The basic initial configuration of the Z3 and Z3C is just as simple as with other MX/Z devices. The links below provide additional information and instructions relating to each step in getting the device setup and configured for the first time. 

  1. Claim the device to an Organization on the Meraki Dashboard
    1. If a Dashboard Organization does not yet exist, Create one
  2. Add the device to a Dashboard Network 
    1. If a Network does not yet exist, Create one first
  3. Physically connect the device to the local network
    1. Insert an activated SIM card to allow the cellular uplink to function (Cellular model only) 
    2. Power on the device and let it check in to the Dashboard
    3. If necessary, configure a Static IP on the WAN interface through the Local Status Page to allow it to check in.
  4. Finish configuring the device from the Meraki Dashboard 
    1. Manage local VLANs
    2. Modify Firewall rules
    3. Configure VPN connectivity

Certifications PTCRB (US) RCM (ANZ, APAC), GCF (EU)
Tested Carriers AT&T, Bell Canada Orange, Telia, Telecom Italia, Telefonica, Post, BT, STC, Telenor, SingTel

Carrier compatibility is generally based on having compatible bands on the modem. In the open market, carriers may only require regulatory domain certifications and open market certifications, like the PTCRB and GCF, to be compatible for their network. Sometimes carriers will require additional testing before a device can be used on their network. The section Tested Carriers is based on Meraki device certifications being approved by those specific carriers. A carrier being listed above means that they have officially certified the Meraki product for their cellular network. There maybe many unlisted carriers could be functionally compatible with Meraki devices. The list of tested certified carriers is based on the carrier validating Meraki per their network parameter requirements. If a carrier you are looking to use is not listed above, it could be that they do not require additional compliance testing for their network.  

Please note that until certification has been obtained, the Z3C will not work on Verizon's network.

Common Troubleshooting Steps 

My cellular uplink is stuck at 'Connecting'

Built-in Cellular - Ensure that the SIM card is inserted correctly and is activated with the correct PIN entered, if necessary. Ensure there is no USB modem connected as the MX will prefer a USB cellular modem to the internal modem, if available.

USB Cellular - Ensure that the USB Modem is activated and able to pass traffic when connected to a PC. Ensure it is fully connected and powered on when connected to the MX. If a custom APN is needed contact Meraki Support to get it applied. 


My modem is connected but is getting very poor throughput

Meraki strongly recommends that the cellular uplink be used on a 4G connection with good signal strength to provide adequate bandwidth to support using the cellular connection as a backup uplink. If no 4G signal is available or the available signal is low strength the achievable throughput may not be adequate to fully support a remote site and more restrictive traffic shaping rules should be used to ensure traffic is prioritized appropriately. 

Common Event Log Messages 

There are currently no Z3/C specific Event Log entries, for more general information about navigating the Event Log and the types of Events that could be expected please check out our Event Log documentation



Is the Z3C using the Cellular Uplink? 

When the Z3C is using the Cellular Uplink it will display a Pink Status LED instead of the usual White LED.


Is this SD-WAN over LTE?


Can LTE be used as the primary uplink?

No, LTE is currently only supported as a fail-over link and should only be primary during a temporary WAN failure event.


How does LTE work for free trials?

Meraki does not supply SIM cards so while the unit can be trialed, it is up to the end user to procure a working SIM card on a compatible carrier.


Do these models support eSIM capability?

No. Currently, Meraki customers will need to acquire a SIM card from their carrier and install.


Will the LTE devices be available in the USA and Worldwide?

Yes. There will be two models: the North American model and the worldwide model


Should I contact Meraki support for carrier issues?

No, you will need to bring support issues to the carrier for carrier issues.


How do I troubleshoot carrier issues?

The Meraki Dashboard provides the ability to monitor signal strength, performance, and historical traffic for troubleshooting purposes. For additional troubleshooting related to the carrier, the carrier will need to be contacted.


If an external USB cellular modem and the internal LTE SIM card are both connected, which one takes precedence?

The external USB cellular modem will take priority over the internal LTE SIM.


Can I change the APN?

Yes. Custom APNs can be configured from Cellular section of the Uplink tab on the Security Appliance > Appliance Settings page.
