Questions buyers ask about this part
- What do I get with the Mellanox ConnectX-5 25GbE Dual-Port, and what else do I need?
- 2 ports at 25Gb/s, in a PCIe 3.0 x8 slot with SFP28 cages. The cages ship empty — optics or DAC are ordered separately and have to be coded for the adapter, which rejects unrecognised modules on some platforms. We quote the card and the optics together.
- Is this Dell Technologies part genuine, and is the warranty intact?
- Yes. We supply through authorized distribution only, so the part carries the full Dell Technologies manufacturer warranty and its firmware update path stays supported. No grey-market stock, no re-labelled drives, no voided warranties.
- Do you offer volume pricing and accept purchase orders?
- The listed price is per unit and indicative; tiered pricing applies at quantity. We accept purchase orders from qualified businesses, government and defence agencies, and educational institutions, with net terms and consolidated invoicing available. Email the quantity you need and we will come back within 48 business hours.
