Switch devices are considered one of the most commonly used devices in different places, either commercial places or homes. Switch can connect different devices inside the loçal network to each other, and facilitate data transfer between them. Switch PoE devices can add an additional advantage, as it can provide power to the connected devices, without the need to use a lot of cables for direct connection to the power source. So what a PoE switch is? And how does it work? And what are the additional advantages it can add? That's what we are going to know in this article.
What is Swatch PoE and how does this switch work?
What is switch PoE? You may be asking about this type of switch, and here we will give you the answers. switch PoE is a type of switches which can provide electric power to the connected devices via ethernet cables. This means that this switch can provide electric power to the connected devices via network cables which means decreasing the need for additional cables for providing electric power to the connected devices.
PoE switches work via sending electric power through network cables this can occur through the using the unused cables in data transfer to provide electric power, or to use cables in sending both electric power and data to the connected devices. This means that the devices connected to the switch do not need a separate electrical power source, which makes this switch very distinctive, and capable of providing a number of additional features for the devices connected to it.
What are the advantages of using a PoE switch?
POS which you can provide a lot of advantages more than other switches as follows:
- Saving cables: as the connected devices can easily get power supply through this switch, without the need for an additional power source, it can save the use of the cables.
- Ease of installing various devices regardless of the location of the electrical power source: as PoE switch devices have the ability to provide power to connected devices easily, as the switch can be used to easily deliver electrical power to wireless devices in places where electrical current cannot easily be reached.
- Saving costs: PoE switches can help in saving electrical power easily and saving the cost of electrical cables connected to the switch.
- Central management of energy: as PoE switches can facilitate central management of the energy that reaches to every connected device which can ease the process of disconnecting or turning on power from connected devices.
- Ease of maintenance and replacement: in case of any malfunction or problem with the connected devices it can be easily fixed without having to change the power supply.
What are the devices that can be connected into the PoE switch?
PoE switches can match with a lot of devices these devices are follows:
- Various cameras that are used for security systems. Telephones that are used for calling via the internet, which support the VoIP protocol.
- Smart home systems, such as smart door control systems and smart lighting systems.
- wireless access points.
From what we have mentioned we can realize that PoE switches can be easily used with various devices to provide electric power supply to them.
What is the amount of electric power supply that can be provided by PoE switches?
PoE switches can provide an amount of energy that varies according to the supported standards by the switch. Different types of switches can support a number of standards as follows:
- IEEE 802.3af PoE standard, which provides 15.4W per port. It can provide 12.95W deliverable power to the connected device, so this type of switches can be used in low power devices.
- IEEE 802.3at PoE+ standard, which provides 30 watts per port. It can provide 25.5 watts to connected devices as a deliverable power. This type of switches are used for devices that require more power.
- The IEEE 802.3bt PoE++ standard, which is divided into two types: Type 3, which provides 60 watts of power per port, and deliverable power to the connected device measures 51 watts, and Type 4, which provides 100 watts of power per port and a deliverable power to the connected devices measures 90W. This type of switches are used for high-power devices.
We have mentioned what a PoE switch is? and what is the mechanism of its working? PoE switches can provide a solution to a lot of problems regarding power supply connection, which can help in saving the used cables, provide an easy management to the connected devices in addition to a number of benefits that make this switch perfect to the crowded environments.
