# MikroTik hEX PoE by SNMP
## Overview
The template for monitoring Ethernet router MikroTik hEX PoE.
5x Gigabit Ethernet with PoE output for four ports, SFP, USB, 800MHz CPU, 128MB RAM, RouterOS L4
## Requirements
Zabbix version: 7.0 and higher.
## Tested versions
This template has been tested on:
- MikroTik hEX PoE
## Configuration
> Zabbix should be configured according to the instructions in the [Templates out of the box](https://www.zabbix.com/documentation/7.0/manual/config/templates_out_of_the_box) section.
## Setup
Refer to the vendor documentation.
