The Bisset Brief: Label those Cables!

Posted by John Bisset on Aug 9, 2017 11:15:00 AM

As I travel throughout the US, I've seen a number of great Axia Livewire+ AES67 AoIP installations, and enjoy sharing some of these concepts with readers.

IP Audio Networking and clearing out analog wiring has been a key theme of late. Clearing unneeded cabling is an essential concern when converting to Livewire+ AES67, and it's crucial to label your Axia Livewire+ AES67 CAT5/6 cabling. Over time, networks grow, and labeling your Ethernet cables ensures the wiring won’t get out of hand.

With this in mind, E. W. Scripps Tucson engineers Derek Batterham, Ryan Oler, and Edward Hernandez demonstrate their Axia wiring handiwork on their Cisco Ethernet switch in Figure 1, below.

Figure 2 below shows their use of a Brady Labeling Machine with labels on each end of the cable.

For those not familiar with this device, the actual label has a printed portion (for cable identification), and a length of clear tape. The clear tape wraps around the printed portion, protecting the label. This kind of labeling is good insurance, since your network is going to be around for a long time. Once things are labeled, engineers have an organized way to route the network Ethernet cables.

On a related note, brush panels make for a neat way to cover wire openings to your switch or patch panel. The brush bristles permit ethernet cables to pass through, but keep airflow for cooling inside the rack. The bristles also keep the cabling neat and orderly. Julio Alvarado, Cumulus Tucson Engineering Manager, recommends the brush panels from Middle Atlantic, model BR1 (see figure 3, below).

Middle Atlantic has combined a slotted rack panel with a multitude of fine flexible plastic fibers covering the opening. When needed, the fibers can be physically moved aside, to permit an Ethernet (or other) cable to pass through (as seen in figure 4).
