CHAPTER 2
NETWORK REQUIREMENTS
This chapter contains general networking guidelines. Before attempting to use the 8H02-16 or to install a Fast Ethernet Interface Module (FE-100TX or FE-100FX), review the requirements and specifications outlined in this chapter.
2.1NETWORK REQUIREMENTS
The network installation must meet the guidelines included in this chapter to ensure satisfactory performance of this equipment. Failure to follow these guidelines may produce poor network performance.
Refer to the following sections that apply to your specific network configuration.
2.1.110BASE-T Twisted Pair Network
When connecting a 10BASE-T twisted pair segment to any of the 8H02-16 ports (Interfaces 1 through 14), ensure the network meets the following requirements:
Length
The IEEE 802.3 standard for 10BASE-T requires that 10BASE-T devices transmit over a 100 meter (328 foot) link using 22–24 AWG Unshielded Twisted Pair (UTP) wire. However, cable quality largely determines maximum link length. If you use high quality, low attenuation cable, you can achieve link lengths of up to 200 meters. Cable delay limits the maximum link length to 200 meters.
Losses introduced by connections at punch-down blocks and other equipment reduce total segment length. For each connector or patch panel in the link, subtract 12 meters from the total length of the cable.
