Achieve Better Power Efficiency with Insights into PoE Usage

Summary

In this Cisco Catalyst Center training video, Krishna Diwakar explores Power over Ethernet (PoE), highlighting its ability to power devices like cameras and access points through standard Ethernet cables, enhancing flexibility and efficiency in network installations. The video delves into PoE's challenges, such as power budgeting and device compatibility, and introduces the Catalyst Center's intuitive PoE dashboard. This dashboard simplifies PoE management, aids in fault detection, and supports sustainability goals by estimating power savings from access points in power save mode. Viewers are guided through the dashboard's features, including monitoring power usage, identifying free PoE ports, and understanding PoE device distribution across the network.

Takeaways

• 🔌 PoE (Power over Ethernet) is a game-changing technology that powers devices like cameras and access points through the same Ethernet cables used for data transmission.
• 🔄 PoE offers flexibility and efficiency in network installations by eliminating the need for separate power sources and connections for each device.
• 🔋 The power budgeting in PoE is crucial as switches have a limited amount of power they can supply, and different devices require different power levels.
• 🔍 Device compatibility with PoE is essential to ensure that the switch can deliver the necessary power without exceeding its limits.
• 🚨 Fault detection in PoE is important for quickly identifying issues like power outages or devices drawing excess power, allowing for proactive measures.
• 📊 The Catalyst Center's PoE dashboard simplifies management by providing information on power usage, available PoE ports, power distribution, and operational state.
• 🌿 The Catalyst Center supports sustainability goals by estimating power savings when access points are run in power save mode.
• 🖥️ To access the PoE dashboard, log into the Catalyst Center, navigate through the Assurance menu, and select PoE.
• 📈 The dashboard includes various dashlets that provide insights into PoE devices and switches, including the number of devices, power allocation, and device status.
• 🔗 The dashboard allows for detailed device information, such as type, connected switch, and power allocation, with options to take action on specific ports.
• 📊 The power distribution dashlet shows how power is allocated across PoE devices, and the PoE Insights dashlet provides information on device types and their capabilities.
• 🔌 The dashboard helps administrators identify free PoE ports and switches capable of providing the required power for new devices.
• 💡 Dashlets also assist in tracking sustainability efforts, such as the number of APs that can run in power-saving mode and the power saved as a result.
