Network Requirements
Before installing the module, review the requirements and spe cifications referred to in this chapter
concerning the following:
•Port Trunking (Section2.1)
•10BASE-T Twisted Pair Network (Section 2.2)
•100BASE-T Twisted Pair Network (Section2.3)
The network installation must meet the requirements to ensure satisfactory performance of this
equipment. Failure to do so will produce poor network performance.

2.1 PORT TRUNKING FEATURE

Before connecting the module to a network so it can take advantage of the Port Trunking feature,
there are certain rules concerning port connections and configurations that must be followed for
proper operation. Refer to the MATRIX E5 Series Modules Local Management User’s Guide for
additional information.

2.2 10BASE-T NETWORK

When connecting a 10BASE-T segment to any of the module ports (1 through 48), ensure that the
network meets the Ethernet network requirements of the IEEE 802.3 standard for 10BASE-T.
Refer to the Cabling Guide for details.
NOTE: The

NOTE: If a port is to operate at 100 Mbps, Category 5 cabling must be u sed.
Category 3 cabling does not meet 100 Mbps specifications. For 10 Mbps operation only,
Category 3 or Category 5 cabling can be used. Refer to Section 2.3 for information
about 100BASE-TX networks and cabling.
