CANNOT DISCOVER DEVICE
Problem Description
GL-1020 devices are discovered automatically using SNMP.
When GL-DocMon cannot automatically discover an installed
GL-1020 controller over the network, the most likely cause is
limitations of the protocols on the supporting workstations. In
some cases, you need to add or update network components.
The following checklist helps you identify the source of the error
and directs to you where you can find more information about
resolving it. If the problem persists after you have followed all of
