Intel Ethernet Controller X540-AT2
Dual-port 10GBASE-T MAC/PHY controller silicon for server boards and NICs. Confirm exact product label and revision before applying specifications.
IDENTIFICATION: Confirm manufacturer PID, hardware revision, device ID or module suffix. Nominal standards/link rates are not measurements of payload performance.
Exact specifications and compatibility
| Dedicated subcategory | Ethernet controllers and PHYs |
|---|---|
| Exact product/model | Intel Ethernet Controller X540-AT2 |
| Bus, ports and physical interface | PCIe 2.1 x8 host connection; board design routes two 10GBASE-T ports to magnetics/RJ-45. |
| PHY, radio or protocol | Integrated dual-port copper 10GBASE-T controller/PHY. |
| Nominal rate (not measured) | Two nominal 10Gb/s Ethernet ports when used in a supported board implementation; not chip-level benchmark data. |
| Measured throughput | No measured benchmark is claimed for a physical specimen. A valid result must record host/peer, link partner, media/cable, driver/firmware, traffic pattern, test tool and duration. |
| Drivers, OS and firmware | Board/OEM provides firmware/NVM and OS support; Intel ixgbe driver family commonly supports X540 devices. |
| Compatibility | Requires host board power, clock, PCIe routing, magnetics, thermal design and validated NVM; package alone is not a field-replaceable adapter. |
| Variant warning | X540-AT2 is silicon identity; X540-T2 retail adapter and OEM onboard implementations can differ in EEPROM, magnetics and features. |

Archival, ESD and preservation notes
Archive chip top-marking, stepping, board design and thermal pads. ESD-safe handling; record assembly rather than treating bare silicon as a plug-compatible card.
