Why is my stack switch not showing online on Nebula?

If your third stack switch is not showing online on Nebula, the following could be the causes and solutions:

Possible Issues:

1. DHCP Issue: The switch might not be obtaining a DHCP address, which prevents it from connecting to Nebula.
2. Firmware Outdated: An outdated firmware version can cause instability and connectivity issues.

Solution:

1. Verify DHCP and VLAN Settings:
   • Ensure that the DHCP server is properly configured and that the switch is in the correct VLAN.
   • Check if the switch is receiving an IP address from the DHCP server.
2. Update Firmware:
   • Visit the official Zyxel support site: Download the latest firmware version.
   • Update the firmware to version 4.90 Patch 4 for improved stability and connectivity.
