I´ll check it when I could reboot the server. 

greetings, 
You have a BMC ipmi in the first network interface, it can be configured at boot time (I don't  remember if inside the BIOS or pressing cntrl+something during boot)


Hi, 

I have finally rebooted my system and entered inside the BIOS with CTRL+E command. 
I have configured the card and now when I run the command ipmitool lan print I get this information:

ipmitool lan print

                        :     o=OPERATOR
                        :     a=ADMIN
                        :     O=OEM


If I make ping 192.168.1.250 I get response but I can´t do anymore. If I run the racadm commands I still get the errors:

ERROR: RACADM is unable to process the requested subcommand because there is no
local RAC configuration to communicate with.

Local RACADM subcommand execution requires the following:

 1. A Remote Access Controller (RAC) must be present on the managed server
 2. Appropriate managed node software must be installed and running on the
    server


I have tried to access that ip, but I can´t do nothing with it. I have done a port scan and I nothing is listening there, 

What else do I have to do to get this working?

Thanks, 

ESG

Yes you have IPMI and if you are using 1950 Dell, DRAC should be there
too. You can see if you have DRAC or not when the server starts and
before the loading of the OS.

I have 1850s and I am using DRAC for fencing.
