Genuine Dell OEM 100Base-FX NIC

This is a genuine Dell original equipment manufacturer 100Base-FX network interface card designed for low-profile PCIe slots. It operates at 10 or 100 megabits per second over optical fiber using the FX standard. The card includes a low-profile bracket and matches Dell part number U671R. It is supplied new in the condition shown.

For Dell PowerEdge server maintenance

This card suits administrators maintaining compatible Dell PowerEdge servers including models 1950, 2950, 2970 and R210 where a 100Base-FX fiber link is required. It is not for systems that lack a low-profile PCIe slot or that require gigabit or higher fiber speeds. Buyers needing copper-based Ethernet or different form factors should consider other options.

100Base-FX fiber interface decides fit

The single specification that determines compatibility is the 100Base-FX fiber optic interface running at 100 megabits per second. The card uses two optical strands, one for transmit and one for receive, and fits only low-profile PCIe slots. Verify the server model and required fiber connector type before purchase.

Questions about this item

Does the CW595 require a low-profile PCIe slot in the server chassis?

Yes, the card ships with a low-profile PCIe bracket and fits Dell PowerEdge 1950, 2950, 2970 and R210 servers that provide such a slot.

Will the 100Base-FX link negotiate down to 10 Mb/s on older fiber segments?

The adapter supports 10/100 Mb/s speeds, so it can operate at 10 Mb/s when connected to legacy 10 Mb/s fiber infrastructure.

How do I confirm the U671R card has established a 100 Mb/s fiber link after installation?

Check the link LED on the bracket; a steady light indicates a valid 100Base-FX connection, while blinking shows data activity.
