110 Patch Panel: How To Punch Down

The 110 voice patch panel is a commonly used voice patching tool in data center projects. Next, we'll walk through how to punch down the 110 patch panel, using a 25-pair cable as an example.

110 Voice Patch Panel

 

(1) Secure the 110 patch panel to the appropriate position in the cabinet.

(2) Start by organizing the cables from where they enter the cabinet. Route the cables along both sides of the network cabinet to the patch panel, leaving approximately 25 centimeters of the large-pair cable. Use a cable crimper or wire stripper to remove the outer sheath of the large-pair cable (as shown in Figure 1). Secure the cables with cable ties, pass the cables through the entry holes on one side of the 110 voice patch panel, and arrange them at the punch-down area of the patch panel (as shown in Figure 2).

(3) Organize the 25-pair cables in the correct sequence. First, allocate the major colors (as shown in Figure 5-48), then allocate the minor colors (as shown in Figure 5-49). The standard allocation principle is as follows: Communication cable color code arrangement: Major colors of the cables are: white, red, black, yellow, purple. Minor colors of the cables are: blue, orange, green, brown, gray. A group of cables consists of 25 pairs, grouped by color bands, totaling 25 groups as follows:

① (white-blue, white-orange, white-green, white-brown, white-gray)

② (red-blue, red-orange, red-green, red-brown, red-gray)

③ (black-blue, black-orange, black-green, black-brown, black-gray)

④ (yellow-blue, yellow-orange, yellow-green, yellow-brown, yellow-gray)

⑤ (purple-blue, purple-orange, purple-green, purple-brown, purple-gray).

Pairs 1-25 form the first subgroup, wrapped with a white-and-blue striped band. Pairs 26-50 form the second subgroup, wrapped with a white-and-orange striped band. Pairs 51-75 form the third subgroup, wrapped with a white-and-green striped band. Pairs 76-100 form the fourth subgroup, wrapped with a white-and-brown striped band. These 100 pairs make up a major group, which is then wrapped together with a white-and-blue striped band. Groups of 200, 300, 400, ..., up to 2400 pairs follow the same pattern. The grouping effect is shown in Figures 3 and 4.

(4) According to the cable color code arrangement, carefully press each color-coded pair into the slots one by one (as shown in Figure 5), then use a 110punch-down toolto secure the wire connections, and trim any excess wire that extends beyond the slots. Note: The blade should be perpendicular to the patch panel, with the blade edge facing outward, as shown in Figure 6.

(5) Gather a 5-pair punch-down tool and the necessary 110 connecting blocks (as shown in Figure 7). Insert the 110 connecting blocks into the 5-pair punch-down tool (as shown in Figure 8), and press the 110 connecting blocks vertically into the slots (as shown in Figure 9). Don't forget to attach numbered labels for easy identification. Note the combination of connecting terminals: When installing on a 25-pair 110 patch panel base, choose either 5 four-pair 110 connecting blocks and 1 five-pair 110 connecting block, or 7 three-pair 110 connecting blocks and 1 four-pair 110 connecting block. Complete the installation from left to right, following the white, red, black, yellow, and purple zones. This is consistent with the installation color sequence of the 25-pair cable. The final result is illustrated in Figure 10.
