PropertyDescription
print ()Prints PoE-Out related settings.
export ()export is displayed under /interface ethernet menu.
monitor (string| interface)Shows poe-out-status of a specified port, or all ports with /interface ethernet poe monitor [find] command.
power-cycle (duration:0..1m |; Default: 5s)Disables PoE-Out power for a specified period of time.

Global Settings

Some MikroTik PoE-Out devices support the global PoE setting which can be configured under /interface ethernet poe settings menu. 

PropertyDescription
ether1-poe-in-long-cable (yes | no)Setting it to "yes" will disable short detection on all poe-out ports. This is potentially dangerous settings and should be used with caution

Global setting ether1-poe-in-long-cable feature disables strict input/output current monitoring (short detection) to allow the use of PoE-Out with long ethernet cables and/or avoiding improper short-circuit detection.

...

Info

Note: Global setting of ether1-poe-in-long-cable 

...

can also affect PoE-Out behavior on PSE which is powered using a DC connector


PropertyDescription

psuX-max-power


Specifies the maximum power in watts that the PSU can draw.  default - 96W

psu1 - DC-jack

psu2 - 2-PIN terminal

This command is designed specifically for RB5009UPr+S+IN to ensure the safety and optimal performance of the Power Supply Unit (PSU). It allows users to set the maximum power limit for the PSU, preventing potential overload that could compromise the stability and longevity of the system. 

...

Port Settings

PoE-Out can be configured under the menu. Each port can be controlled independently.


PropertyDescription
name ()Name of an interface
poe-out (auto-on | forced-on | off; Default: auto-on)Specifies PoE-Out state
  • auto-on - the board will attempt to detect if power can be applied to the port. For powering there should be resistance in the range from 3kΩ to 26.5kΩ
  • forced-on - detection range is removed. As a result power over Ethernet will be always on
  • off - all detection and power is turned off for this port
poe-priority (integer:0..99 | any; Default: 10)poe-priority specifies the importance of PoE-Out ports, in cases when a total PoE-Out limit is reached, interface with the lowest port priority will be powered off first.

Highest priority is 0, the lowest priority is 99. If there are 2 or more ports with the same priority then port with the smallest port number will have a higher priority. For example, if ether2 and ether3 have the same priority and over-current is detected then PoE-Out on ether3 will be turned off.

Every 6 seconds ports will be checked for a possibility to provide PoE-Out if it was turned off due to port priority.
poe-voltage (auto | low | high; Default: auto)

A feature that allows us to manually switch between two voltage outputs on PoE-Out ports. It will take effect only on PSE with switchable voltage modes (CRS112-8P-4S-IN, CRS328-24P-4S+RM, netPower 16P, CRS354-48P-4S+2Q+RM).

poe-lldp-enabled ( yes / no; Default: no)

Link Layer Discovery Protocol (LLDP) is a layer-2 Ethernet protocol for managing devices. LLDP allows an exchange of information between a PSE and a PD. 

Starting from RouterOS version 7.15, the setting has been replaced with the Neighbor Discovery lldp-poe-power property.


Info

Note: Enabling poe-lldp in RouterOS 7.8 can potentially solve issues encountered in VoIP setups.

...

Info

Note: If poe-voltage=auto and poe-out is set to "forced-on", LOW voltage will be used by default. If the PD supports only high voltage, make sure you also set poe-voltage=high when forcing the PoE output.

 

Power-cycle settings

RouterOS provides a possibility to monitor PD using a ping, and power-cycle a PoE-Out port when the host does not respond. power-cycle-ping feature can be enabled under /interface ethernet poe menu.

...

PropertyDescription
name ()Name of an interface
poe-out ()Shows PoE-Out settings
poe-out-status ()Shows current PoE-Out status on port
  • powered-on - Power is applied to the port, and PoE-Out is operating normally,
  • waiting-for-load - PSE attempts to detect if power can be applied to the port. For powering there should be resistance in the range from 3kΩ to 26.5kΩ;
  • short-circuit - Short-circuit is detected on PoE-Out port, power is switched off, the only detection with low voltage takes place.
  • overload - The PoE-Out current limit is exceeded, power is switched off on PoE-Out port. For port limits see each model specifications.
  • voltage-too-low - PD can not be powered with the voltage provided from PSE.- PD can not be powered with the voltage provided from PSE.
  • voltage_too_high - PSE controller cannot power PD with high voltage;
  • current-too-low - current-too-low means that PD draws too low current  (<10mA) than normal PoE-Out device should, the reason for this can be:

The delivered voltage at PD is too low for normal powering (for example Vmin =>30V, but provided 24V);

PD uses a second power source which has a higher voltage than PSE, so all current is taken from the second DC source, not PSE PoE-Out port;

  • off - all detection and power is turned off for this port;
  • power_reset - PSE controller resetting the power, for example, when executing the power cycle command or when pings fail (power-cycle-ping);
  • controller_init - PSE controller initialization;
  • controller_upgrade - PSE controller is being upgraded;
  • controller_error - PSE controller does not respond.
poe-out-voltage ()Displays PoE Voltage which is applied to the PD.
poe-out-current ()Displays port current (mA) which is drawn by the PD.
poe-out-power ()Displays PD power consumption
