Introduction

This book contains guidelines for installing Ethernet network hardware components and Ethernet segment construction and routing.

Cable routing and installation work must be done by qualified personnel. The National Electric Code (NEC), the EIA/TIA 569 standard, EIA/TIA 568-A standard, EIA/TIA 607 standard, and local regulations governing communications wires must be adhered to.

NCR supports only the communication network components that are specified in this document.

Caution: Cables should not be routed near devices such as fluorescent light ballasts, near magnetic devices such as motors found in fans, air compressors, and air conditioners, or in cable trays (Walker ducts) with AC power wiring. Refer to Layout Guidelines.

Prior to work on any cable, check the voltage between the cable conductors and the local earth. If that voltage exceeds 30 volts rms, an electrical fault is indicated; this fault must be corrected before you proceed.

Do not work on network wiring during a lightning storm.
