iDrac Port is not blinking.

First, can you ping the idrac IP address? Sometimes the lights stop working, its rare, but I have seen this happen.
Then, I usually try the network cable going to the idrac in another network port to make sure the cable is good and has an active connection at the other end. if you are sure its a good cable and it can provide link, reboot the system gracefully, then press F2 to go into the bios. Once the system gets to the "bios menu" the second choice is for configuring the idrac. Choose that, then check the network configuration, make sure its set to enabled and that its set to the dedicated nic port, not a shared LOM (integrated nic). 

Waheeds,

The first thing I would look into is if you have the iDrac Enterprise license, as it is required to use the Dedicated iDrac Mgmt port. After that verify that the iDrac Network port is alos set to Dedicated as well. 

Let me know

Dear Sir,

Bundle of Thanks for reply.. There is no any option of dedicated in NIC selection tab. Showing only four options LOM!, LOM2, LOM3..... I have selected LOM 2 It is working properly Sir..... 

Dear Sir,

Thanks a lot for your response, I have just change to LOM2 it is working. And there is no any option for "dedicated" in NIC selection tab....

If you didn't export the license previously then you will have to go to your account portal to get the license details.
