I'm experiencing an issue while upgrading the firmware of a switch to the latest version, 4.1.3.36. The reboot process has taken hours, but it still hasn't been completed and no percentage appears to see the reboot process. Checking the CLI status shows that the old version remains active and will only switch to inactive after a successful reboot.
The setup involves stacking switches, but one of the switches is running a different firmware version, so I'm trying to upgrade all the switches to the latest version to match each other. Notably, stacking two switches with version 4.0.0.93 works without issues. However, when configuring a third switch with a different version, it gets stuck in the reboot process after applying the stack configuration, leading to a connection timeout and losing access to both the GUI and console.
Would trying a different firmware version be advisable in this scenario? Or should I stick to 4.0.0.93? Or what version is recommended for this model Catalyst 1300-48P-4X?
