Ethernet Connector
The system board in your Netfinity 5000 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 3, 4, or 5 twisted-pair cable. The connector enables an Ethernet
network to attach to the internal transceiver in your server.
Note: The 100BASE-TX Fast Ethernet standard requires that the cabling in the
network be Category 5 or higher.
See “Configuring the Ethernet Controller” on page 32 for additional information
about the Ethernet controller.
Table 10 shows the pin-number assignments for the RJ-45 connector. These
assignments apply to both 10BASE-T and 100-BASETX devices.
