Firmware Update Process

Now, let's dive into the step-by-step firmware update process for Cisco SG350 Switches:

Step 1: Accessing the Switch Interface

To begin, open your preferred web browser and enter the IP address of your Cisco SG350 Switch into the address bar. Press Enter to access the switch interface. You will be prompted to enter your login credentials.

Step 2: Navigating to the Firmware Update Section

Once logged in, navigate to the administration section of the switch interface. Look for the "Firmware Management" or similar option in the menu.

Step 3: Uploading the Firmware File

In this step, you will upload the downloaded firmware file to the switch interface. Click on the "Choose File" button and select the firmware file from your local drive. Once selected, click on the "Upload" or similar button to initiate the firmware upload process.

Step 4: Verifying the Firmware

After the upload process is complete, the switch will verify the firmware file. This process ensures that the firmware file is valid and can be applied to the switch without any issues. Be patient, as this may take a few minutes.

Step 5: Applying the Firmware Update

Once the firmware file is verified, you will have the option to apply the update. Click on the "Apply" or similar button to start the firmware update process. Do not interrupt the process or power off the switch during this time.

Step 6: Monitoring the Update Progress

The switch interface will display the progress of the firmware update. It is essential to monitor this process to ensure that it completes successfully. Avoid making any configuration changes or restarting the switch while the update is in progress.

Step 7: Verifying the Update

After the firmware update is complete, it is crucial to verify that the switch is running the latest firmware version. Navigate to the firmware information section within the switch interface and confirm that the updated version is displayed.

Firmware Rollback Procedure

In the event of any issues or undesirable behavior after a firmware update, it may be necessary to perform a rollback. Follow these steps to rollback the firmware of your Cisco SG350 Switch:

Step 1: Accessing the Switch Interface

Similar to the firmware update process, access the switch interface by entering the IP address into your web browser's address bar. Enter your login credentials to proceed.

Step 2: Locating the Firmware Rollback Options

Navigate to the administration section of the switch interface and search for the "Firmware Management" or similar option. Look for the firmware rollback functionality within this menu.

Step 3: Selecting the Previous Firmware Version

Within the firmware rollback section, you should have the option to select a previous firmware version. Choose the version you wish to rollback to from the available list. Ensure that you select a stable and previously installed firmware version.

Step 4: Initiating the Rollback Process

Once you have selected the desired firmware version, click on the "Rollback" or similar button to initiate the rollback process. Be patient, as this may take some time to complete.

Step 5: Verifying the Rollback

After the rollback process is finished, navigate to the firmware information section to confirm that the switch is running the rolled-back firmware version. Ensure that the previous version is displayed correctly.
