Network Requirements
Before installing the 2H252-25R, review the requirements and specifications referred to in this
chapter concerning the following:
•SmartTrunk (Section2.1)
•10BASE-T Twisted Pair Network (Section2.2)
•100BASE-TX 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 SmartTrunk

To connect the 2H252-25R 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 Enterasys Networks SmartTrunk User’s Guide for additional information.

2.2 10BASE-T NETWORK

When connecting a 10BASE-T segment to any of the 2H252-25R ports (1 through 24), ensure that
the network meets the Ethernet network requirements of the IEEE 802.3 standard for 10BASE-T.
The ports support Category 3 UTP cabling when connected to a 10BASE-T segment. Refer to the
Enterasys Networks Cabling Guide for details.
NOTE: The Enterasys Networks SmartTrunk User’s Guide and Cabling Guide referred
to in the following sections can be found on the Enterasys Networks World Wide Web
site:http://www.enterasys.com
NOTE: If a port is to operate at 10 and 100 Mbps, Category 5 cabling must be used.
Refer to Section2.3 for information about 100BASE-TX networks and cabling.
