We planned the Core switch stack so downlink to distribution switch can configure as active-standby link. MX configured as HA, this why we planned to stack the core for redundancy purposes.
The topology should look like this.
The new switch have upgraded to latest stable version same as version of production switch. we don't configure anything except hostname, IP Address (DHCP), VLAN and uplink port just for reach the internet via server farm environment. After upgrade the firmware, we turn off the all switchs (MS410) then plug the physical stack cable create a ring topology, connect the uplink (here, it should look like the topology but we didn't, we followed the guide anyway) and power on the switch. when we powered on the switch, first switch can connect to dashboard but the second switch can't connect to dashboard. at Switches > Monitor > Switch Stacks, potentials stack was not found and then try to configure stack manually but still nothing happened.
Wondering if anyone has experienced a similar issue, and there's maybe something I've missed?
is configured the vlan or anything make the stack member can't connect to dashboard?
should i try give internet connection the second switch ?
After bringing up the stack, how long did you wait? How did you verify the Cloud Connectivity? Did you check the colors of the LEDs on the switch?
Sometimes, my experience is that the switch will report Unable to Connect in the dashboard, eventhough it is in fact conencted. Usually it's due to some caching going on, either directly in your local browser, or at the Meraki End.
hm, maybe you have to reset the not working switch to factory defaults and get it online directly to a internetconnection again.
And you then leave it for a couple of hours. Further more you can get in touch with support to verify all is fine, after reset and keeping it online some hours as they can see more details in their dashboard.
Had the quite similar problem and the Meraki SE saw more details and told me I plugged the switch off too fast (~45min). But he also said 30-45min is normally the maximum time range to do its initial update.
