NBR-SERIES Installation Guide Page C-1
APPENDIX C
NETWORK PLANNING AND CONFIGURATION
This appendix contains general networking guidelines. Before attempting
to install the NBR or any additional EPIMs or BRIMs, review the
requirements and specifications outlined in this appendix.
C.1 NETWORK CABLE REQUIREMENTS
Take care in planning and preparing the cabling and connections for your
network. The quality of the connections, the length of cables, and other
conditions of the installation play critical roles in determining the
reliability of your network.
Refer to the sections below that apply to your specific network
configuration.
C.1.1 10BASE-T Twisted Pair Network
When connecting a 10BASE-T Twisted Pair Segment to an EPIM-T,
ensure the network meets the following requirements:
• Length - The IEEE 802.3 10BASE-T standard requires that
10BASE-T devices transmit over a 100 meter (328 foot) link using
22-24 AWG unshielded twisted pair 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 maximum link length to 200 meters, regardless of
the cable type.

CAUTION
Your network installation must meet the conditions, guidelines,
specifications, and requirements included in this appendix to
ensure satisfactory performance of this equipment. Failure to
follow these guidelines may produce poor network
performance.
