How to Fix Schneider Electric APC Maximum Connections Reached

For those who prefer the shorter version, the key steps here are:

2. Use the session command to list sessions
3. Use session -d ID# to delete the obsolete sessions

Go log on as you normally would to the web interface.

That will get you to back to work quickly. This happens to many of our devices so it seems not limited to one PDU model.
