When you can't get to the data center and attach a monitor to configure the network settings for the iDRAC, you can use the IPMITool command line utility from an SSH terminal window, like PuTTY.
Listed below are the network configuration commands I found helpful.
Set the iDRAC Network Configuration
Commands:
ipmitool lan set
ipmitool mc reset warm
Example:
[root@APPLIANCE14 ~]# ipmitool lan set 1 ipsrc static
[root@APPLIANCE14 ~]# ipmitool lan set 1 ipaddr 10.0.0.100
[root@APPLIANCE14 ~]# ipmitool lan set 1 netmask 255.255.255.0
[root@APPLIANCE14 ~]# ipmitool lan set 1 defgw ipaddr 10.0.0.1
[root@APPLIANCE14 ~]# ipmitool mc reset warm
List the iDRAC Network Configuration
Command:
ipmitool lan print
Example:
[root@APPLIANCE14 ~]# ipmitool lan print
