RJ45 keystone jacks are commonly used in networking applications to provide connectivity to Ethernet cables. These jacks are designed to fit into a keystone wall plate or patch panel, allowing for clean and organized cable management. In this article, we will guide you through the process of connecting an RJ45 keystone jack.

Step 1: Gather Your Tools and Materials

To connect an RJ45 keystone jack, you will need the following tools and materials:

- RJ45 keystone jack

- Ethernet cable

- Wire stripper

- Cable cutter

- Punchdown tool

Step 2: Strip the Ethernet Cable

Using the wire stripper, remove roughly 1 inch of the outer jacket from the Ethernet cable. Be careful not to damage the inner wires.

Step 3: Prepare the Wires

Untwist the four pairs of wires within the Ethernet cable. Sort the wires according to the following color codes:

- Pin 1: White with Orange Stripe

- Pin 2: Orange

- Pin 3: White with Green Stripe

- Pin 4: Blue

- Pin 5: White with Blue Stripe

- Pin 6: Green

- Pin 7: White with Brown Stripe

- Pin 8: Brown

Step 4: Insert the Wires into the Keystone Jack

Insert the wires into the corresponding color-coded slots on the keystone jack. Be sure to align the wires properly, so that each wire is fully inserted into the appropriate slot.

Step 5: Punch Down the Wires

Using a punchdown tool, firmly press each wire into place on the keystone jack. This will secure the wires and ensure optimal connectivity.

Step 6: Trim the Wires

Using a cable cutter, trim the excess wires from the keystone jack. This will help to ensure that the jack fits neatly into the keystone wall plate or patch panel.

Step 7: Install the Keystone Jack

Insert the keystone jack into the keystone wall plate or patch panel. Press firmly until the jack clicks into place.


Connecting an RJ45 keystone jack requires careful attention to detail, but the end result is a reliable and organized network connection. By following these simple steps, you can easily connect your keystone jack and enjoy fast and stable Ethernet connectivity.
