Using PoE Clocks on an Existing Network

Have you ever finished a building project and realized that one component was overlooked? Have you ever been in a situation when the building owner has approached you after the completion of his or her building and asked you to install one more system or device? As a new building or infrastructure goes up, architects and engineers will commonly be faced with one of these situations. For example, the owner wanted a different kind of phone or lighting system installed. Or maybe at the end of the project, you’ve looked back and realized the building was specified to have synchronized time displays, but they were never installed.

In approaching this kind problem, the key is this: knowing the right systems for this situation. When it’s the clocks that are overlooked or a last minute addition to the new infrastructure, architects and engineers can turn to the PoE clock for a solution. PoE clocks work great in this situation because they can function on a facility’s existing infrastructure, meaning the clocks can use the Ethernet network that was installed in the building during its creation in order to operate—allowing the clocks to be installed without breaking through the walls and running more wiring.

So what exactly has to happen in order for PoE clocks to be installed in the building after its completion? Say the owner requires synchronized digital time displays in his or her office, as well as 15 other offices and five hallways in the building. Supplies purchased for this type of installation will be 21 PoE digital clocks, about 100 ft of Ethernet cabling and 21 PoE injectors.

What is the PoE injector? This is what makes the technology of Power over Ethernet possible, without having to run wiring throughout the building. The injector takes power from an outlet and time data from an Ethernet connection and combines the two into one output—one Ethernet cable that goes straight to the clock. This one connection to the clock will provide it with the power to light up its display as well as the time data it needs to synchronize with all the other clocks in the system.

After the installation of 21 PoE clocks using 21 PoE injectors and the necessary Ethernet cabling, the building will be equipped with the synchronized time displays that were not installed during the construction of the building. This gives the architect or the engineer a solution when something like the synchronized clock system goes overlooked, or the owner makes a last minute decision. No matter what the situation is, when a new building project requires the installation of synchronized time after its completion, the PoE clock is perfect for using existing infrastructure and avoiding the extra time and cost associated with running wiring.
