Lenovo 00JY940 X710-DA2 ML2 2x10GbE SFP+ network card

SKU CH-NKPE-HMMPN MPN 00JY940

Dual-port 10 GbE SFP+ network adapter using the Intel X710-DA2 controller in ML2 form factor

  • Product weight0.55
  • Dual 10 GbE ports deliver high-throughput server connectivity
  • Intel X710 controller provides reliable low-latency packet processing
  • ML2 form factor fits dense blade and rack chassis
  • SFP+ cages support flexible fibre or copper transceiver choices
  • Light 0.55 kg weight eases installation in crowded racks

Purpose-built server I/O

The Lenovo 00JY940 X710-DA2 ML2 adapter adds two 10GbE SFP+ ports to a compatible server chassis. It targets administrators upgrading rack-mount systems that accept the ML2 form factor. Builders needing a standard PCIe bracket or more than two ports should select a different card.

Thermals and power profile

The card draws power from the ML2 slot and relies on the host system airflow for cooling. With a mass of 0.55 kg it adds minimal load to the chassis. No active fan is present so acoustic output depends entirely on the server fans.

ML2 slot integration

The ML2 edge connector aligns with dedicated server bays, eliminating the need for a full-height bracket. This mechanical match secures the SFP+ cages directly to the chassis rear panel. Systems without an ML2 aperture cannot install this adapter.

Questions about this item

How is the Lenovo 00JY940 installed in an ML2 slot and what step is often missed?

Align the card with the ML2 connector, press firmly until seated, then secure the retention screw; the step often missed is fastening that screw before powering on.

What maintenance or replacement will the X710-DA2 ML2 adapter need later?

Dust the heatsink and SFP+ ports periodically; replace the transceiver modules if link errors appear or speed drops below 10 GbE.

What limit appears first on the 00JY940 under sustained 10 GbE load?

Thermal throttling is the first limit; the compact ML2 form factor relies on chassis airflow to keep the Intel X710 controller within temperature spec.
