CHAPTER 2

INSTALLATION

REQUIREMENTS/SPECIFICATIONS

This Chapter describes cable requirements, network guidelines, and operating
specifications for the RMIMs. Be sure that you read this chapter before you
install the RMIMs. Your network must meet the requirements and conditions
specified in this chapter to obtain satisfactory performance from this equipment.
Failure to follow these guidelines could result in poor network performance.

2.1

NETWORK CABLE REQUIREMENTS

Take care in planning and preparing the cabling and connections for your
network. The quality of the connections and the length of cables are critical
factors in determining the reliability of your network. The following sections
describe cable requirements for each media type.

2.1.1

10BASE-2 Thin-Net Network Requirements

When connecting a 10BASE-2 thin-net coaxial segment to the CXRMIM or
EPIM-C, your network must meet the following requirements:

Cable Type

50 ohm RG-58A/U type coaxial cable must be used when making up a thin-net
cable segment.

Length

The thin-net segment must be no longer than 185 meters.

Terminators

A 50 ohm terminator must be connected to the far end of each thin-net segment.
