What is PoE?
Power over Ethernet (PoE) is a revolutionary technology that allows both power and data to be transmitted over standard Ethernet cables. In the context of the Internet of Things (IoT), this means that IoT devices can be powered and connected to the network using a single cable, simplifying installation and reducing clutter.
PoE Issues on MFP Network Connections
While PoE offers numerous advantages, it can also lead to significant issues, especially with Multi-Function Printers (MFPs) and other networked printers. These devices may “lock up,” exhibit random SC codes, or suffer damage to critical components such as the network interface card, hard drive, and motherboard.
Why is This Urgent
The urgency of addressing PoE issues stems from several factors:
- Increasing PoE Switch Installations: More PoE switches are being installed with minimal configuration, leading to potential problems.
- Unintentional Use of PoE Ports: Staff may unknowingly use PoE ports for devices that are not designed to handle PoE.
- Irreversible Damage: Damage caused by improper PoE usage is often irreversible and can void warranties.
Prevention Tips
To prevent these issues, consider the following tips
- Disable PoE on Printer/Copier Ports: Ensure that PoE is disabled on ports used for printers and copiers.
- Label Ports as ‘No PoE’: Clearly label ports that should not be used for PoE to avoid accidental usage.
- Train IT and Field Staff: Provide appropriate training to IT and field staff to ensure they understand the risks and proper usage of PoE.
By taking these preventive measures, you can safeguard your networked devices and ensure smooth operation without the risk of damage from PoE.
