I´m trying to upgrade the ePMP2000 from version 3.1 to 3.2.1 using CNUT. I have configure the user and password of the units and the SNMP as v2c with password: private, that is the default password in the units.
I can do ping and access through http to the management of the ePMP2000, but when I try to make the upgrade, allways failed.
