100BASE-TX Network
NOTE: If a port is to operate at 100 or 1000 Mbps, Category 5 cabling must be used.
Category 3 cabling does not meet the 100 or 1000 Mbps specifications. For 10 Mbps
operation only, Category 3, Category 4, or Category 5 cabling can be used. Refer to
Section 2.3
networks and cabling.
2.3
100BASE-TX NETWORK
When connecting a 100BASE-TX twisted pair segment to one of the fixed ports (1 through 6), or
to an optional Ethernet expansion module, use Category 5 UTP cabling. The device at the other end
of the twisted pair segment must meet IEEE 802.3u 100BASE-TX Fast Ethernet network
requirements for the devices to operate at 100 Mbps.
NOTE: The fixed ports of the device support Category 5 UTP cabling with an
impedance between 85 and 111 ohms for 100 Mbps operation.
The device is capable of operating at either 10 or 100 Mbps. The device automatically
senses the speed of the other device and adjusts its speed accordingly when
Auto-Negotiation is enabled.
2.4
100BASE-FX NETWORK
When connecting a 100BASE-FX multimode fiber-optic segment to an MT-RJ port connector on
an optional Ethernet expansion module, the port must meet the optical performance requirements
of the 100BASE-FX, IEEE 802.3u standard. The device at the other end of the segment must also
meet the 100BASE-FX Fast Ethernet network requirements to operate at 100 Mbps.
2.5
1000BASE-SX/LX NETWORK
The fixed front-panel port slots (1 through 6) of the 1G587-09 and the ones on the optional
1G-2MGBIC expansion module provide fiber-optic connections operating at 1000 Mbps (1 Gbps)
via optional Mini-GBICs. Depending on the Mini-GBIC used, different types of cabling
connections are supported. 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.
2.6
1000BASE-T NETWORK
When connecting a 1000BASE-T Gigabit Ethernet twisted-pair segment to one of the 1G582-09
fixed ports (1 through 6) or to an optional Ethernet expansion module that supports 1000BASE-T,
use Category 5 UTP cabling. The device at the other end of the twisted pair segment must meet
IEEE 802.3z 1000BASE-TX Gigabit Ethernet network requirements for the devices to operate at
1000 Mbps.
