PoE-Out Configuration

PoE Configuration is supported on all MikroTik devices with PoE-Out interfaces, the configurations can be edited from the RouterOS and SwOS interfaces.

RouterOS

Usage

RouterOS provides an option to configure PoE-Out over Winbox, Webfig and CLI, basic commands using the CLI are

Global Settings

Some MikroTik PoE-Out devices support global PoE setting which can be configured under menu.
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.

Note: Global setting of ether1-poe-in-long-cable can also affect PoE-Out behaviour on PSE which is powered using a DC connector

Port Settings

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

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 menu.

• PoE Out — Change between modes (auto/on/off)
• PoE Priority — Change the of port (0…8)
• Voltage Level — Change between two voltage outputs on PoE-Out ports (auto/low/high)

PoE-Out Monitoring

RouterOS

MikroTik devices with PoE-Out controller (not injector) provides port monitoring option.

If feature is used, will show additional fields:

power-cycle-host-alive: <YES/NO> (Shows if monitored host is reachable)
power-cycle-after:<TIME> (Shows time, after which the port will be power-cycled)

SNMP

SNMP OID tables:

• 1.3.6.1.4.1.14988.1.1.15.1.1.1 — interface id
• 1.3.6.1.4.1.14988.1.1.15.1.1.2 — interface names
• 1.3.6.1.4.1.14988.1.1.15.1.1.4 — voltage in dV (decivolt)
• 1.3.6.1.4.1.14988.1.1.15.1.1.5 — current in mA
• 1.3.6.1.4.1.14988.1.1.15.1.1.6 — power usage in dW (deviwatt)

SNMP values can be requested also from the RouterOS, for example, will print current mA from all available PoE-Out ports:

/tool snmp-walk address=10.155.149.252 oid=1.3.6.1.4.1.14988.1.1.15.1.1.5

To get very specific OID value, use tool (displays current mA on ether3 interface):

tool snmp-get address=10.155.149.252 oid=1.3.6.1.4.1.14988.1.1.15.1.1.5.3

SwOS

A PoE-Out controller will enable certain monitoring features also from SwOS, such as PoE-Out Status, PoE-Out Current, PoE-Out Voltage and PoE-Out Power usage.

All PoE-Out configuration and monitoring is located on one page, under PoE tab :

Troubleshooting

In cases where a PD does not power-up or reboots unexpectedly when powered from your PSE, it’s suggested to first check:

• PD supported input voltage — PSE output voltage must be in the range supported by the PD. Otherwise the PD is incompatible with the PSE, and will not be able to power-up. Check the PD datasheet.
• PD supported input PoE-in standard — Some PDs do not support af/at standard even if it has PoE-in support up to 57 V, check PD datasheet.
• PD is rebooted from PSE
  • Check if PD does not exceed PoE-Out port limit and Total-PoE-Out port limit of the PSE, check PSE datasheet.
  • Check if Voltage limit does not drop bellow supported (Can be caused by voltage drop on the wires).
  • Check if you are using a proper power supply, the output power of PSU should be calculated from:

    (MAX power consumption of PSE) + (MAX power consumption of all PD) + 10%)

  • Check if you are using good quality ethernet cables, it’s important especially in cases if PoE is used.
• PD Does not power up
  • There can be cases where a PD does not power up, even though it supports passive PoE, and does not consume more power than the specified PSE port limit. This can be caused by inrush current triggering overcurrent protection on the PSE. Make sure that PD specification supports powering from PSE (not only from passive power injector)
  • Polarity — Devices with opposite or different pinout can be unable to powerup from all PSE. Check PD datasheet.
  • Incompatible resistance — PD resistance on spare pairs should have range from 3kΩ to 26.5kΩ (For Passive-PoE) and from 23.75kΩ to 26.25kΩ on af/at.

PoE Out examples

RouterOS allows to define priorities on PoE-Out ports, so if your installation is going over power budget, the PSE will disable less important PD with the lowest priority.

