Connecting External Options
Ethernet Connector
The system board in your 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 your 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 44 for additional
information about the Ethernet controller.
Table 9 shows the pin-number assignments for the RJ-45 connector.
These assignments apply to both 10BASE-T and 100BASE-TX
devices.
