Recently we’ve started to get the following alerts on our Sentinels (we have three).
No network connection available
No ethernet ports are connected.
We don’t know what causes it, but it resolves itself.
All Sentinels have two network cables plugged in, and all six cables are brand new.
We don’t notice any loss of connectivity, and we don’t get the “Redundancy Lost” alert beforehand, so it’s extremely unlikely to be an issue with the physical ports/cables.
We are also having an issue with Network connection 1 not being connected. In fact it says it is unplugged. This happened after a power outage recently.
I’ve tried different cables (they were verified working), different ports on the Ethernet Switch (verified working before use) even shut down the NAS and powered it up again.
We also have an external Drive connected to the NAS via USB, we disconnected that as well and it did not fix the problem. We even updated the NAS to the latest version, this dod not fix the issue either.
I read above that it fixes itself for some reason. I’ll keep an eye on it, but it has been like this for about 5 days now.
We are having the same issue and we are not able to get a full backup because we get disconnected. Have the group of us configured something incorrectly?
Grab any drivers that need updating, then install them.
You may have to reconfigure your IP settings after doing driver updates, but probably not. If you do, just hook the Sentinel up to a PC directly and set your PC to DHCP and then remote desktop in to the IP on the Sentinel’s LCD panel.
