Safety Warnings

Before you work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard practices for preventing accidents.
Ultimate disposal of this product should be handled according to all national laws and regulations.
The Installation of the equipment must comply with local and national electrical codes.
This unit is intended to be mounted on a pole. Please read the wall mounting instructions carefully before beginning installation. Failure to use the correct hardware or to follow the correct procedures could result in a hazardous situation for people and damage to the system.
Read the installation instructions before connecting the system to the power source.

It is the customer's responsibility to follow local country regulations, including operation within legal frequency channels, output power, cabling requirements, and Dynamic Frequency Selection (DFS) requirements. All Mikrotik radio devices must be professionally installed.

The LHG is an outdoor wireless router with a built-in directional antenna. It can be used as a CPE or for point-to-point links (use RouterOS wireless mode "bridge" to work as a single-client AP for point-to-point scenarios).

Connecting

• Open the Ethernet door to connect an Ethernet cable to the Ethernet port, connect the other end of the Ethernet cable to the included PoE injector.
• Plug the PoE injector into your network switch or computer.
• Plug the included power supply into the PoE injector to start up the device.
• Download WinBox configuration tool https://mt.lv/winbox;
• Default IP: 192.168.88.1, user name: admin and there is no password, or use Neighbors tab and connect through MAC address;
• Once connected configure the device, so it has an active Internet connection https://mt.lv/configuration;
• Upgrade the RouterOS software to the latest version https://mt.lv/upgrade;
• Connect again and in the QuickSet menu choose your country, to apply country regulation settings;
• Set up your router password in the bottom field to the right and repeat it, it will be used to log in next time.

The device is preconfigured as a wireless client and all you need to do is select the AP to connect to and set a device password. You can do this in the QuickSet tab that is opened by default.
In case the IP connection is not available, Winbox can be used to connect to the MAC address of the device. In case you wish to boot the device from the network, for example, to use MikroTik Netinstall, hold the RESET button of the device when starting it, until the LED light turns off, then the device will start to look for Netinstall servers.

Assembly and Mounting

1. Attach the two legs to the LHG case.
   
2. Snap the assembled LHG unit to the grid in the appropriate locations.
3. Fix the legs in place with two self-thread screws (Use Phillips screwdriver PH2).
   

The device is designed to be mounted on the pole using zip ties or steel clamps as shown in the picture. The clamping diameter with provided steel clamps is 35 – 70 mm.

1. Guide provided steel clamps through the unit.
2. Attach the device to the pole.
3. Align and tighten the clamps to secure the device.
   Optional: If required, before mounting the unit, you can insert the included 5-degree adjustment adapter into the top or bottom slot where the mounting ring is inserted. This will create an additional upward or downward angle when the unit is tightened to a vertical pole.

The device includes a grounding connection (marked ⏚) which you should connect to the grounding installation of the tower or building where the device will be used. This is to substantially reduce the risk of ESD and lightning damage.
Warning! This equipment should be installed and operated with a minimum distance of 40 cm between the device and your body. The operation of this equipment in the residential environment could cause radio interference.

Connect the Ethernet cable to the Ethernet port located under the door and guide through the leg as shown in the picture:

Additional mounting brackets can be purchased separately:

Powering

The device accepts powering only from Passive PoE injectors.
Connecting to a POE Adapter:

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

Configuration

Once logged in, we recommend clicking the "Check for updates" button in the QuickSet menu, as updating your RouterOS software to the latest version ensures the best performance and stability. For wireless models, please make sure you have selected the country where the device will be used, to conform with local regulations.
RouterOS includes many configuration options in addition to what is described in this document. We suggest starting here to get yourself accustomed to the possibilities: https://mt.lv/help. In case an IP connection is not available, the Winbox tool (https://mt.lv/winbox) can be used to connect to the MAC address of the device from the LAN side (all access is blocked from the Internet port by default).
For recovery purposes, it is possible to boot the device from the network, see a section Reset button.

Extension slots and ports

• One Ethernet port, 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.
• One Integrated 2x2 MIMO wireless device with a built-in grid antenna.

LHG 2 Dual chain 18 dBi, 2.4GHz, 802.11b/g/n. Maximum power consumption 5 W.
LHG 5 Dual chain 24.5 dBi, 5GHz, 802.11 a/n. Maximum power consumption 6 W.
LHG HP5 Dual chain 24dBi, 5GHz, 802.11 a/n. Maximum power consumption 7 W.
LHG 5 ac Dual chain 24.5dBi, 5GHz, 802.11 a/n/ac. Maximum power consumption 8 W.

Reset button

The reset button has three functions:

• Hold this button during boot time until the LED light starts flashing, release the button to reset the RouterOS configuration (total 5 seconds).
• Keep holding for 5 more seconds, LED turns solid, release now to turn on CAPs mode (total 10 seconds).
• Or keep holding the button for 5 more seconds until LED turns off, then release it to make the RouterBOARD look for Netinstall servers (total 15 seconds).

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.
