Patch cables
Easy steps for creating patch cables:
When you are making a specific kind of connection it requires a certain type of cable configuration.Patch cables are cables that have standard connectors,often referred to as RJ-45 connectors,on both ends of the cable. Although there are a many variations of patch cables,there are three patch cable standard configurations that are common in the industry: - Straight-through cables: Used to connect end systems to wall jacks, and active devices to patch panels ports (hubs,switches, etc) - Cross connect cables (a.k.a. cross-over):Used for connecting two hubs/switches together or two active devices together. - Roll Over cables: Many manufacturers use roll over cables to connect a computer to the console port of a router, switch,bridge or hub for management purposes. The configuration listed in this document works with all cisco devices. For other manufacturers refer to the specifications listed in their documentation. 1. Cut the desired length of cable and typically leave a small amount of slack. 2. Take the cable and strip off the sheath at each end (about 1 ½ inches so you can manipulate the wires 3. Separate out each pair of wires (so it resembles a fan). 4. Using the charts below, arrange each individual wire and line them up correctly, side by side, as close as possible with the left most wire being the one to go in the left most slot of the connector.This takes practice so be patient, and be sure to do only one side of the cable at a time. 5. After, you have lined each of the wires according to the numbering scheme, slide them into the connector (RJ-45 connector).The connector should always have the copper lines facing upwards,and the open end facing toward you. [hint: Inserting the wires with a little downward pressure helps spread the wires out and slide into the slots easier] 6. The wires must be inserted all the way so the copper tips can be seen clearly from the front end of the connector (the tips are butted up tightly against the end of the slot). The sheath should be inside the connector about ¼ inch. 7. Now you have to crimp the wires using a Crimper tool.This is completed by inserting the connector into the slot of the Crimper tool (usually with the flap pointed downwards), and tightly squeezing the handles together. 8. Complete steps 1-7 for the other side of the cable "Connector B". 9. Use a cable tester to test if your connections are correct. |
