10BASE-T Network

10BASE-T Network

When connecting a 10BASE‐T segment to any of the fixed front panel ports of the 2G4082‐25, ensure that the network meets the Ethernet network requirements of the IEEE 802.3‐2002 standard for 10BASE‐T. Refer to the Cabling Guide for details.

Note: If a port is to operate at 100 Mbps, Category 5 cabling must be used. Category 3 cabling does not meet 100 Mbps specifications. For 10 Mbps operation only, Category 3 or Category 5 cabling can be used. Refer to “100BASE-TX Network” on page 2-2 for information about 100BASE-TX networks and cabling.

100BASE-TX Network

The fixed front panel ports of the 2G4082‐25 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.

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 10, 100, or 1000 Mbps and can automatically sense the port speed of the other device and adjust its speed accordingly.

1000BASE-T Network

The 2G4082‐25 supports 10/100/1000 Mbps by means of fixed 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 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.

1000BASE-SX/LX/ELX Network

The optional Mini‐GBICs provide a Gigabit Ethernet connection to the optional network expansion modules 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 Appendix A for further details on Mini‐GBIC specifications.
