Ports Requiered to have fully access to Blade ILOM functionalities X6270 M2 Blade

Hello Community,

We are placing a new toy based on this HW

System Configuration: SUN MICROSYSTEMS SUN BLADE X6270 M2 SERVER MODUL
BIOS Configuration: American Megatrends Inc. 08050203 12/16/2010
BMC Configuration: IPMI 1.5 (KCS: Keyboard Controller Style)

The issue is as follow.

I do connect to the Blade ILOM thru the Chasis IP or the Blade Itself IP ( webserver )

when I try to Launch Remote Console in ILOM GUI nothing is happening, we have discarded pop-up bockers and so on and we think it is related with some ports blocked on the Firewall of the switch, since openning all the

ports on the switch is not an option...
