About this network adapter
A network adapter links a computer or server to a wired network so it can send and receive data. Server versions vary in port count, data rate and connector style: some have fixed copper sockets, others have cages that accept separate optical or copper modules. They are made in full-height and low-profile forms, and as mezzanine or proprietary cards that fit only one server family. Faults show as a port with no link light, connections that drop or run below their rated speed, climbing error counts, or a card the system stops recognising.
Is this the right part?
Find the part number on the label fixed to the card. Check your server model and slot or mezzanine type, make sure the bracket height suits your chassis, and match the port type and speed to the switch it will connect to. The manufacturer's part number for this listing is 503746-B21.
Not sure? Send us the number from the label, or your machine's serial number, and we will confirm the match before you order.
