100BASE-TX Network

100BASE-TX Network

The fixed front panel ports of the 7G4285‐49 and 7G4205‐72 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 C.

Note: The fixed ports of the modules support Category 5 UTP cabling with an impedance between 85 and 111 ohms for 100 Mbps operation.

The modules are capable of operating at either 10, 100, or 1000 Mbps. The module automatically senses the speed of the other device and adjusts its speed accordingly.

1000BASE-T Network

The 7G4285‐49 and 7G4205‐72 support 10/100/1000 Mbps via fixed RJ45 front panel connectors. These connectors support copper wire connections that can operate up to 1000 Mbps. The device at the other end of the twisted pair segment must meet IEEE 802.3‐2002 network requirements for the devices to operate at Gigabit speed.

Note: The fixed ports of each module support Category 5 UTP cabling with an impedance between 85 and 111 ohms for 100 and 1000 Mbps operation and can automatically sense the port speed of the other device and adjusts its speed accordingly.
