# 1.2 Interfaces Overview

Introduction to the enclosure and outside physical interfaces of the outdoor router.

## Interfaces

Introduction to the outside physical interfaces of the outdoor 4G router.

EZR34T-LTE router has 4x antenna sockets, 1x gland socket, 1x breather valve, and 1x lock hole.

All of the antenna sockets are N-female type. 4G antenna sockets are on the top side, and Wi-Fi antenna sockets are on the bottom.

***\[1\~6]** are the embossed numbers on the enclosure. \[2] The top side is for spare uses.*

There are two types of ends on the T-shape wrench. The hexagon end fits the hexagon bolts on the lid. The cross end is fit to cross-headed screws on the backside. Use one of the Hexagon ends on the wrench and turn in an anti-clockwise direction to lose the bolts on the lid. Then, we can open the enclosure.

## Seal the Enclosure

Close the lid & press it with your hand. Then, use the hexagon end on the T-wrench to tighten four pieces of bolts on the lid. After closing the enclosure, please review and ensure no gap after tightening the screws!
