Installing the Module
Cabling Requirements
10BASE-T Network
When connecting a 10BASE-T segment to the front panel ports of a 9H532-18
module, ensure that the network meets the Ethernet network requirements of the
IEEE 802.3 standard for 10BASE-T. If a port is to operate at 100 Mbps, Category 5
cabling must be used. For 10 Mbps operation only, Category 3 cabling can be
used.
100BASE-TX Network
The 9H532-18 has RJ45 connections that support Category 5 UTP cabling with an
impedance between 85 and 111 ohms for 10 and 100 Mbps operation. 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. Refer
to the Cabletron Systems Cabling Guide for details.
100BASE-FX Network
The 9H531-18 supports 100BASE-FX. When connecting a
100BASE-FX segment to any of the front panel ports, ensure that the network
meets the optical performance requirements for 100BASE-FX IEEE 802.3u
standard.
The 9H531-18 supports multimode fiber cables at the 1300 nm wavelength, at
lengths of up to 2 km.
1000BASE-SX/1000BASE-LX Network
For information about 1000BASE-SX and 1000BASE-LX, see Appendix A.
