Netfinity 3500 - Ethernet Connector

Applicable to: World-Wide


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" 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.

Ethernet Controller Operation Mode Switch

When you want to change the Ethernet controller operation mode from Normal to MAC Disabled, you must change the setting of configuration switch 6.

1. Locate the configuration switches on the system board. For more information, refer to the label inside the server, or see "System Board".
2. To set the Ethernet controller operation mode to the appropriate value, set switch 6 as shown in the following illustration. It might be helpful to use the end of a small screwdriver to set the switch.

Note: In the following illustration, MAC represents media access control. This refers to the Ethernet controller address.

3. Move the switch to the ON position.
4. Make the required adjustments to the Ethernet controller address.
5. Move the switch back to the OFF position.
6. After changing configuration switch settings, you must reconfigure the server. After reassembling the server (see "Completing the Installation"), use the Configuration/Setup Utility program to reconfigure the server. For more information, see "Configuration/Setup Utility Program Menus".
