1.2 THE ADAPTER FEATURES
The following sections outline the features of the adapters.
1.2.1 Connectivity
The Cabletron Systems adapters connect your computer to an
IEEE 802.3 Ethernet network. The various adapter models
incorporate either an Ethernet 10BASE-T twisted pair port, a thin
Ethernet coaxial BNC port, an SMT type fiber optic port, or an
external transceiver via an AUI cable. All port types provide
access for SNMP network management such as Cabletron’s
SPECTRUM

, Remote LANVIEW

/Windows, or any SNMP-
compliant management software.
1.2.2 Thin Ethernet Port
The adapter’s 10BASE-2 port provides a thin Ethernet BNC
connection to a coaxial segment such as the backbone of a
corporate-wide network, or to a concentrator such as Cabletron’s
MMAC Multi Media Access Center

.
1.2.3 10BASE-T Twisted Pair Port
The adapter’s 10BASE-T twisted pair port employs the RJ-45
eight-pin industry standard connector which must be connected
to a concentrator such as Cabletron’s MMAC Multi Media Access
Center. The 10BASE-T twisted pair port on the adapter has built-
in automatic polarity detection and correction. This means that if
the cable connected to the twisted pair port should have the RX+
and RX– leads reversed, the port circuitry will automatically
detect and correct this problem.
When polarity correction has occurred, the link LED flashes to
indicate that this automatic correction has been performed.
Performance will not be impacted.
