4-Port 10/100 Base-TX Ethernet PCI Adapter (FC 4961)

The 4-Port 10/100 Base-TX Ethernet PCI Adapter provides attachment at 10 Mbps or 100 Mbps to a carrier sense multiple access/collision detection (CSMA/CD) Ethernet local area network (LAN) for systems designed to operate with the PCI bus interface. The adapter uses the IEEE-802.3u standard for communications. The adapter will occupy a single slot but will appear to the system to be four unique 10/100 Ethernet adapters.

The adapter supports connections to 10BaseT or 100BaseTx on unshielded twisted pair networks through an RJ-45 connector.

If you are installing a new feature, ensure that you have the software required to support the new feature and that you determine if there are any existing prerequisites. To do this, use the IBM® Prerequisite Web site at http://www-912.ibm.com/e_dir/eServerPrereq.nsf .

Viewing the LEDs

The adapter has two LEDs for each port to provide status on the adapter's operation. The LEDs are visible on the mounting bracket at each port's connector. They indicate the following conditions when lit:

• Green LED (1) - indicates 100 Mbps operation
• Yellow LED (2) - indicates transmit or receive activity
