ESX-1320/ESX-1380 Installation GuideB-1APPENDIX BETHERNET CABLING REQUIREMENTSThis chapter contains general networking guidelines. Before attemptingto install the ESX, review the requirements and specifications outlined inthis chapter.B.1 NETWORK REQUIREMENTSTake care in planning and preparing the cabling and connections for yournetwork. The quality of the connections, the length of cables, and otherconditions of the installation play critical roles in determining thereliability of your network.Refer to the sections which follow that apply to your specific networkconfiguration.B.2 10BASE-T TWISTED PAIR NETWORKWhen connecting a 10BASE-T segment to the ESX-1320, ensure thenetwork meets the following requirements:• Length: The IEEE 802.3 10BASE-T standard requires that10BASE-T devices transmit over a 100 meter (328 foot) link using22-24 AWG unshielded twisted pair wire. This is supported byCabletron Systems. However, cable quality largely determinesmaximum link length. If you use high quality, low attenuation cable,you can achieve link lengths of up to 200 meters. Cable delay limitsthe maximum link length to 200 meters.NOTEYour network installation must meet the conditions, guidelines,specifications, and requirements included in this chapter toensure satisfactory performance of this equipment. Failure tofollow these guidelines may result in poor networkperformance.NOTELosses introduced by connections at punch-down blocks andother equipment reduce total segment length. For eachconnector or patch panel in the link, subtract 12 meters fromthe total length of your cable.
