  • FeaturesDesktop
  • Dimensions5.0 in x 0.8 in x 5.0 in
  • Weight0.22 lb
  • Gigabit speeds over existing CAT-5 cabling
  • PCI Express 1.1 single-lane interface at 2.5 Gbps

What this card does

The ULANSeN 8541588194 adds a single RJ-45 port for 10, 100 or 1000 Mbps Ethernet over a PCI Express 1.0a slot. It uses the Broadcom BCM5751 controller with an integrated transceiver and on-chip buffer memory. The half-height bracket is included for low-profile chassis.

Installation notes

The card fits a standard PCI Express x1 slot and needs no auxiliary power. Drivers are available for Windows 2000 through Windows 7, Linux kernels 2.4 and 2.6, FreeBSD, ESX 3.x and several older network operating systems. Automatic MDI crossover and pair-swap correction simplify cabling.

Who should buy it

Suitable for restoring wired connectivity to a legacy desktop or server that lacks onboard Gigabit Ethernet and runs one of the listed operating systems. Not for builders who need multi-gigabit speeds, multiple ports, or driver support for current Windows or Linux releases.

商品問答

How do I confirm the BCM5751 is operating at 1000 megabits_per_second after installing the 8541588194 card?

Check the link speed in your operating system network settings; it should report 1000 Mbps full-duplex. The card's auto-negotiating 10/100/1000BASE-T transceiver and IEEE 802.3ab compliance handle speed detection automatically on the RJ-45 port.

Does the ULANSeN 8541588194 package include the half-height bracket shown in the highlights, or must I buy it separately?

The manufacturer highlights list an included half-height bracket, so both full-height and low-profile mounting options are supplied in the box. No separate bracket purchase is required for standard or slim chassis installations.

Which PCI Express version does the 8541588194 need — 1.0a or 1.1 — and will it work in a newer 2.0 or 3.0 slot?

The card is PCI-E v1.0a compliant and uses the PCI-Express 1.1 form factor with a 2.5Gbps line rate; it is backward compatible with newer PCIe 2.0, 3.0 and later slots at the 1.1 signalling speed.
