3 Pre-Install Preparation
You should complete the following steps before going on-site to perform an installation.
3.1 Configure Your Network in Dashboard
Meraki recommends that you add your MR66 to a network in Dashboard before mounting it in the field. The
following is a brief overview only of the steps required to add an MR66 to your network. For detailed
instructions about creating, configuring and managing Meraki wireless networks, refer to the Meraki Cloud
Controller Manual (
meraki.com/support/#documentation).
1. Login to
2. Find the network to which you plan to add your nodes or create a new network.
3. Add your nodes to your network. You will need your Meraki order number (found on your invoice if you
ordered directly from Meraki) or the serial number of each node, which looks like Qxxx-xxxx-xxxx, and is
found on the bottom of the unit.
4. Finally, go to the map / floor plan view and place each node on the map by clicking and dragging it to
the location where you plan to mount it. You can always modify the location later.
http://dashboard.meraki.com. If this is your first time, create a new account.
3.2 Check and Upgrade Firmware
To ensure your MR66 performs optimally immediately following installation, Meraki recommends that you
facilitate a firmware upgrade prior to mounting your MR66.
1. Attach your MR66 to power and a wired Internet connection. See p. 19 of this document for details.
2. The MR66 will turn on and the Power LED will glow solid orange. If the unit does not require a firmware
upgrade, the Power LED will turn green within thirty seconds.
* If the unit requires an upgrade, the Power LED will begin blinking orange until the upgrade is complete,
at which point the Power LED will turn solid green. You should allow about an hour for the firmware
upgrade to complete, depending on the speed of your internet connection.
3.3 Check and Configure Firewall Settings
If your network will be located behind a firewall, it must allow outgoing connections on particular ports to
particular IP addresses in order for the MR66 to be able to seamlessly communicate with the Cloud Controller.
The most current list of outbound ports and IP addresses can be found here:
http://bit.ly/oZpMQ7
10
Page 10
3.4 Assigning IP Addresses to MR66s
All gateway MR66s (MR66s with Ethernet connections to the LAN) must be assigned routable IP addresses.
These IP addresses can be dynamically assigned via DHCP or statically assigned.
3.4.1 Dynamic Assignment
When using DHCP, the DHCP server should be configured to assign a static IP address for each MAC address
belonging to a Meraki AP. Other features of the wireless network, such as 802.1X authentication, may rely on the
property that the APs have static IP addresses.
3.4.2 Static Assignment
Static IPs are assigned using the local web server on each AP. The following procedure describes how to set
the static IP:
1. Using a client machine (e.g., a laptop), connect to the AP either wirelessly (by associating to any SSID
broadcast by the AP) or over a wired connection.
If using a wired connection, connect the client machine to the MR66 either through a PoE switch or a Meraki
PoE Injector. If using a PoE switch, plug an Ethernet cable into the MR66’s Ethernet jack, and the other end
into a PoE switch. Then connect the client machine over Ethernet cable to the PoE switch. If using a Meraki
PoE Injector, connect the MR66 to the “PoE” port of the Injector, and the client machine to the “LAN” port.
2. Using a web browser on the client machine, access the AP’s built-in web server by browsing to
http://my.meraki.com. Alternatively, browse to http://10.128.128.128.
3. Click on the “Static IP Configuration” tab. Log in. The default user name is “admin”. The default password is
the AP’s serial number, with hyphens included (e.g., Q2BD-551C-ZYW3).
4. Configure the static IP address, net mask, gateway IP address and DNS servers that this AP will use on its
wired connection.
5. If necessary, reconnect the AP to the LAN.

4 Installation Instructions
4.1 Choose Your Mounting Location
A good mounting location is important to getting the best performance out of your MR66 access point.
Keep the following in mind:
1. The device should have unobstructed line of sight to most coverage areas. For example, if installing
in an office filled with workspaces divided by mid-height cubicle walls, installing on the ceiling or high
on a wall would be ideal.
2. Power over Ethernet supports a maximum cable length of 300 ft (100 m).
3. If being used in a mesh deployment, the MR66 should have line of sight to at least two other Meraki
devices. For more detailed instructions regarding access point location selection, reference the Meraki
Network Design Guide (
4. The antennas should be as unobstructed as possible. Make sure that there is clearance around the
MR66 for installation of all of your chosen antennas.
meraki.com/support/#documentation).
4.2 Install the MR66
For most mounting scenarios, the MR66 mount plate provides a quick, simple, and flexible means of mounting
your device. The installation should be done in two steps. First, install the mount plate to your selected location.
Then attach the MR66 to the mount plate.

4.4 Verify Device Functionality and Test Network Coverage
1. Check LEDs
The Radio Power LED should be solid green. If it is flashing orange, the firmware is automatically upgrading and the
LED should turn green when the upgrade is completed (normally in under thirty minutes). If the device is a gateway,
the Ethernet LED and the four Signal Strength LEDs should be green as well. If the device is a repeater only, the
Ethernet LED will not be illuminated and the number of green Signal Strength LEDs will show the signal strength to
the nearest Meraki device. See section 2.6 for further details about information conveyed by the LEDs.
Note: Your MR66 must have an active route to the Internet to check and upgrade its firmware.
2. Verify access point connectivity
Use any 802.11 client device to connect to the MR66 and verify proper connectivity using the client’s web
browser.
3. Check network coverage
Confirm that you have good signal strength throughout your coverage area. You can use the signal strength meter
on a laptop, smart phone, or other wireless device.
