How To Attach An Mii Ethernet Transceiver - Sun Microsystems Enterprise 250 Owner's Manual

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:
Completed prerequisite steps in "How to Install the Enterprise 250 Server" on
page 13
If you are adding an Ethernet interface, you must have already performed the
following tasks:
Installed the system; see "How to Install the Enterprise 250 Server" on page 13
Installed a PCI Ethernet interface card; see "How to Install a PCI Card" on
page 87
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.
