Network Information

Commonly known as: Network wire, Ethernet cable, Cat5 cable, the information following will explain the connectivity for Liebert Environmental units. Fundamentally, this section will explain the terms of networking so that you can apply the information to building your own network. The parts and components are discussed in generic fashion since equipment manufacturers and price range of the equipment varies and changes on an almost daily basis. However, the terms themselves stay relatively consistent, so purchasing or discussing your needs with networking personnel remains the same.

What is networking?…

In it’s simplest form, a network can be created when 2 units are connected through communication wires. This simple connection requires a special “crossover” cable which “crosses” the receive and transmit lines (hence, the name of the cable) and is readily available at your local computer store. However, for most applications, the simpler and more generic installation requires network cables and a hub or switch as explained below.

NETWORK CABLING

Twisted Pair Ethernet (10baseT), sometime also called "UTP" from "Unshielded Twisted Pair", is based on using a cable and connectors similar to phone-wiring. The cable is connected via an RJ-45 connectors to the network connection installed in the Air Unit. The wire itself is generally called Category 5 wire.

UTP connector

HUBS AND SWITCHES

The opposite end of the network cable connects each Air Unit to the "hub" or “switch”: these devices amplify and distribute the signal to other connected units. Switches and hubs range in prices from $20 to thousands depending on the application. Most

businesses have standardized on their networking equipment, so there is one probably already installed. Hubs are like mechanical devices where the connections themselves are automatically switched, allowing you to “bus” 2 or more devices easily. In a hub, only 1 device can communicate at a time.

Ethernet uses a bus or star topologyand supports data transfer ratesof 10 Mbps. The Ethernet specification served as the basis for the IEEE 802.3 standard, which specifies the physicaland lower softwarelayers. Ethernet uses the CSMA/CDaccess method to handle simultaneous demands. It is one of the most widely implemented LAN standards iCOM Controls Training and Service Manual •the type of error checking to be usediCOM Control Training and Service Manual There are a variety of standard protocols from which programmerscan choose. Each has particular advantages and disadvantages; for example, some are simpler than others, some are more reliable, and some are faster. From a userspoint of view, the only interesting aspect about protocols is that your computeror device must supportthe right ones if you want to communicate with other computers. The protocol can be implemented either in hardwareor in softwareiCOM Controls Training and Service Manual Understanding IP Addressing: Every computer that communicates over the Internet is assigned an IP address that uniquely identifies the device and distinguishes it from other computers on the Internet. An IP address consists of 32 bits, often shown as 4 octets of numbers from 0-255represented in decimal form instead of binary form. For example, the IP address 168.212.226.204 in binary form is:What is networking?… Network InformationiCOM Control Training and Service Manual HUBS AND SWITCHESUNIT IDENTIFICATION OR ADDRESSING iCOM Controls Training and Service ManualTwisted pair - 10baseT - UTP Cable How To Use The Schematics iCOM Control Training and Service ManualiCOM Controls Training and Service Manual Electrical Schematics182769 Liebert DS iCOM Global Control 8 - 12 Ton iCOM Control Training and Service Manual
