Cisco Small Business (CBS & Catalyst) Firmware & Support Hub
Cisco's small office portfolio consists of Cisco Business (CBS110, CBS250, CBS350) and newer Catalyst 1200 / 1300 managed switches, alongside Meraki Go cloud-managed gear. Critical Security Notice: Legacy Cisco RV-series small business routers (such as the RV160, RV260, RV320, and RV340) are approaching or past End-of-Life—check Cisco's Security Advisories and ensure any deployed RV unit is on its final patched release with WAN management strictly disabled.

How to Update Cisco Small Business Firmware Safely
- Search your exact CBS or Catalyst model (for example, CBS250-8PP-E-2G) at software.cisco.com/download/home (no paid Smart Net contract is required for CBS/Catalyst 1200/1300 firmware).
- Log in to the switch web GUI and navigate to Administration > File Management > Firmware Operations.
- Select Update Firmware via HTTP/HTTPS, choose the downloaded .ros or .itb image, and upload it to the Inactive Image slot.
- Set the newly uploaded image as Active After Reboot, save the Running Configuration to Startup Configuration, and reboot the switch.
Cisco Small Business Frequently Asked Questions
Why did my Cisco CBS switch lose all VLAN settings after a power outage?
Like enterprise Cisco IOS switches, CBS and Catalyst 1200/1300 switches keep changes in volatile Running Configuration until you click the blinking red Save icon at the top of the web GUI (copying Running Config to Startup Config).
Do I need a paid Cisco Smart Net contract to download CBS250 or CBS350 firmware?
No. Cisco provides free software and firmware downloads for the Cisco Business (CBS) and Catalyst 1200/1300 series with a free Cisco.com login.
What is the default IP of a Cisco CBS switch if there is no router on the network?
If a Cisco CBS or Catalyst 1200/1300 switch does not receive a DHCP offer within 60 seconds of booting, it assigns itself 192.168.1.254/24.
