How to Attach an MII Ethernet Transceiver

The Media Independent Interface (MII) lets you connect the system to a variety of external Ethernet transceivers, providing compatibility with different Ethernet wiring types.

You can order an MII-to-AUI transceiver from Sun Microsystems as a separate option (order number X467A). A number of third-party MII transceivers are also available for connecting to TX, T4, FX, and AUI-type Ethernet networks.

The procedure below assumes you are connecting the Sun MII-to-AUI transceiver. For third-party transceivers, see the documentation supplied with the transceiver.

Before You Begin

If you are attaching an Ethernet Media Independent Interface (MII) transceiver to the system's standard Ethernet interface, you must have already performed the following task:

If you are adding an Ethernet interface, you must have already performed the following tasks:

What to Do

  1. Locate the appropriate MII Ethernet connector.

    The system comes with one MII Ethernet connector on the rear panel. Your system may also include one or more additional TPE connectors provided via PCI Ethernet interface cards.

  2. Plug the MII Ethernet transceiver into the MII Ethernet connector on the system rear panel.

  3. Attach the network AUI cable to the AUI connector on the MII-to-AUI transceiver.

  4. Lock the AUI connector.

    As viewed from the top, slide the latch to the right to lock the AUI cable to the MII-to-AUI transceiver. Use a flat-blade screwdriver, if necessary.

  5. Connect the other end of the cable to the appropriate network device.

    There are a variety of connector and cabling options available for the AUI connection. See your network administrator if you need more information about how to connect to your network.

    Note -

    You can use only one of the main logic board Ethernet ports. You cannot connect to the main logic board's TPE and MII ports at the same time. For information about connecting to the TPE port, see "How to Attach a Twisted-Pair Ethernet (TPE) Cable".

What Next

If you are installing your system, then complete the installation procedure. Return to:

If you are adding an additional interface to your system, then you need to configure that interface; see:
