Keystone jacks are commonly used in network installations for connecting Ethernet cables. They are small, rectangular connectors that are installed in a wall plate or patch panel. A keystone jack wiring diagram is a visual representation of how to wire a keystone jack. In this guide, we will take a closer look at keystone jack wiring diagrams and how to use them.
What is a Keystone Jack Wiring Diagram?
A keystone jack wiring diagram is a schematic diagram that shows the correct wiring configuration for a specific type of keystone jack. It provides a visual representation of the wiring sequence that is required to properly connect Ethernet cables to the jack. These diagrams are commonly used by installers and technicians to ensure that the wiring is correct and to troubleshoot any problems that may arise.
Why is a Keystone Jack Wiring Diagram Important?
A keystone jack wiring diagram is important for several reasons. Firstly, it ensures that the wiring is correct and that the connection will work as expected. If the wiring is incorrect, the connection may not work or may work poorly, resulting in slow data transfer speeds, dropped connections, or intermittent connectivity. Secondly, a wiring diagram allows you to troubleshoot any issues that may arise with the connection. By referring to the diagram, you can identify any wiring errors and correct them quickly and easily.
Where Can I Find a Keystone Jack Wiring Diagram?
A keystone jack wiring diagram can usually be found on the packaging or documentation that comes with the keystone jack. If you do not have access to these materials, you can usually find wiring diagrams online by searching for the specific type of keystone jack that you are using. Some manufacturers also provide wiring diagrams on their websites.
What Tools Do I Need for Wiring a Keystone Jack?
Before you begin wiring a keystone jack, you will need the following tools:
- Cat5e or Cat6 Ethernet cable
- Keystone jack
- 110 punchdown tool
- Cable stripper
- Cable tester
These tools are essential for ensuring that the wiring is done correctly and that the connection works as expected.
How to Wire a Keystone Jack
Wiring a keystone jack is a straightforward process that requires a few simple steps. Follow these steps to wire a keystone jack:
Step 1
Strip about 1 inch of the outer sheath from the Ethernet cable using a cable stripper. Be careful not to nick the wires inside the cable.
Step 2
Untwist the pairs of wires and separate them. Arrange the wires according to the T568A or T568B wiring standard, depending on which one you are using.
Step 3
Insert the wires into the slots on the keystone jack. Be sure to follow the wiring diagram for the specific type of keystone jack you are using.
Step 4
Use a 110 punchdown tool to punch down each wire onto the keystone jack. This ensures a secure connection and good contact between the wire and the jack.
Step 5
Trim any excess wire using wire cutters.
Step 6
Insert the keystone jack into a wall plate or patch panel.
Step 7
Test the connection using a cable tester to ensure that it is working properly.
Keystone Jack Wiring Standards
There are two commonly used wiring standards for Ethernet cables: T568A and T568B. These standards specify the order in which the wires should be arranged and connected to a keystone jack. Here is a breakdown of each standard:
T568A Wiring Standard
| Wire Color | Pin Number |
|---|---|
| Green/White | 1 |
| Green | 2 |
| Orange/White | 3 |
| Blue | 4 |
| Blue/White | 5 |
| Orange | 6 |
| Brown/White | 7 |
| Brown | 8 |
T568B Wiring Standard
| Wire Color | Pin Number |
|---|---|
| Orange/White | 1 |
| Orange | 2 |
| Green/White | 3 |
| Blue | 4 |
| Blue/White | 5 |
| Green | 6 |
| Brown/White | 7 |
| Brown | 8 |
The T568B wiring standard is more commonly used in the United States, while the T568A wiring standard is more commonly used internationally. Either standard can be used as long as it is consistent throughout the network installation.
