CHAPTER 2
NETWORK REQUIREMENTS
Before installing the 2M46-04R or Fast Ethernet Interface Module,
review the requirements and specifications referred to in this chapter.
The network installation must meet the guidelines to ensure satisfactory
performance of this equipment. Failure to follow the guidelines may
produce poor network performance.
2.1 SmartTrunk
To connect the 2M46-04R to a network so it can take advantage of the
SmartTrunk feature, there are certain rules concerning port connections
and configurations that must be followed for proper operation. Refer to
the Cabletron Systems SmartTrunk User’s Guide for additional
information.
2.2 100BASE-TX NETWORK
The 2M46-04R, with an FE-100TX installed in ports 1 or 2, provides an
RJ45 connection that supports Category 5 unshielded twisted pair (UTP)
cabling, with an impedance between 85 and 111 ohms. The device at the
other end of the twisted pair segment must support IEEE 802.3u
100BASE-TX Fast Ethernet operations. The cabling between the devices
must meet the test criteria for a 100BASE-TX link for the devices to
operate at 100 Mbps. Refer to the Cabletron Systems Cabling Guide for
details.

NOTE
The 2M46-04R with an FE-100TX installed is capable of
operating at either 10 or 100 Mbps. The FE-100TX can
automatically sense the speed of the other device and adjust
its speed accordingly.
