TAILIEUCHUNG - Lab 3.1.9c Rollover Cable Construction

This will be a 4-pair "rollover" cable. This type of cable is typically m (10 ft) long but can be as long as m (25 ft). A rollover cable can be used to connect a workstation or dumb terminal to the console port on the back of a Cisco router or switch. Both ends of the cable built will have RJ-45 connectors on them. One end plugs directly into the RJ-45 console management port on the back of the router or switch. Plug the other end into an RJ-45-to-DB9 terminal adapter. This adapter converts the RJ 45 to a 9-pin female D connector. | Cisco SrsTEMS Lab Rollover Cable Construction Objective Build a Category 5 or Category 5e CAT 5 or 5e Unshielded Twisted Pair UTP console rollover cable. Test the cable for continuity and correct pin-outs the correct wire on the right pin. Background This will be a 4-pair rollover cable. This type of cable is typically m 10 ft long but can be as long as m 25 ft . A rollover cable can be used to connect a workstation or dumb terminal to the console port on the back of a Cisco router or switch. Both ends of the cable built will have RJ-45 connectors on them. One end plugs directly into the RJ-45 console management port on the back of the router or switch. Plug the other end into an RJ-45-to-DB9 terminal adapter. This adapter converts the RJ 45 to a 9-pin female D connector for attachment to the PC or dumb terminal serial COM port. A DB25 terminal adapter is also available to connect with a PC or dumb terminal. This adapter uses a 25 pin connector. The following picture shows a rollover console cable kit that ships with most Cisco devices. For all practical purposes in the last lab when building the straight through jumper putting the second RJ-45 on upside down would have made a rollover cable instead. This cable is called a rollover because the pins on one end are all reversed on the other end as though one end of the cable was rotated or rolled over. Prior to starting the lab the teacher or lab assistant should have a spool of Cat 5 or Cat 5e UTP cable RJ-45 8-pin connectors an RJ-45 crimping tool and a continuity tester available. Work individually or in teams. The following resources will be required 1 - 3 CCNA 1 Networking Basics v - Lab Copyright 2003 Cisco Systems Inc. One to m 10 to 20 ft length of Cat 5 cabling per person or per team Four RJ-45 connectors two are extra for spares RJ-45 crimping tools to attach the RJ-45 connectors to the cable ends An RJ-45 to DB9 female terminal adapter available from Cisco Cabling .
