switches.

If you don’t have a standard console cable and a built-in COM port, you need a USB-rs232 converter. Tera Term, which is a software that I will carry out as software, will see more of our work.

If you follow the steps in order, first download the Tera Term application and install it on your computer. Once installed, connect your computer to the switch’s console connection with the USB com converter.

Open the Tera Term application and select Serial from the New connection window and select the corresponding COM port from the Port section.

After that, energize the Switch and watch it switch on from Tera Term. When the menu below appears, enter “2“ basın and press enter. If you lose time and miss this menu, turn off the power of the switch and turn on the power again.

Since the Boot “Start Boot Menu” is a non-operating software, this menu will appear at boot even if the system crashes.

When you enter the Boot Menu, you will see the above options. Here, first of all, we will increase the communication speed in order to finish our transactions fast.

For this process;

We will select. 2 Press and Continue with entering.

In this menu, select “8- 115200” ve and confirm with the Y  key.

After this process, our switch which is actively connected with Tera Term will not work, because 9600 Bound was selected at the beginning. Now adjust the application’s settings as you see in the picture below.

The transfer may take a long time. Do not stop here for any reason.

When finished, set the bound rate to 9600 and restart the switch. The switch will be opened with the new firmware.

By the way, if you want to delete everything of a switch that you have forgotten the password, enter the boot menu and select “10 – Restore Configuration to factory defaults (delete config files)”.
