This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that the protective device is
rated not greater than: 15 A, 125 Vac, or 10A, 240 Vac. · Please only power the device with the provided power cables to ensure regulatory compliance.

Pre-install Preparation

You should complete the following steps before going on-site to perform an installation.

Configure your Dashboard Network

The following is a brief overview only of the steps required to add an Z4/Z4C to your network. For detailed instructions about creating, configuring and managing Meraki networks, refer to our Managing Dashboard Networks document. Additional resources can also be found via: documentation.meraki.com.

Login to http://dashboard.meraki.com. If this is your first time, create a new account.
Find the network to which you plan to add your Z4/Z4C or create a new network.
Add your Z4/Z4C to your network. You will need your Meraki order number (found on your invoice) or the serial number of each Z4/Z4C, which looks like Qxxx-xxxx-xxxx, and is found on the bottom of the unit. You will also need your Enterprise license key, which you should have received via email.
Go to the map / floor plan view and place each Z4/Z4C on the map by clicking and dragging it to the location where you plan to mount it.

Check and Set Firmware

To ensure your Z4/Z4C performs optimally immediately following installation, it is recommended that you facilitate a firmware upgrade prior to mounting your Z4/ Z4C.

Attach your Z4/Z4C to power and a wired Internet connection.
The Z4/Z4C will turn on and the power LED will glow solid orange.
If the unit requires an upgrade, the power LED will begin blinking white until the upgrade is complete, at which point the LED will turn solid white. 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 an upstream firewall is already in place, it must allow outgoing connections on particular ports to particular IP addresses. The most current list of outbound ports and IP addresses for your particular organization can be found on the firewall configuration page in your dashboard.

Installation Instructions

Mounting Hardware

The supplied wall screws and anchors allow you to mount the appliance on a drywall surface, either vertically or horizontally. The distance between the holes you drill should be 51/8 inches (13 cm).
· 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 appliance.

Connecting to WAN

All Meraki Z4/Z4C 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:

Using a client machine such as a laptop, connect to one of the LAN ports of the Z4/Z4C.
Using a browser on the client machine, access the appliance’s built-in web service by browsing to http://setup.meraki.com. (You do not have to be connected to the Internet to reach this address)
Click Uplink configuration under the Local status tab. The default credentials use the device serial number as the username, with a blank password field.
Choose Static for the IP Assignment option.
Enter the IP address, subnet mask, default gateway IP and DNS server information.

Setting up a DHCP IP Address

By default all Z4/Z4C devices are configured to DHCP from upstream WAN / ISP servers. Simply plug the Z4/Z4C’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 1 will turn green.

Setting up Cellular Failover

The Z4C has an embedded LTE module for cellular failover connections. The following section will walk through first-time set-up of an Z4C 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 Z4Cs 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 Z4C devices.
This custom query should expose the IMEI. Note, it doesn’t always work. To set up the cellular failover connection, follow the steps below:

Power off the Z4C. Swapping/installing SIM cards while the Z4C is powered on may cause unexpected behavior or error.
Open the SIM tray using the SIM card removal tool included in the box
Insert a nano SIM card (4FF size) and close the SIM tray
Connect the uplink for the Z4C device via a wired connection to connect to the Meraki cloud
Power on the Z4C and wait for the Z4C to show as online in the Meraki dashboard
Check with the carrier of choice if an APN needs to be configured. If so, do that from the Meraki Dashboard under Security & SD-WAN > Monitor > Appliance Status > Uplink tab
Navigate to Security & SD-WAN > 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
Test the cellular failover connection by unplugging the wired connection or by using the traceroute tool under Security & SD-WAN > Monitor > Appliance Status in the
Tools tab
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
A list of certified carriers can be found in our Z4/Z4C Overview and Specifications document
Please contact the Meraki Support team if the cellular connection is still not being recognized after following the steps above

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 Z4/Z4C 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 Z4/Z4C 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.
