CM communication issues

[rstarun]

I have newly installed Communication Manager 6.1 on S8300 (G450). System seems to operate in normal state, without any alarms. But when i use Avaya Site Administration it fails to connect (timeout). I also tried to use Avaya Native Administrator (built in CM java software), it says "connection to switch is timed out".
What could cause such troubles, where should i dig further?

It seems that i was trying to use wrong account for CM administration.
I had to use one of the folowing:
craft - not in my case
dadmin - must be enabled first
customer login - wich was created during installation process

did you open the server access ports, like ssh or telnet ??

SSH was opened by default in new instance of CM 6.
