100Base-Tx Network - Enterasys Matrix 7H4385-49 Hardware Installation Manual

100BASE-TX Network

The fixed front panel ports of the 7H4385‐49 provide a connection that supports Category
5 UTP cabling. The device at the other end of the twisted pair segment must meet
IEEE 802.3‐2002 100BASE‐TX Fast Ethernet network requirements for the devices to
operate at 100 Mbps. The fixed front‐panel ports also support the 802.3af‐2003 standard
for Power over Ethernet (PoE) power sourcing applications over existing cabling. For
more information about PoE, refer to Appendix
Note: The fixed ports of the module support Category 5 UTP cabling with an impedance
between 85 and 111 ohms for 100 Mbps operation.
The module is capable of operating at either 10 or 100 Mbps. The module automatically
senses the speed of the other device and adjusts its speed accordingly.
