Reset button

The RouterBOOT reset button has the following functions. Press the button and apply the power, then:

Release the button when green LED starts flashing, to reset RouterOS configuration to defaults.
Release the button when the LED turns solid green to clear all configuration and bridge all interfaces.
Release the button after LED is no longer lit (

Regardless of the above option used, the system will load the backup RouterBOOT loader if the button is pressed before power is applied to the device. Useful for RouterBOOT debugging and recovery.

Connect the Ethernet cable from the device to the POE port of the POE adapter.
Connect an Ethernet cable from your LAN to the LAN port of the POE adapter, please mind arrows for data and power flow.
Connect the power cord to the adapter, and then plug the power cord into a power outlet.

The package includes the following accessories that come with the device:

The device supports RouterOS software version 6. The specific factory-installed version number is indicated in the RouterOS menu /system resource. Other operating systems have not been tested.

PoE-Out Monitoring

RouterOS

MikroTik devices with PoE-Out controller (not injector) provides port monitoring option. /interface ethernet poe monitor [find]

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 power-on to happen there should be resistance on spare pairs 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.
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;

If power-cycle-ping feature is used, /interface ethernet poe monitor [find] 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)

It is possible to monitor PoE-Out values using SNMP protocol, this requires enabled SNMP on PSE. SNMP Wiki

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, snmp-walk 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 snmp-get 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

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.

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

Property	Description
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 (time:0..1m \|; Default: 5s)	Disables PoE-Out power for a specified period of time.

Global Settings

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

Property	Description
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

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 /interface ethernet poe menu. Each port can be controlled independently.

auto-on - the board will attempt to detect if power can be applied on the port. For power-on to happen there should be resistance on spare pairs 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

Highest priority is 0, 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.

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.

Property	Description
power-cycle-ping-enabled (yes \| no; Default: no)	Enables ping watchdog, power-cycles port if a host does not respond to ICMP or MAC-Telnet packets.
power-cycle-ping-address (IPv4 \| IPv6 \| MAC; Default: )	An address which will be monitored. Since RouterOS 6.46beta16, an active route towards PD is required in case an IP address is configured, so make sure PSE can reach the PD. In case MAC address is specified, PSE will send MAC-Telnet ping requests only from specified ethernet interface. When configuring a bridge vlan-filtering or some way of VLAN switching, it is recommended to use IP address for monitoring your PD.
power-cycle-ping-timeout (time:0..1h \|; Default: 5s)	If the host does not respond for more than <timeout> period of time, then PoE-Out port is switched off for 5s.
power-cycle-interval (time\| any; Default: )	Disables PoE-Out power for 5s between specified interval. Not related with power-cycle-ping feature.

If power-cycle is enabled, /interface ethernet poe monitor will show actual status of the host and time when power cycle will be performed [1]

SwOS interface provides basic PoE-Out configuration options:

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

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). PoE-out uses the same voltage as supplied to the PSE (Power Sourcing Equipment). PoE-Out Standard for devices that supports input voltage up to 30 V. PD resistance on spare pairs should have ranged from 3kΩ to 26.5kΩ. (e.g. hEX PoE lite, RB3011UiAS-RM, RB2011iL-IN.)

Passive PoE-Out up to 57 V - Works the 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 on 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 ranged from 3kΩ to 26.5kΩ. (e.g. cAP ac, hAP ac, wsAP ac lite.)

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

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 total limitation

PSE has also a total PoE-Out current limitation which can't be exceeded, even if individual port limit allows it.

PoE Out polarity

All MikroTik PSE uses the same PoE-Out pin polarity Mode B 4,5 (+) and 7,8 (-), however other vendors can use opposite or Mode A pinout on PD, this would require using a special crossover cable.

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

Model-specific features

Legacy

PoE-Out Controller upgrade

PoE-Out devices which are running RouterOS 5.x can also hold old PoE-Out controller firmware, upgrade to RouterOS 6.x will automatically update the PoE-Out firmware. Changes between 1.x and 2.x PoE-Out controller firmware will result in higher Max-port limits (0.5A to 1A) in case if it's supported by the hardware, also will provide some additional data which can be monitored, and allow to use PoE-Out priorities.

All MikroTik devices which come with RouterOS 6.x already support the latest PoE-Out firmware.

hEX PoE is a powerful five-port Gigabit Ethernet router with an SFP port capable of powering other devices.

This device is designed for use indoors by placing it on the flat surface or mounting on the wall, mounting points are shown in the picture below, screws are not included in the package. Screws with size 4x25 mm fit nicely, depending on your wall structure you can use dowels 6x30 mm and 6 mm drill bit if needed.

When mounting on the wall, please ensure that the cable feed is pointing downwards. We recommend using Cat6 cable for our devices. The IP rating scale for this device is IPX0.
Warning! This equipment should be installed and operated with a minimum distance of 20 cm between the device and your body. The operation of this equipment in the residential environment could cause radio interference.

The device accepts power from the power jack or from the first Ethernet port (Passive PoE):

Direct input power jack (5.5mm outside and 2mm inside, female, pin positive) accepts 12 - 57 V ⎓DC.
The first Ethernet port accepts passive Power over Ethernet 12 - 57 V ⎓DC.

The power consumption of this device under maximum load with attachments is 59 W. Without attachments 6 W.

This device can supply PoE power to external devices from its Ethernet ports. This is convenient as you don't need any additional PoE injectors to power other devices. The output voltage will be the same as the input voltage. The maximum power output of each Ethernet port in this mode is 1 A (the total maximum for all ports is 2 A). Once Power Output is enabled in RouterOS, the Ethernet LED adds red color to it (green means Ethernet link is made, red means power but no link, red and green both means there is link and power).

