Networking, Power over Ethernet
Power over Ethernet
Power over Ethernet (PoE) is a technology that allows applicable network-connected devices to be powered via their connection to the network switch, instead of with their own AC adapter. Using Power over Ethernet can make deploying devices easier, allows devices to be power cycled remotely, and can be more energy efficient.
In the past, Technology Services has not been able to provide PoE to the campus due to the limited equipment and power available. However, Technology Services Networking has made significant upgrades to the Campus Network and is now able to offer full PoE on the majority of Network equipment on Campus.
Guidelines for Power over Ethernet on campus
Power over Ethernet is available to IT Pros on Technology Services managed network switches with the following guidelines.
- Power over Ethernet is provided on a best-effort basis, depending on the power and equipment that are available. Infrequently, there may not be enough available power or equipment to provide PoE. If there is not enough power available on a switch, PoE may be disabled for Departmental PoE devices.
- Priority for Power over Ethernet will be given to Technology Services devices which support critical services, such as wireless access points and security cameras. If the switch does not have enough available power, PoE to other devices may be disabled in order to provide enough power to critical devices.
- Technology Services may disable Power over Ethernet in situations where a device is causing adverse effects to the network or to other devices.
- If you would like to use PoE on a type of device that will require more than 17W of power, please contact Technology Services Networking so that we can verify that enough power is available.
Configuring Power over Ethernet
Power over Ethernet can be managed by IT Pros using the Technology Services Iris tool. Instructions for using Iris can be found on the Iris service details page.
Checking the "PoE" checkbox will enable PoE for the port. Unchecking the PoE checkbox will disable PoE for the port. The PoE field will have a green background when PoE is enabled and currently being delivered to the port, and a white background when PoE is not being delivered.
