PoE+ Switches

Power-over-Ethernet switches are products that enable communication between the devices in a network by using Power-over-Ethernet (PoE) PSE (Power Sourcing Equipment) technology. These switches feature a built-in PoE junction for power management and data transmission simultaneously over a twisted-pair cable. The PoE network switches with SFP modules can be used for dual transmission over a fiber optic cable as well. VERSITRON manufactures PoE+ switches in both commercial and industrial formats. These switches comply with the IEEE802.3at-2009 PoE standard and support a power consumption of up to 30 watts per port. This wattage is sufficient to power network devices such as security cameras, wireless access points, and VoIP phones. All devices are managed with port sizes ranging from 4 up to 52 ports.

What is a PoE+ Switch?

A PoE+ switch is an advanced version of Power over Ethernet (PoE) Technology that complies with the IEEE802.3at standard. These switches supply power over two pairs of cables and provide 30 watts of power per port whereas a standard PoE switch only provides 15.4 watts per port. These switches are used to connect certain networking devices, which may require more source power such as IP cameras and VoIP Phones. Powered (PD) devices are supported in the operating voltage range between 50V to 57V. PoE+ Switches also offer advanced features like QoS, VLAN, and security protocols to manage and optimize network traffic.

PoE+ switches are designed to be backward compatible with PoE devices, so they can also power devices that are compatible with the original PoE standard. However, devices that require more than 15.4 watts of power will only function properly when connected to a PoE+ switch.

What are the Components of PoE Switches?

The PoE network switch enables the data transmission between a data source to the receiver equipment. However, the power function of these switches relies on the following components of the PoE system:

  • Power Sourcing Equipment (PSE):

    The power transmission in a PoE system takes place between a power source and a powered device (PD). The source of power that transmits power to the Ethernet cable is referred to as power sourcing equipment (PSE).
    PSE can be connected to powered devices (PD) in one of the following two ways.
    • ENDSPAN:

      ENDSPAN is the PoE transmission where there is absolutely no need for an additional power supply from PSE to PD.
    • MIDSPAN:

      MIDSPAN is the PoE transmission where an additional power supply is integrated at the mid-length of the transmission cable. Commonly, PoE injectors are used as MIDSPAN power supply in the PoE systems.
  • Powered Device (PD):

    The device that consumes the power transmitted by Ethernet cable is known as a powered device (PD). There can be one or multiple powered devices (PDs) in the PoE system. The powered devices can be VoIP phones, IP cameras, wireless access points, network terminals, etc.
  • Ethernet Cable:

    Ethernet cable is the intermediate bidirectional transmission media between the PSE and PDs. The Ethernet cable can be a twisted-pair copper cat5 or cat6 cable. It enables the transmission of data and power simultaneously.
  • Management Interface:

    This is used to configure and manage the switch, including setting up VLANs, monitoring network traffic, and configuring QoS settings.
  • Cooling System:

    This keeps the switch cool to prevent overheating and ensure reliable operation.

How does a PoE Switch work?

A PoE switch configuration is easy to understand, owing to its simple construction. The Power over Ethernet switch features several Ethernet ports to ensure that power is provided to the networking devices connected to it. These switches may be operated in any of the following configurations:

  • Mode A Configuration: In this configuration, the switch delivers power and data through the same wire.
  • Mode B Configuration: In this configuration, the switch delivers power and data through different wires.

What are the Features and Specifications of PoE/PoE+ Switches?

PoE/PoE+ switches are gaining in popularity over other types of devices because they help simplify the installation and complex layouts in expanding networks. Their ability to transmit data and power devices over a single cable makes them more suitable than other types of switches. VERSITRON’s Gigabit PoE Ethernet switches are distinguishable due to the following features:

  • Our high-end managed gigabit Ethernet switches (10/100/1000) can transmit Ethernet, Fast Ethernet, and Gigabit Ethernet transmissions effectively.
    • Ethernet: Our industrial switches offer a 10 Mbps transmission rate.
    • Fast Ethernet: Our Fast Fiber and Ethernet switches can transmit a data rate of 100Mbps.
    • Gigabit Ethernet: The Gigabit Ethernet switches assure a 1000 Mbps data transmission rate.
  • Our standard PoE Ethernet switches are compatible with Cat5e and Cat6 twisted-pair cables
  • Our SFP-integrated Gigabit PoE+ switches are compatible with singlemode, multimode, simplex, or duplex types of fiber optic transmission.
  • PoE or PoE+ switches offer better adaptability since this equipment can be transferred to any remote location without an active source of power supply.
  • The PoE and PoE+ switches feature copper-fiber compatibility with built-in SFP ports which makes them suitable for hybrid Ethernet networks.
  • • Jumbo frame transmission is supported which enables the transmission of bulky data files.
  • The port mirroring or switched port analyzer (SPAN) feature of these PoE switches allows the replication of data packets sent to different devices over a VLAN network.
  • Virtual stacking management (VSM) feature in our PoE switches enables centralized management, monitoring, and control over functions of multiple switches in a network.
  • Our switches support STP and RSTP protocols which improves their port capabilities such as discarding and forwarding data packets.
  • The PoE powered network switches encourage multicast VLAN registration (Port-based and 802.1Q tag-based LAN)
  • Our PoE network switches support spanning tree protocol which prevents data loops in case of redundant paths in the network.
  • Link aggregation control protocol (LACP) supported by VERSITRON’s PoE switches allows establishing an LACP data unit connection between two devices in a network.
  • We offer full-time support and maintenance to the customers, therefore, maintenance and troubleshooting are no hassle for our customers.
