ThinkPad Micro-Ethernet Adapter

The Lenovo EX280 Gen 2 converts the proprietary micro Ethernet port on select ThinkPad notebooks to a standard RJ45 jack. It requires no driver installation and works immediately on supported systems. The 80 mm cable keeps the dongle compact for travel.

Mobile professionals needing wired LAN

Designed for users who need PXE boot, Wake-On-LAN or MAC address pass-through on compatible ThinkPad models listed by Lenovo. It will not fit laptops that lack the dedicated micro Ethernet connector, so buyers with only USB-C or full-size RJ45 ports should look elsewhere.

Verify ThinkPad model compatibility

Before ordering, confirm your notebook appears in the supported model list, which covers specific X, T, P, L and X1 Carbon/Yoga generations. The adapter draws power from the micro Ethernet port itself, so no external supply is required. Ensure the 80 mm reach suits your docking or desk layout.

Questions about this item

Which ThinkPad models have the micro Ethernet port this adapter plugs into?

Compatible models include X13 Gen 2, L13 Gen 2, T14s Gen 2, X1 Carbon 8th Gen, X1 Yoga 5th Gen, T14 Gen 2, P14s Gen 2 and others listed in the compatibility table.

Will the 80 mm cable reach the RJ45 jack on a dock or wall plate?

The 80 mm pigtail adds about 8 cm of reach; it is designed for direct laptop-side use rather than spanning a desk.

How do I confirm PXE boot and Wake-on-LAN are active after connecting?

Enter BIOS on the supported ThinkPad, enable PXE and Wake-on-LAN for the adapter MAC, then verify the link LEDs illuminate when the cable is plugged in.
