Home / What to do if the core switch loses power
A network switch failure can disrupt business operations by causing connectivity issues, packet loss, and downtime for connected devices. Whether using a managed or unmanaged switch, diagnosing and fixing switch failures requires a structured approach. We have a setup with 2 power supplies "NET 1" = main power and "NET 2" = backup power where NET 1 is the main power supply feeding the cisco switches. If you have backups, you can restore your core switch back to normal Also depending on how your AP's are configured, they may need to be in trunk mode, or if you have a controller then set it up on the same vlan as the controller. Because of the physical limitations of our fiber connections, we only have one trunk interface as the heartbeat interface between the two core switches.
