100BASE-TX NETWORK
The fixed front panel ports of the 7H4382-49, 7H4383-49, and 7H4203-72 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. Refer to the Cabling Guide for details.
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.
2.6
1000BASE-SX/LX NETWORK
The optional Mini-GBICs provide a Gigabit Ethernet connection to the port slots on the
7G4270-12 DFE module and the optional NEM to provide fiber-optic connections operating at
1000 Mbps (1 Gbps). Other Mini-GBICs may support different types of cabling connections. The
device at the other end of the fiber-optic connection must meet IEEE 802.3-2002 Gigabit Ethernet
requirements for the devices to operate at Gigabit speed. Refer to
on Mini-GBIC specifications.
2.7
1000BASE-T NETWORK
The 7G4202-30 DFE module provides 30 ports that support 10/100/1000 Mbps via RJ45 front
panel connectors. These connections 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
10/100/1000 BASE-T network requirements for the devices to operate at Gigabit speed.
Note: The fixed ports of the module support Category 5 UTP cabling with an
impedance between 85 and 111 ohms for 100 and 1000 Mbps operation.
Front-panel ports 1 through 30 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.
