Please note that the serial number is located on the product label at the back panel of the MX450-HW.


Mounting Hardware

The mounting hardware includes four sets of standard slot-head rack screws and nuts. The additional screws and nuts are different screw standards meant to accommodate the most common rack mounts. When installing the appliance, make sure that there is sufficient space between the rear of the rack and other obstacles to ensure adequate airflow. Ventilation is from side to side not from front to back. This MX security appliance requires a minimum of 10mm clearance between the venting holes and any obstruction.


Safety Guidelines


Warning: The system must be disconnected from all sources of power and the power cord removed from the power supply module(s) before accessing, installing, or removing system components.




Caution: The Optical Transceiver product should use UL listed, and Rated Laser Class I, 3.3Vdc.


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 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 Pettings 

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.
