PoE

Power over Ethernet (PoE) describes any system that passes electric power along with data on twisted pair Ethernet cabling. Doing this allows a single cable to provide both data connection and electric power to devices (for example, wireless access points, IP cameras, and VoIP phones).

PoE is only available on models with the POE suffix in the model number (for example, FS-108E-POE).

 

Using the GUI:
  1. Go to Switch > POE.

  2. Set the PoE power mode to priority based or first-come, first-served.

    When power to PoE ports is allocated by priority, lower numbered ports have higher priority so that port 1 has the highest priority. When more power is needed than is available, higher numbered ports are disabled first.

    When power to PoE ports is allocated by first-come, first-served (FCFS), connected PoE devices receive power, but new devices do not receive power if there is not enough power.

    If both priority power allocation and FCFS power allocation are selected, the physical port setting takes precedence over the global setting.

  3. Enable or disable PoE pre-standard detection.

    PoE pre-standard detection is a global setting for the following FortiSwitch models:

    FSR-112D-POE, FS-548D-FPOE, FS-524D-FPOE, FS-108D-POE, FS-224D-POE, FS-108E-POE, FS-108E-FPOE, FS-124E-POE, and FS-124E-FPOE.

    For the other FortiSwitch PoE models, PoE pre-standard detection is set on each port.

  4. Set the maximum power budget in Watts.
  5. Enter the power in Watts to reserve in case of a spike in PoE consumption.
  6. Enter the threshold (a specified percentage of the total power budget) above which an alarm event is generated.
    If your FortiSwitch unit has a PoE sensor, you can set an alarm for when the current power budget exceeds a specified percentage of the total power budget. When this threshold is exceeded, log messages and SNMP traps are generated. The default threshold is 80 percent.
  7. Select Update.
Using the CLI:

config switch global

set poe-alarm-threshold <0-100 percent>

set poe-power-mode {first-come-first-serverved | priority}

set poe-guard-band <1-20 Watts>

set poe-pre-standard-detect {disable | enable}

set poe-power-budget <1-740 Watts>

end
