This document describes how to install and set up the MX100 security appliance. Additional reference documents are available online at:

MX100 Overview

The Meraki MX100 is an enterprise security appliance designed for distributed deployments that require remote administration. It is ideal for network administrators who demand both ease of deployment and a state-of-the-art feature set. This security appliance provides the following new features:

  • Two GbE SFP connections (requires optional Meraki SFP-1GB-SX transceiver).
  • USB port, to support approved 3G/4G cards for failover to cellular networks.
  • 1TByte cache storage for WAN acceleration.
  • LAN 2 port can be configured to be a LAN or WAN connection, allowing support up to 2 WAN connections.
  • Dedicated management port.
  • Front-panel rack mounts.

Mounting hardware

The mounting hardware includes four sets of standard slot-head rack screws and nuts. The additional screws and nuts are for use with optional rear brackets if rear support is required. When installing the appliance, make sure that there is sufficient space between the rear of the rack and other obstacles to ensure adequate airflow. Additionally, other devices should not be placed directly on the MX.

Safety guidelines

Regardless if you are using a wall power outlet (MAINS) or any other type of power connection (e.g., a UPC device), always ensure that the power cord can be readily disconnected from the hardware unit.

MX100 comes with a built-in battery for system date and time. You should never attempt to replace the battery yourself. Return the MX100 to Cisco Meraki for battery replacement. Opening the unit to replace the battery will void the warrant.



Connecting to WAN

All Meraki MX devices must have an IP address. This section describes how to configure your local area network before you deploy it. A local management web service, running on the appliance, is accessed through a browser running on a client PC. This web service is used for configuring and monitoring basic ISP/WAN connectivity.

Setting up a static IP address

To ensure that the client PC is redirected to the local web service in the following step, you must disable all other network services (ex: wi-fi) on your client machine.


Do the following to configure basic connectivity and other networking parameters:

  1. Using a client machine such as a laptop, connect to the management port of the MX.
  2. Using a browser on the client machine, access the appliance's built-in web service by browsing to (You do not have to be connected to the Internet to reach this address)
  3. Click Uplink configuration under the Local status tab. The default credentials use the device serial number as the username, with a blank password field.
  4. Choose Static for the IP Assignment option.
  5. Enter the IP address, subnet mask, default gateway IP and DNS server information.

Setting up a DHCP IP address

By default, all MX devices are configured to DHCP from upstream WAN / ISP servers. Simply plug the MX's WAN / Internet port to your upstream circuit and wait a few minutes for the unit to negotiate a DHCP address.

When the WAN connection is fully enabled, Internet LED will turn green.

Additional settings

Please note that all these settings below are accessible only via the local management console.

Setting VLANs

If your WAN uplink is on a trunk port, choose VLAN tagging > Use VLAN tagging and enter the appropriate value for VLAN ID for your network.

Setting up secondary WAN interface (dual WAN)

You can toggle the LAN2 port between LAN and Internet/WAN through the Local Status Page or in dashboard under Security & SD-WAN > Monitor > Appliance Status > Uplink tab "Add another WAN port..."

Setting PPPoE

PPPoE authentication may be required if you are connecting MX device to a DSL circuit. You need to know your authentication option and credentials (supplied by your ISP) in order to complete these steps.

  • Choose Connection Type > PPPoE.
  • Select your Authentication option.
  • If you select Use authentication, enter appropriate values for Username and Password.

Web proxy settings

These settings take effect if the MX device has to fall back to using HTTP to contact the Cloud Controller. By default, web proxy is disabled. To enable web proxy, do the following:

  • Choose Web proxy > Yes.
  • Enter values as appropriate for Hostname or IP and Port.
  • If you require authentication, choose Authentication > Use authentication, and enter appropriate values for Username and Password.

To apply all configuration settings to the appliance, be sure to click Save Settings at the bottom of the page.

Configuring physical link settings

To configure physical link settings on the Ethernet ports, click Local status > Ethernet configuration. You can enable half duplex, full duplex, and autonegotiation, as well as set 10- or 100-Mbps data rates.

If your Cisco Meraki device fails and the problem cannot be resolved by troubleshooting, contact support to address the issue. Once support determines that the device is in a failed state, they can process an RMA and send out a replacement device free of charge. In most circumstances, the RMA will include a pre-paid shipping label so the faulty equipment can be returned.

In order to initiate a hardware replacement for non-functioning hardware that is under warranty, you must have access to the original packaging the hardware was shipped in. The original hardware packaging includes device serial number and order information, and may be required for return shipping.
