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.

NOTE

The Cabletron Systems Cabling Guide and SmartTrunk User’s Guide, referred to in the following sections, can be found on the Cabletron Systems World Wide Web

2.1SmartTrunk

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.

2.2100BASE-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.
