Frequently Asked Questions - ER-4 Ubiquiti Networks

What is the Ubiquiti ER-4 EdgeRouter 4?

The ER-4 is a high-performance Gigabit Ethernet router designed for small and medium businesses. It offers 4 Gigabit ports and 1 SFP port, with advanced routing and firewall capabilities powered by EdgeOS.

How do I reset the ER-4 to factory defaults?

Press and hold the Reset button on the front panel for about 10 seconds until the LED blinks rapidly. The device will reboot with default settings.

What power supply does the ER-4 need?

It requires a 12V DC, 2A adapter with a 2.1mm center-positive barrel connector. Use only the included or compatible power supply.

Can the ER-4 be rack-mounted?

Yes, with an optional rack-mount bracket (sold separately). It also fits in a standard 19-inch rack when used with the bracket.

Does the ER-4 support VPN connections?

Yes, it supports IPsec, OpenVPN, L2TP, and PPTP VPN protocols for secure site-to-site and remote access connections.

How do I update the firmware on the ER-4?

Download the latest firmware from the Ubiquiti website. Log into the web UI (usually 192.168.1.1), go to System > Firmware, upload the .tar file, and apply.

What is the maximum throughput of the ER-4?

With hardware acceleration, the ER-4 can achieve up to 2 Gbps for large packets and about 1 million packets per second.

Is the ER-4 fanless?

Yes, the ER-4 uses passive cooling with no internal fans, making it silent and reliable for office environments.

Can I use the ER-4 as a switch?

While primarily a router, it can function as a layer 3 switch with inter-VLAN routing. Port switching is configurable via EdgeOS.

What should I do if the ER-4 is not booting?

Check the power adapter and cable. Try a different outlet. If the LED is off, the power supply may be faulty. Use a serial console (RS232 via mini-USB) to diagnose boot issues.

TERMS OF USE: All Ethernet cabling runs must use CAT5 (or above). It is the professional installer's responsibility to follow local country regulations, including operation within legal frequency channels, output power, indoor cabling requirements, and Dynamic Frequency Selection (DFS) requirements.

Installation Requirements

• 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 Networks. For more details, visit:

www.ubnt.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.

Hardware Overview

Front Panel Ports

Interface Description
Console	RJ45 serial console port for Command Line Interface (CLI) management. Use an RJ45-to-DB9, serial console cable, also known as a rollover cable, to connect the Console port to your computer. (If your computer does not have a DB9 port, then you will also need a DB9 adapter.) Then configure the following settings as needed:·Baud rate 115200·Data bits 8·Parity NONE·Stop bits 1·Flow control NONE
USB Reserved for future use.
RJ45 (eth0-eth2)	RJ45 ports support 10/100/1000 Ethernet connections.
SFP (eth3)	SFP port is hot-swappable and supports Gigabit fiber SFP modules.

Front Panel Button

Button Description

Reset

There are two methods to reset the EdgeRouter to factory defaults: ·Runtime reset (recommended) The EdgeRouter should be running after bootup is complete. Press and hold the Reset button for about 10 seconds until the LED for port eth3 starts flashing and then becomes solidly lit. After a few seconds, the LED will turn off, and the EdgeRouter will automatically reboot. ·Power-on reset Disconnect the Power Cord from the Power Adapter. Press and hold the Reset button while connecting the power (refer to Connecting Power for details). Keep holding the button until the LED for port eth3 starts flashing and then stops flashing after a few seconds.

Note: There are additional ventilation holes on the sides of the EdgeRouter.

Hardware Installation

WARNING: FAILURE TO PROVIDE PROPER VENTILATION MAY CAUSE FIRE HAZARD. KEEP AT LEAST 20 MM OF CLEARANCE NEXT TO THE VENTILATION HOLES FOR ADEQUATE AIRFLOW.

Wall Mounting

To mount the EdgeRouter on a wall, you will need a drill, a 6 mm drill bit, and a Phillips screwdriver.

1. Use a 6 mm drill bit to drill two holes 125 mm apart.
2. Insert the Wall Mount Anchors into the holes. Use a Phillips screwdriver to secure a Wall Mount Screw to each anchor. Leave a clearance of approximately 3 mm between each screw head and its anchor.

Note: You can also mount the EdgeRouter in a vertical orientation.

1. Position the EdgeRouter with the Ethernet ports facing down. Place the wall-mount slots of the EdgeRouter over the screw heads on the wall. Then slide the EdgeRouter down to lock it into place.

Grounding the EdgeRouter (Recommended)

The EdgeRouter is grounded through the Power Cord; however, you can add optional ESD grounding for enhanced ESD protection.

1. Attach a screw (not included) to secure a ground wire (not included) to the Grounding Point.
