I have a fibre cable ring operating and periodically I need to break this ring at the same switch in order to add another unit as the site grows. Now everything stays online as it should via the uplink but we have a device in a port on this switch that is connected to a breaker (emergency alarm) that trips every time I disconnect the downlink. It trips again when we reconnect the downlink also. I’m at a loss as to why this happens.
I’m not sure it’s anything to do with the network but I’ve got to rule it out.
Any help is appreciated.