The device has five individual Ethernet ports, supporting automatic cross/straight cable correction (Auto MDI/X), so you can use either straight or cross-over cables for connecting to other network devices.
1G SFP port.
USB type-A slot.

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 0 is the highest priority, 99 - lowest

Setting up priority

Example of how to set priorities from CLI:

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

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 <interface>

Power-cycle ping

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.

Troubleshooting

In cases where a PD does not power-up or reboots unexpectedly when powered from your PSE, it's suggested to the 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 the 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:
- Check if you are using good quality ethernet cables, it's important especially in cases if PoE is used.
- 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 pinouts can be unable to powerup from all PSE. Check the PD datasheet.
- Incompatible resistance - PD resistance on spare pairs should have ranged from 3kΩ to 26.5kΩ (For Passive-PoE) and from 23.75kΩ to 26.25kΩ on af/at.

В данной статье проверим на что способна новинка MikroTik RB750UP, настроим порты и проведем тест на максимальное количество подключенных устройств по питанию POE. Итак, приступим. Открываем коробку и перед нами собственной персоной RB750UP и блок питания 24V 1.6A(100-240V

Данное устройство по техническим параметрам идентично своему предку RB750 Mikrotik, НО есть изюминка. Главными преимуществами являются порты RB 750 up - 4шт. Ethernet по которым можно запитывать другие устройство используя технологию POE и плюс 1шт. USB порт. Данное решение давно ждали на рынке ИТ, так как оно позволит избавится от кучи проводов и централизует несколько устройств сразу. А USB порт позволит использовать USB модемы для подачи интернета в труднодоступных местах. У всех продвинутых ИТшников сразу возникли вопросы "Сколько же на самом деле способен запитать Mikrotik RB 750up?!", "Сможет ли адаптер питания, который всего-то 24V 1.6A, запитать одновременно 4 устройства?!". Нам тоже стало интерестно и мы решили проверить.

НАЧНЕМ ТЕСТ RB750 UP:

Решили начать с беспроводного оборудования, долго не искали взяли Ubiquiti Nanostation2 - требует 12V 1A. Подключаем точку доступа и..ничего..питание не пошло..сразу поняли в чем дело. Заходим на наш Микротик и в разделе Interface -> закладка Generalвключаем подачу питания РОЕ:

Ура, питание пошло. Далее заходим на точку и подключаемся в режиме Station к раздающей точке доступа. Коннект прошол, пакеты пошли. Но на этом мы не остановились, одного устройства мало. Подключаем вторую точку Nanostation2 UBNT к RB750UP.Коннектимся в режиме Station к раздающей точке доступа - пакеты пошли:

Попытка подключить и настроить очередную Nano station 2 оказалась провальной. После подключения точки пинги пропали и зайти на любую из трех точек стало не возможно. Впринципе чего и следовало ожидать, так как не для продукции Ubiquiti была разработана данная модель Mikrotik.

Итог по беспроводному оборудованию - максимально возможно подключить всего лишь 2 точки доступа Ubiquiti в активном подключенном режиме. На остальные свободные порты легко можно подключить какой либо роутер или маршрутизатор Mikrotik. Что можно сказать о подлючении и запитыванию маршрутизаторов, роутеров и свичей - RB750UP Mikrotik легко справится с этой задачей (на примере теста из нескольких RB411AH Mikrotik с Minipci картами R52n).

Наш вердикт - новинка RB750up очень нужный и полезный маршрутизатор который на данный момент почти не имеет аналогов. Маршрутизатор RB750up станет полезным как для больших провайдеров так и для малых сетей.

Делитесь практикой использования и RB750up отзывы помогут начинающим юзерам .

MikroTik supported PoE-Out standards

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

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 examples

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

The priority of 0 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 the overload is detected, ether5 will be turned off (lowest priority), then recheck is done and if the 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 <interface>

[admin@MikroTik] > interface ethernet poe monitor [find]
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

/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.

PoE-Out Monitoring

RouterOS

MikroTik devices with PoE-Out controller (not injector) provides port monitoring option. /interface ethernet poe monitor [find]
- 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 power-on to happen there should be resistance on spare pairs 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 voltage provided from PSE.
- current-too-low - current-too-low means that PD draws too low current (<10mA) than normal PoE-Out device should, reason for this can be:
Delivered voltage at PD is too low for normal powering (for example Vmin = >30V, but provided 24V);

PD uses second power source which has a higher voltage than PSE, so all current is taken from second DC source, not PSE PoE-Out port;
- off - all detection and power is turned off for this port;
If power-cycle-ping feature is used, /interface ethernet poe monitor [find] will show additional fields:

It is possible to monitor PoE-Out values using SNMP protocol, this requires enabled SNMP on PSE. SNMP Wiki

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, snmp-walk will print current mA from all available PoE-Out ports:

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

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.

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

By default PoE-Out event logging is enabled and uses "warning" and "info" topics to notify the user about PoE-Out state changes. Log entries will be added on each PoE-Out state change. Important logs will be added with "warning" topic, informative logs will be added with "info" topic.

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:

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:

Webfig and Winbox will notify user under interfaces:

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:
  - Check if you are using good quality ethernet cables, it's important especially in cases if PoE is used.
  - 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 devices which are running RouterOS 5.x can also hold old PoE-Out controller firmware, upgrade to RouterOS 6.x will automatically update the PoE-Out firmware. Changes between 1.x and 2.x PoE-Out controller firmware will result in higher Max-port limits (0.5A to 1A) in case if it's supported by the hardware, also will provide some additional data which can be monitored, and allow to use PoE-Out priorities.
  
  All MikroTik devices which come with RouterOS 6.x already support the latest PoE-Out firmware.
