4 One Media Independent Interface (MII) connector for connecting an external MII
transceiver
Note -
cannot connect to the TPE and MII connectors at the same time.
The Media Independent Interface lets you connect the system to a variety of external
Ethernet transceivers, providing compatibility with different Ethernet wiring types.
When an external transceiver is connected to the MII, the system automatically
activates the MII port and disables the TPE port.
Sun Microsystems offers an MII-to-AUI transceiver as a separately orderable 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.
For instructions on configuring the main logic board Ethernet interface, see "How to
Configure the Standard Ethernet Interface" on page 196. For information about
operating characteristics and configuration parameters for the hme Fast Ethernet
device driver, please see Platform Notes: The Fast Ethernet Device Driver. This
document is available on Solaris on Sun Hardware AnswerBook, which is provided
on the SMCC Supplement CD for the Solaris release you are running.
Additional network interfaces are available through PCI cards, providing connection
to Ethernet, token ring, FDDI, and other network types. For more information, see
"How to Add an Ethernet Interface" on page 198 and the documentation supplied
with the PCI network interface card.
How to Configure the Standard
Ethernet Interface
Before You Begin
You must perform the following tasks:
4 Complete the prerequisite steps in "How to Install the Enterprise 250 Server" on
page 44.
4 Determine which of the two Ethernet ports you want to use; see "About Network
Interface Options" on page 195.
4 Attach a cable to the appropriate Ethernet port; see "How to Attach a Twisted-Pair
Ethernet (TPE) Cable" on page 200 or "How to Attach an MII Ethernet
Transceiver" on page 202.
