PACKAGE CONTENTS

$ubiquiti-er-4-edgerouter-FIG- $1$$

Installation Requirements

Drill with a 6 mm drill bit (for wall mounting)
Phillips screwdriver
For indoor applications, use Category 5 (or above) UTP cabling approved for indoor use.
For outdoor applications, shielded Category 5 (or above) cabling should be used for all wired Ethernet connections and should be grounded through the AC ground of the power supply.
We recommend that you protect your networks from harmful outdoor environments and destructive ESD events with industrial-grade, shielded Ethernet cable from Ubiquiti. For more details, visit: ui.com/toughcable

WARNING: To reduce the risk of fire or electric shock, do not expose the EdgeRouter to rain or moisture.
Note: Although the cabling can be located outdoors, the EdgeRouter itself should be housed inside a protective enclosure.

Note: The System LED functionality has been updated with firmware v1.10.7. We recommend that you update the EdgeRouter to the latest firmware.

Grounding the EdgeRouter (Recommended)
The Power Cord grounds the device; however, you can add optional ESD grounding for enhanced ESD protection.

Attach a screw (not included) to secure a ground wire (not included) to the Grounding Point. $ubiquiti-er-4-edgerouter-FIG- $7$$
Secure the other end of the ground wire to a grounding block.

Connecting Power
Connect the Power Cord to the Power port and a power outlet.

Accessing the EdgeOS Configuration Interface

The EdgeOS® configuration interface can be accessed via DHCP or static IP address assignment. By default, eth1 is set up as a DHCP client, while eth0 is assigned a static IP address of 192.168.1.1. To configure the EdgeRouter, proceed to the appropriate section: DHCP or “Static IP Address”.

DHCP

Connect an Ethernet cable from eth1 on the EdgeRouter to a LAN segment that has an existing DHCP server. $ubiquiti-er-4-edgerouter-FIG- $11$$
To check the IP address of the EdgeRouter, use one of the following methods:
- Set up the DHCP server to provide a specific IP address to the EdgeRouter based on its MAC address (on the label). $ubiquiti-er-4-edgerouter-FIG- $12$$
- Let the EdgeRouter obtain an IP address and then check the DHCP server to see which IP address was assigned. $ubiquiti-er-4-edgerouter-FIG- $13$$
