Network Interfaces Available on ARNs

Interface
Description
Ethernet and
Supports the Ethernet and IEEE 802.3 standards that provide LAN connectivity. The
Second Ethernet
ARN can have up to two Ethernet interfaces: one on the base module and one on an
expansion module.
The Ethernet interface on the base module can be a 10BASE-T, a 10/100BASE-Tx, or a
100BASE-Fx. The 10BASE-T can also be used as an expansion module. There are two
ports available for each 10BASE-T: a 10BASE-T and an 802.3 AUI port; however, you
can use only one of these ports (10BASE-T or AUI) on each module at a time.
The 10BASE-T and 10/100BASE-Tx interfaces provide unshielded twisted-pair
support; the 10BASE-T AUI interface provides broadband, baseband, fiber, and
shielded twisted-pair support, depending on the transceiver and cabling you use. The
100BASE-Fx provides fiber support.
Token Ring and
Supports the token ring and IEEE 802.5 standards that provide LAN connectivity. The
Second Token
ARN can have up to two token ring interfaces: one on the base module and one on an
Ring
expansion module.
The token ring base module supports a 9-pin (DB-9) STP token ring interface. The
token ring expansion module supports both a 9-pin (DB-9) STP connector and a UTP
connector; however, you can use only one port (STP or UTP) on the expansion module
at a time.
Both token ring connector types support the 802.5 media access control (MAC)
token-passing protocol, the 802.2 Type 1 (connectionless) protocol, the 802.2 Type 2
(connection-oriented) protocol, and the 16-Mb/s Early Token Release (ETR) protocol
over the appropriate cabling.
