Z3C Overview

The Meraki Z3C is 802.11a/b/g/n/ac Wireless Security Appliance designed for telecommuting employees and IT staff. It is also a great all-in-one device to test the capabilities of Meraki's cloud-managed networking. This gateway provides the following features:

  • 4 wired ports with one PoE-powered port, ideal for phones
  • 1 GbE WAN port, 4 GbE LAN ports
  • 3G / 4G failover via CAT 3 LTE or USB modem
  • Dual-band 802.11ac Wave 2 radios
  • 2x2 MU-MIMO, up to 1.3 Gbps data rate
  • Wall screws and anchors for mounting to a drywall surface, either vertically or horizontally

Package contents

In addition to the Z3C, the following are provided.

LAN ports

These 4 ports provide connectivity to computers, printers, access points, or Ethernet switches.

A steady green LED indicates bidirectional connectivity, and flashing green indicates traffic.

PoE+ Port

One of the LAN port provides PoE+ for connectivity to computers, printers, access points, or Ethernet switches, up to 15W of PoE power.

The Z3C Bottom Panel




Please note that the serial number is located on the product label on the bottom panel of the Z3

Mounting Hardware

The supplied wall screws and anchors allow you to mount the gateway on a drywall surface, either vertically or horizontally.

  • For mounting on drywall, use a ¼-in 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 gateway.

Connecting to WAN

All Meraki Z3C 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 gateway, 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

Note: 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 one of the four LAN ports of the Z3C.
  2. Using a browser on the client machine, access the gateway'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 Z3C devices are configured to DHCP from upstream WAN / ISP servers. Simply plug the Z3C's WAN / Internet port to your upstream circuit and wait a few minutes for the unit to negotiate a DHCP address. If your Z3C device was configured to have a static address (and not attempt to negotiate DHCP), you can held the reset button while the device is powered until the lights on the device turn off. Doing so will return the Z3C device to its default DHCP settings.

Note: When the WAN connection is fully enabled, the device's front LED will be solid white.

Setting up Cellular Failover

The Z3C has an embedded LTE module for cellular failover connections. The following section will walk through first-time set-up of a Z3C with an internet connection as a primary connection and cellular as failover.


Note that the IMEI cannot yet be found on the Meraki dashboard, only on the physical label of the device. The IMEI of the MXs with embedded LTE, as well as the serial number and MAC address, can be found on the product label at the bottom of cellular-embedded MX devices.

To set up the cellular failover connection, follow the steps below:


  1. Power off the Z3C. Swapping/installing SIM cards while the Z3C is powered on may cause unexpected behavior or errors

  2. Open the SIM tray using the SIM card removal tool included in the box

  3. Insert a nano SIM card (4FF size) and close the SIM tray

  4. Connect the uplink for the Z3C device via a wired connection to connect to the Meraki cloud

  5. Power on the Z3C and wait for the Z3C to show as online in the Meraki dashboard

  6. Check with the carrier of choice if an APN needs to be configured. If so, do that from the Meraki Dashboard under Teleworker Gateway > Monitor > Appliance Status > Uplink tab

  7. Navigate to Teleworker Gateway > Monitor > Appliance Status > Uplink tab and next to Status, select the edit (pencil) button and then select Enabled. When the cellular uplink is successfully connected, you will be able to see the status on the left hand side of the Appliance Status page and in the Uplink tab. The connection will say Ready when it is successfully connected

  8. Test the cellular failover connection by unplugging the wired connection or by using the traceroute tool under Teleworker Gateway > Monitor > Appliance Status in the Tools tab

  9. If, after following the steps above, the SIM card is not detected, please confirm with your carrier that the SIM card is active and has data. You will need the ICCID of the SIM card and IMEI of the device to get troubleshooting help from the carrier

  10. Please contact the Meraki Support team if the cellular connection is still not being recognized after following the steps above

Additional Settings

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 Z3C 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 Z3C 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 gateway, 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.

Power Efficiency Modes

The Meraki Z3C Teleworker Appliance has an off mode and a networked standby or efficient idle mode, both with power consumption less than 12W.

In off mode, the power consumption is a measured 0.3W. In the networked standby or efficient idle mode, the power consumption is under that of full operation mode, which is a measured 6.6W. This mode is initiated after treating the last payload packets.

To activate and/or deactivate wireless network ports, you may use the physical on/off switch or deactivate through the Meraki Dashboard.
