Intel® Ethernet Converged Network Adapter X540-T2 Overheats and Cannot Establish a Connection

• Network adapter can be detected by Intel® PROSet Adapter Configuration Utility (Intel® PROSet ACU) but according to it, the link is down even though it says connected.
• On physical removal of the card, there is a slight electrical burnt smell in around the middle of the board.
• Tried on different system and ACU reported the card as overheated.

After performing a hardware isolation and issue still persists, proceed with adapter replacement. Refer to steps below on how to check the version of Ethernet adapter in order to proceed with warranty replacement.

1. Check the Printed Board Assembly (PBA) number of the adapter. Refer to Identify Your Intel® Network Adapter Model Using PBA Number on where to get the PBA number from the physical card.
2. Confirm that the Intel® Ethernet Adapter has YottaMark* and BradyID* stickers on it. The stickers are authentication labels.
3. If the PBA number of the adapter isn't listed on List of Supported Retail Intel® Ethernet Adapters, it's an Original Equipment Manufacturer (OEM) or LAN on motherboard (LOM) adapter. Contact the Manufacturer to request for further assistance.
4. If confirmed that the adapter is a Retail version, submit a request on Warranty Information for replacement.
