How to Update Firmware on Your Ethernet Switch

Firmware updates sound scary, but they do not have to be. Think of firmware as the brain inside your switch. When you update it, you help that brain stay sharp, safe, and ready for new tasks. 

Most updates are smooth when you take them slowly. Back up your settings, check the model number twice, and plug the switch into reliable power. That is half the battle won already. 

Here, we will walk through seven friendly ways to get the job done. We will keep steps simple, avoid jargon, and share small tips you can trust. If you are nervous about breaking something, breathe. 

By the end, you will know which method fits your gear and your comfort level.

1) Use The Switch's Web Dashboard

Firstly, you need to start up a web browser, enter the IP address of the switch, and log in with your administrator account. Once there, go to the Administration, Maintenance, or Firmware menu. Go to the official site of the vendor, download the latest firmware file, and upload it using the dashboard.

This is mostly true of Ethernet switches, which are networking devices designed to forward data packets between devices within a local area network (LAN) by using MAC addresses to determine the correct destination.

This backup is to make sure that you can easily revert to your settings in the event of anything going wrong.

2) Update With The Vendor's Desktop App

Many brands ship helper apps for Windows or macOS. Install the app, let it scan your LAN, and pick your switch. The tool often grabs the right file and reduces mismatch risk. 

Follow the prompts, keep the cable connected, and wait for the “done” message.

  • Auto-detects your switch on the network
  • Checks for the newest firmware build
  • Guides you through backup and reboot steps

3) Use A USB Port If Your Model Supports It

Some pro and smart switches include a front USB slot. Download the firmware, copy it to a clean FAT32 drive, and insert it. In the menu, choose “upgrade from USB” and select the file. 

This method shines when your switch lives on an isolated network. Label the stick, save a copy of your config on it, and eject it safely after the upgrade.

4) Command-Line Over SSH or Console

SSH into the switch or use the console cable. Upload the image by TFTP, SFTP, or SCP. Set the new image as the boot target, verify the checksum, and reload in a quiet window. 

Save your config first. Keep the old image as a fallback if your platform supports dual banks.

  • Works well for rack gear and scripted setups
  • Let's you verify checksums before flashing
  • Pairs nicely with change windows and logs

5) Schedule Maintenance Via The Cloud Portal

Many modern switches tie into a cloud dashboard. There, you pick a time window, choose a firmware track, and push updates to one or many devices. 

This helps in branch offices or schools. Use tags to group sites, check pre-update health, and add a short note so teammates know the plan. After the job, skim the change log and confirm ports and PoE look normal.

6) Zero-Touch Updates For New Deployments

Zero-touch can save days. The switch phones home to the portal, learns its name and config, and grabs the right image. Pilot a small group, then roll by waves. Keep spares, clear labels, and a rollback plan in case a site has slow links or power blips.

  • Ship devices straight to sites and auto-upgrade
  • Pull configs and images on first boot
  • Reduce hands-on work and travel time

7) Work With Long-Term Support (LTS) Firmware

Stable networks need stable code. Many vendors offer LTS builds that get security fixes without risky new features. If uptime matters more than extras, pick LTS and stick to it. 

Read the notes, track known issues, and plan upgrades on a steady cycle, like every quarter. Keep a simple sheet of models and serials so you always know what runs where.

Conclusion


Updating firmware is not about chasing hype. It is about safe, steady care for your network. Use a backup first, adopt a process that best suits your switch, and avoid the temptation to go clicking as the upgrade process continues. 

Have a little run book containing your steps, file name, and date. That note saves time later. Choose LTS builds when you can, and batch changes during your quiet hours. If something feels off, pause and read the notes again. 

With a calm plan and the right file, your switch will do its job better, and you will sleep more easily. Those small moments add up, sustain progress, and make the work feel lighter, one careful update at a time, every day
