Cabling Requirements
10BASE-T Network
When connecting a 10BASE-T segment to the front panel ports of a 9H532-24 or a
9H533-24 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 9H532-24 and the 9H533-24 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 9H531-24 and 9H539-24 support 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 9H531-24 supports multimode Þber cables at the 1300 nm wavelength, at
lengths of up to 2 km.
The 9H539-24 supports single mode Þber at the 1300 nm wavelength. Class 1
lasers are used to support single mode 9/125 micon Þber cables up to 15 km in
length.
