100BASE-TX Network
Fixed front panel ports of the 7H4382-25 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.
1000BASE-SX/LX Network
Optional Mini-GBICs provide a Gigabit Ethernet connection to the optional 7G-6MGBIC
interface module to provide fiber-optic connections operating at 1000 Mbps (1 Gbps). 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 Appendix A
for further details on Mini-GBIC specifications.
1000BASE-T Network
Optional Mini-GBICs can also provide a copper-wire connection that supports Category 5
UTP cabling. The device at the other end of the twisted pair segment must meet
IEEE 802.3-2002 1000BASE-T Fast Ethernet network requirements for the devices to
operate at 1000 Mbps. Refer to Appendix A for further details on Mini-GBIC
specifications.
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.