Priority of is the highest priority, 99 — lowest

Setting up priority

Example of how to set priorities from CLI:

 /interface ethernet poe set ether2 poe-priority=10
 /interface ethernet poe set ether3 poe-priority=13
 /interface ethernet poe set ether4 poe-priority=11
 /interface ethernet poe set ether5 poe-priority=14

What will happen when power budget will go over total PoE-Out limit — first, if overload is detected, ether5 will be turned off (lowest priority), then recheck is done and if still total limit overload is detected next port in priority will be turned off, in this example, ether3 will be turned off. Both of these ports will be reached every few seconds to check if it is possible to turn PoE-Out on for these ports. Power up will happen in reverse order as the power was cut.

Same priority

if all, or some ports will have the same poe-priority, then port with the lowest port number will have higher priority

 /interface ethernet poe set ether2 poe-priority=10
 /interface ethernet poe set ether3 poe-priority=10
 /interface ethernet poe set ether4 poe-priority=10
 /interface ethernet poe set ether5 poe-priority=10

In this example, if the total PoE-Out limit is reached ether5 will be turned off first, then ether4 then ether3 as all of these ports have same poe priority.

Monitoring PoE-Out

PoE-Out ports can be monitored using a command

 > interface ethernet poe monitor 
              name: ether2 ether3 ether4 ether5
   poe-out-voltage: 23.2V  23.2V  23.2V  
   poe-out-current: 224mA  116mA  64mA   
     poe-out-power: 5.1W   2.6W   1.4W 

Power-cycle ping

Monitor connected PD with power-cycle-ping feature:

/interface ethernet poe set ether1 power-cycle-ping-enabled=yes power-cycle-ping-address=192.168.88.10 power-cycle-ping-timeout=30s

In this example, PD attached to ether1 will be continuously monitored using a power-cycle-ping feature, which will send ICMP ping requests and wait for a reply. If PD with IP address 192.168.88.10 will not respond for more than 30s, the PoE-Out port will be switched off for 5s.

How it works

PoE-Out Modes

auto-on mode

If auto-on is selected on PoE-Out interface, then port operates in this strict order:

• PSE with low voltage checks for a resistance on the connected port. If detected resistance range is between (3kΩ to 26.5kΩ) power is turned on;
• When power is applied, the PSE continuously checks if overload limit is not reached or short circuit detected
• If the cable is unplugged, the port returns in detection state and will remain off until suitable PD is detected

forced-on mode

If forced-on is selected then port operates in this strict order:

• PSE disables resistance check on the port, and apply power on pins 4,5 (+) and 7,8 (-), even if no cable is attached
• When power is applied, PSE still continuously checks if an overload or short circuit is not detected
• After the cable is unplugged, the power still remains enabled on the port.

off mode

If off mode is used, PoE-Out on the port will be turned off, no detection will take place, and interface will behave as a simple Ethernet port.

PoE-Out limitations

It is important to check PoE-Out specification to find out hardware limitations because it can differ between models

PoE-Out port limitation

PoE-Out ports are limited with max amp values which are supported in particular voltage, usually max current will differ for low voltage devices (up to 30 V), and for high voltage devices (31 to 57 V).

PoE Out polarity

Note: Passive PD with high input inrush current can result in overcurrent protection on PSE, make sure that PD specification supports powering from PSE (not only from the passive power injector)

Safety

PSE has following safety features:

PoE-Out compatibility detection

The auto-on mode is considered safe, it will check if the resistance on the port is within allowed range and only then enable PoE out on the interface. The range is 3kΩ to 26.5kΩ

Overload protection

When a PoE-Out port is powered-on, it is constantly checked for overload. If overload is detected, PoE-Out is turned off on the port to avoid damage to the PD or PSE.

