Claim the device to your organization inventory. You will need your Meraki order number (found on your invoice) or the serial number of each MG, which looks like Qxxx-xxxx-xxxx, and is found on the bottom of the unit. You will also need to claim your Enterprise license key, which you should have received via email.
Find or create the network to which you plan to add your MG52/52E.
Add your MG52/52E to the network.

Check and Set Firmware

To ensure your MG52/52E performs optimally immediately following installation, it is recommended that you facilitate a firmware upgrade prior to using your MG52/52E.

Insert an active nano (4FF) SIM card/cards into the SIM trays before powering up the device.
Connect your MG52/52E to power.
The MG52/52E will turn on and the power LED will glow solid orange until it comes online.
If the unit requires a firmware upgrade after coming online, the power LED will begin blinking white until the upgrade is complete, at which point the LED will turn solid white or purple. You should allow at least a few minutes for the firmware upgrade to complete, depending on the speed of your internet connection.

Check and Configure Upstream Firewall Settings

If you are testing Wired WAN Mode on port 1 and have an upstream firewall in place, the firewall must allow outgoing connections on particular ports to specific IP addresses. The most current list of outbound ports and IP addresses for your organization can be found on the Help > Firewall Information page in your dashboard.

Collect Tools

You will need the following tools to perform an installation:

T8 Torx screwdriver, Phillips screwdriver, Hammer, Drill with 1/4" (6.3mm) bits

Collect Additional Hardware for Installation

You will need the following hardware to perform an installation:

802.3af PoE source (either PoE switch or Meraki 802.3af PoE injector), AC adapter, Network cables RJ45 connectors long enough for your particular mounting location

Installation Instructions

Mounting Hardware

The supplied wall screws and anchors allow you to mount the appliance on a drywall surface, either vertically or horizontally. For mounting on drywall, use a ¼- inch drill bit, then insert the plastic and screw assemblies.

For mounting on wood or a similar surface, use only the screws.
Allow the heads of the screws to stick out far enough to be inserted securely into the back of the MG.

Plan Ahead: When mounting the MG cellular gateway in hard to reach areas, it is recommended that Ethernet cables are run to both ports as a redundant method to access both ports in the case of physical failure of a port or cable.

Connecting to WAN

All Meraki MG devices must have an IP address. This section describes how to configure the WAN interface 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.

Note: All the settings below are accessible only via the local status page.

Setting up Cellular Connection

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

Follow the steps below to configure basic connectivity and other cellular gateway parameters on the MG52/52E:

Using a client machine such as a laptop, connect directly to LAN interface of the MG.
Find the client's IP address and default gateway. Using a browser on the client machine, access the appliance's built-in web service by browsing to mg.meraki.com or the default gateway IP (You do not have to be connected to the Internet to reach this address).
Click the Configuration tab under the Local Status tab. The default credentials are the Serial Number of the device (all upper-case with dashes) as the username and a blank password field.
Configure additional bearer values like APN if required by your carrier under the Configuration tab.

Configuring Ethernet Ports

To configure physical link settings on the Ethernet ports, click on Ethernet tab. You can enable half duplex, full duplex, and auto-negotiation, as well as set 10 or 100 or 1000-Mbps data rates on Ethernet ports.

Basic Troubleshooting

The following steps can be used for troubleshooting basic connectivity issues with your MG:

MG devices require a valid and active data plan, so make sure the SIM and data plan are active. SIM size for MG52/52E is nano (4FF).
Some carriers require specific APNs, usernames/passwords. Ensure the values are correct if required.
Validate signal quality is sufficient by checking the RSRP and RSRQ values on the Connection tab of the Local Status Page.
Swap the SIM card to the secondary SIM slot from the primary slot (A new unit will treat SIM slot 1 as primary unless changed via dashboard/LSP)
Try connecting the MG in Wired WAN Mode and check if it comes online on Dashboard.
Try a soft reset by pressing the reset button for 1 second to delete a downloaded configuration and reboot the MG. • Try a factory reset by holding the factory reset button for at least 10 seconds.
Try switching cables, or testing your cables on another device.

Note: If the MG52/E fails to get online or the LED remains RED after all the above steps. Please check the Local Status Page and move your device to an area where the signal conditions are better.

Device power issue

If the device fails to turn on, check the power source to make sure it is adequately supplying power to the MG.
If there are no LED lights even though there is power at the outlet, check the MG to make sure everything is plugged in properly.
If the device isn't coming after trying both AC adapter and POE, check that the power options also work on other devices in a similar or matching setup.

If you are still experiencing hardware issues, please contact Cisco Meraki Support by logging in to dashboard and using the Help > Get Help option at the top of the page, then opening an email case or calling the Meraki Support center using the contact information on that page.

How do I know if my MG52/E is on 5G SA or NSA?

MG52 uses a 5G technology known as 5G SA (Standalone). The alternative to this is known as 5G NSA (Non-Standalone). The core difference between these technologies (NSA / SA) is in the control signaling of the Radio Access Network (RAN).

On 5G SA, the control signaling is handled directly on the 5G network. This allows the 5G SA connection to be established purely over 5G without the requirement of a 4G LTE connection.

Via Dashboard:

Within the Uplink tab of the MG status page on the dashboard, the radio status section is displayed. For MG52 this displays both the current 4G and/or 5G radio status including current bands and signal strength.

When the MG has established a 5G SA connection, then the 5G SA radio bands (with or without 5G band Carrier Aggregation (CA)) will be displayed on the cellular uplinks tab on the dashboard . The important thing to note here is that there will be no 4G bands displayed when the MG is connected on the 5G SA network.

For NSA 5G, the control signaling is anchored to the 4G LTE network and requires a 4G LTE connection to establish before being able to establish the 5G service. Essentially, a 5G NSA connection is required to be built on top of an existing 4G LTE connection.

When the MG has established a 5G NSA connection the radio status of both the 4G LTE and 5G NSA radio will be displayed since the 4G is the base connection.

Note: When a 5G connection is not in use, the 5G status will show "Inactive":
