2-2 Network Requirements
2.3 100BASE-TX NETWORK
The fixed ports (ports 1 through 24) of the 2H252-25R provide an RJ45 connection that supports
Category 5 UTP cabling. The device at the other end of the twisted pair segment must meet IEEE
802.3u 100BASE-TX Fast Ethernet network requirements for the devices to operate at 100 Mbps.
Refer to the Enterasys Networks Cabling Guide for details.
NOTE: The fixed ports of the 2H252-25R support Category 5 UTP cabling that has an
impedance between 85 and 111 ohms.
The 2H252-25R is capable of operating at either 10 or 100 Mbps. When the port is
configured for Auto-Negotiation, the 2H252-25R automatically senses the speed of the
other device and adjusts its speed accordingly.
