  2. What is difference between POE and POE+
  3. Which was the primary requirement that converted POE into IEEE standard?
  4. What is IEEE standard for POE?
  5. What’s the IEEE standard for PoE+?
  6. What is difference between POE+ and UPOE?
  7. When was the IEEE 802.3at PoE+ standard ratified?
  8. What’s the maximum power delivered at the Powered Device (PD) according to the IEEE 802.3af PoE standard?
  9. What’s the maximum power delivered at the Powered Device (PD) according to the IEEE 802.3at PoE+ standard?
  10. What’s the maximum cable length used to connect Powered Devices (PD) to Power Sourcing Equipment (PSE)?
  11. Can I connect non-PoE devices to the PoE switch’s ports?
  12. What is the difference between inline power and PoE?
  13. What is the difference between the Cisco original PoE products and the IEEE 802.3af standard?
  14. What IP phone models support the Cisco pre-standard method of powered device detection?
  15. A Catalyst 3560 switch with 48 ports supports 370W. Because C7941G-GE is a Class 3 device, it requires up to 15.4W. Can this be reduced to 7W so that the switch can power all 48 phones?
  16. What is PSE?
  17. What is PD?
  18. A POE switch is powering 1st The 1st PD has further got another port daisy chained to 2nd PD. Can the 2nd PD get the POE power from POE Switch?
  19. While configuring POE on one of POE enabled Switch, which command will allow auto-detection of a PD and PoE auto-allocation?
  20. What command needs to be issued to verify the inline power configuration on Gigabit Ethernet port 2/5?
  21. What is FLP?
  22. A POE switch port is connected to a laptop .What happens to FLP when switch sends the FLP signal towards it?
  23. Which protocol or feature is responsible for adjusting power level on a Cisco Switch for a Cisco powered device?
  24. What are the different types of 802.3af power class?
  25. LED on port of POE switch is blinking amber color. What does that signify?
  26. What is the difference between inline power and PoE?
  27. A Cisco Catalyst POE 3560 switch with 48 ports supports 370W. A new IP phone is connected to it which requires up to 15.4W. Can this be reduced to 7W so that the switch can power all 48 phones?
  28. What are the Power management modes for POE switch?
  29. A catalyst Switch C2960X-48FPD-L is installed in customer Hub office. While installing 40 IP cameras (which work on POE+), not more than 12 IP cameras are working simultaneously. What could be the cause?
  30. Which command is used to display the power consumption data of POE catalyst switch?
