The Review
The PA-220 was designed as a whisper-quiet, fanless entry point into the Palo Alto ecosystem. However, as PAN-OS (the firmware) has evolved from version 8.1 through 10.2, the hardware—specifically the management plane—has struggled to keep pace with the software's increasing resource demands. 1.

Before initiating a firmware update on a PA-220, several preparatory steps are essential. First, always export and save a named configuration snapshot. This ensures that the firewall can be restored if the update fails. Second, verify that the device has sufficient disk space; the PA-220 has limited onboard storage compared to larger models, and old software images should be deleted to make room for new ones. Finally, review the release notes for the specific firmware version. These notes contain "Known Issues" and "Changes in Behavior" that might affect specific network configurations, such as VPN tunnels or complex routing protocols. Troubleshooting Common Issues
