i am using openmanage network manager 5.1 to manage PowerConnect 7048 switches.

i am able to manage/monitor the switches using SNMP without issues.

however when i use telnet/ssh it keeps throwing errors saying "1 did not respond to authentication. please click here for list of devices that did not respond. will attempt to manage these as default devices." 

the document however doesnt say what should be written in the enable ID field.
