Power over Ethernet

In this section:

  1. Power over Ethernet Overview
  2. Auto-Enabling of PoE
  3. Support for PoE Legacy Power-Consuming Devices
  4. Enabling the Detection of PoE Power Requirements Advertised Through CDP
  5. Setting the Maximum Power Level for a PoE Power-Consuming Device
  6. Setting the Power Class for a PoE Power-Consuming Device
  7. Setting the Inline Power Priority for a PoE Port
  8. Resetting PoE Parameters
  9. Inline Power on PoE LAG Ports
    Inline power on Power over Ethernet (PoE) LAG ports is enabled by default.
  10. Fanless Mode Support
    Fanless mode enables the device to operate with the fans disabled while limiting the PoE budget to 150 Watts. That is, when fanless mode is enabled, the fan speed is set to zero RPM, thus allowing the device to operate silently.
  11. Automatic Fanless Mode Support for RUCKUS AV 8200 Switch
    RUCKUS AV Switches employ intelligent fan management systems to optimize cooling efficiency. During the boot process or after a reload, fans may operate at a higher speed to ensure adequate cooling. Once the system stabilizes, fan speeds are adjusted based on internal temperature sensors. This dynamic approach ensures optimal cooling performance without unnecessary noise.
