Ethernet Connector

The system board in the Netfinity 3500 server contains an

Ethernet

controller

. The controller has an external RJ-45

connector on the rear of the server that is used with a

Category 5 twisted-pair cable. Through this connector, you

can attach an Ethernet network cable to the internal

transceiver in the server.

Attention

The 10BASE-T Ethernet and the 100BASE-TX Fast

Ethernet cabling in the network must be Category 5 or

higher to meet various standards, including

electromagnetic compatibility.

See “Configuring the Ethernet Controller” on page 28

for additional information about the Ethernet controller.

Table 3 shows the pin-number assignments for the RJ-45

connector. These assignments apply to both 10BASE-T

and 100BASE-TX devices.