In seconds the PoE Out feature will be turned on again to see if the environment has changed and PD can be supplied with power again. That is important for configurations that are not connected to mains (solar installations, equipment running on batteries due to mains failure) so that when voltage drops — overload will be detected and connected devices turned off. After a while when voltage level returns to usual operating value — connected equipment can be powered up again.

Short circuit detection

When power is enabled on PoE-Out port, PSE continuously checks for a short circuit. If it is detected to ensure that there is no additional damage on PD and PSE, the power is turned off on all ports. PSE will continue to check PoE-Out port until environment returns to normal.

Warning: Make sure that non-standard incompatible PD which does not have the resistance range 3kΩ to 26.5kΩ are not attached, so the PSE would not try to apply power on them

MikroTik supported PoE-Out standards

MikroTik devices can support some or all of the following PoE standards:

Passive PoE-Out up to 30 V — PoE standard, which does not require negotiation between PSE (Power Sourcing Equipment) and PD (Powered Device). For PoE-out uses the same voltage as supplied to the PSE (Power Sourcing Equipment). PoE-Out Standard for devices which supports input voltage up to 30 V. PD resistance on spare pairs should have range from 3kΩ to 26.5kΩ. (e.g. hEX PoE lite, RB3011UiAS-RM, RB2011iL-IN.)

Passive PoE-Out up to 57 V — Works same as low voltage (up to 30 V) PoE-Out, but is also capable to deliver high voltage over PoE ports. The output voltage depends from the power source connected to PSE. Can power up af/at compatible devices, which accepts power over 4,5 (+) and 7,8 (-), and does not require PoE negotiation. PD resistance on spare pairs should have range from 3kΩ to 26.5kΩ. (e.g. cAP ac, hAP ac, wsAP ac lite.)

IEEE Standards 802.3af/at — Also called PoE Type 1/PoE+ Type 2, are PoE standards Defined by the IEEE. The aim of these standards is to reduce incompatibility between vendors. MikroTik PSE with af/at support is capable of powering both a Type 1 and a Type 2 PD. Valid PD should have PoE-In resistance from 23.75kΩ to 26.25kΩ. MikroTik devices which support af/at standard can also switch to Passive PoE-Out mode. (e.g. hEX PoE, CRS112-8P-4S-IN, CRS328-24P-4S+RM.)

Each PoE-Out implementation supports overload and short-circuit detection.

Note: Some MikroTik devices support all of the described standards (e.g. hEX PoE, PowerBOX Pro, CRS112-8P-4S-IN etc…)

PoE-Out notifications

PoE-Out LEDs

Models with dependant voltage output

PoE-Out LED behaviour can differ between models, but most of them will indicate PoE-Out state on one additional LED. Devices with one voltage output will light:

• Red colour LED — PoE-Out port state is powered-on (auto or forced-on mode).
• Blinking Red colour LED — PoE-Out port state is short-circuit

Models with selectable voltage output

Models with multiple voltage options can indicate additional information:

• Green colour triangle LED — PoE-Out port state is powered-on (auto or forced-on mode), PD uses low voltage.
• Red colour triangle LED — PoE-Out port state is powered-on (auto or forced-on mode), PD uses high voltage (af/at or passive).
• Blinking Green colour triangle LED — PoE-Out port state is short-circuit or overload
• Blinking Red colour triangle LED — PoE-Out port state is short-circuit or overload

Model-specific LED behaviour

PoE-Out Logs

To avoid unnecessary logging in cases when PD is not powered because of current-too-low, RouterOS will filter such events, and add one log per every 512 current-too-low events.

Logs can be disabled if necessary:

/system logging set  topics=info,!poe-out 
/system logging set  topics=warning,!poe-out 

PoE-Out Warnings in GUI/CLI

To notify a user about important PoE-Out related problems, messages will be shown in Winbox / Webig and CLI interface fields:

     1  RS ;;; poe-out status: overload
       ether1                              ether            1500  1588       9204 64:D1:54:61:D5:E0

Webfig and Winbox will notify user under interfaces:
