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
