Understanding the MR72
Your Meraki MR72 has the following features:
LED indicator
Your MR72 is equipped with a multi-color LED light on the bottom edge of the unit to convey information about system
functionality and performance:
• Orange - AP is booting (permanent Orange suggests hardware issue)
1
• Rainbow - AP is initializing/scanning
• Blinking Blue - AP is upgrading
• Green - AP in Gateway mode with no clients
• Blue - AP in Gateway mode with clients
• Blinking Orange - AP can't find uplink
The MR72 may be operated in “Run Dark” mode for additional security and to reduce the visibility of the access point. In
this mode, the LED will not be illuminated. This mode may be enabled through the Meraki dashboard.
Ethernet Port
The MR72 features a Gigabit Ethernet RJ45 port that accepts 802.3af power. This port should be used for uplink to your
WAN connection.
N-Type antenna attachement ports (4x)
2x N-Type antenna ports are located at the top of the MR72 and 2x are located at the bottom of the MR72. The pairs of
antenna ports each correspond to the 2 client serving radios. The spectrum that each pair serves is printed on the shell
of the MR72.
Mount plate attachment slots (4x)
The mounting slots located on the rear shell of the MR72 marry to the 4 mounting posts on the mounting plate, securely
fastening the MR72 to the mounting plate.
Factory reset button
The factory reset button is located in a small pin-sized hole just above the Ethernet port of the MR72. If the button is
pressed and held for at least five seconds and then released, the MR72 will reboot and be restored to its original factory
settings by deleting all configuration information stored on the unit.

mounting plate.
Mount plate grounding post
The mount plate grounding post located on the left side of the mounting plate. Using the included grounding strap, the
ground post allows you to ground the unit.
Pre-Install Preparation
You should complete the following steps before going on-site to perform an installation.
Configure Your Network in Dashboard
The following is a brief overview only of the steps required to add an MR72 to your network. For detailed instructions
about creating, configuring and managing Meraki wireless networks, refer to the online documentation
(documentation.meraki.com/mr).
1. Login to http://dashboard.meraki.com. If this is your first time, create a new account.
2. Find the network to which you plan to add your APs or create a new network.
3. Add your APs to your network. You will need your Meraki order number (found on your invoice) or the serial
number of each AP, 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.
4. Go to the map / floor plan view and place each AP on the map by clicking and dragging it to the location where you
plan to mount it.
Check and Upgrade Firmware
To ensure your MR72 performs optimally immediately following installation, it is recommended that you facilitate a
firmware upgrade prior to mounting your MR72.
1. Attach your MR72 to power and a wired Internet connection. See the "Power the MR72" section for details.
2. The MR72 will turn on and the LED will glow solid orange. If the unit does not require a firmware upgrade, the LED
will turn either green (no clients associated) or blue (clients associated) within thirty seconds.
* If the unit requires an upgrade, the LED will begin blinking blue until the upgrade is complete, at which point the LED
will turn solid green or blue. 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 Firewall Settings
If a firewall is 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 here.
4
Assigning IP Addresses to MR72s
All gateway MR72s (MR72s with Ethernet connections to the LAN) must be assigned routable IP addresses. These IP
addresses can be dynamically assigned via D CP or statically assigned.
Dynamic Assignment
When using D CP, the D CP 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.
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 wirelessly (by associating to any SSID broadcast by the
AP) or over a wired connection.
2. If using a wired connection, connect the client machine to the MR72 either through a PoE switch or a PoE Injector.
If using a PoE switch, plug an Ethernet cable into the MR72’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 PoE Injector, connect the MR72
to the “PoE” port of the Injector, and the client machine to the “LAN” port.
3. 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.
4. Click on the “Uplink Configuration” tab. Log in. The default login is the serial number (e.g. Qxxx-xxxx-xxxx), with no
password (e.g., Q2DD-551C-ZYW3).
5. Configure the static IP address, net mask, gateway IP address and DNS servers that this AP will use on its wired
connection.
6. If necessary, reconnect the AP to the LAN.
Static IP via DHCP Reservations
Instead of associating to each Meraki AP individually to configure static IP addresses, an administrator can assign static
IP addresses on the upstream D CP server. Through “D CP reservations,” IP addresses are “reserved” for the MAC
addresses of the Meraki APs. Please consult the documentation for the D CP server to configure D CP reservations.
Collect Tools
You will need the following tools to perform an installation:

• Specialized mounting hardware if mounting to surface other than wood, stucco or stone
Installation Instructions
Choose Your Mounting Location
A good mounting location is important to getting the best performance out of your MR72 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 MR72 should have line of sight to at least two other Meraki devices.
4. The antennas should be as unobstructed as possible. Make sure that there is clearance around the MR72 for
installation of all of your chosen antennas.
Install the MR72
For most mounting scenarios, the MR72 mount cradle provides a quick, simple, and flexible means of mounting your
device. The installation should be done in two steps. First, install the mount cradle to your selected location. Then,
attach the MR72 to the mount cradle.
6
Remove the Mount Plate from the Access Point
Before installing the mount plate, you must remove it from the back of the access point.
1. Unscrew the mount plate attachment screw.
2. Lift the mount plate release tab upwards.
3. While holding the mount plate release tab up, slide the mount plate off the access point in the direction shown
below.
Attach the mount cradle
The MR72 mount plate can be used to install your access point in a wide range of scenarios.
all or Solid Ceiling Mount Using mount cradle
Using included wall anchors and screws, attach the mount plate to your mounting wall or ceiling.
It is recommended that the MR72 be mounted to a wall or solid ceiling using the mount plate for physical security
reasons.
Pole Mount Using Mount Plate
Use the included mounting straps to mount the AP to a pole less than 3.9” in diameter. Thread the mounting straps
through the mounting strap slots to secure the mount plate in a horizontal or vertical orientation.
Attach Grounding Strap

Attach the MR72 to the Mount Cradle
Insert the posts on the back of the access point into the attachment slots on the mount plate.
Aim Antennas
If you are using directional antennas, aim them appropriately to ensure optimal performance for your specific network
topography. Omnidirectional antennas perform best in a mesh network when oriented vertically.
8
Attach Antennas
Remove protective plastic covers from all four N-type RF connectors. Attach appropriate antennas (and protective boots
if included).
Power the MR72
1. Route the Ethernet cable from the PoE Injector “OUT” port or from a PoE enabled switch to the MR72.
2. Install a Cable Gland on the MR72 end of the cable.
3. Plug the Ethernet cable into the Ethernet port of the Meraki MR72.
a. Connect the cable to the Ethernet port on the MR72.
b. Screw the gland body into the threaded hole of the port. Use an adjustable wrench to make sure the gland
body is fully seated in the hole.
c. Insert the split ring gasket into the gland body.
d. Screw the cap tightly onto the gland. You may need a wrench to fully tighten the cap, but take care not to
damage the cable in the process.
Powering the MR72 with the Meraki 802.3at Power over Ethernet Injector (sold separately)
1. Plug the power cord into the PoE Injector and the other end into wall power.
2. Plug an Ethernet cable that is connected to an active Ethernet connection into the “IN“ port on the injector.
3. Route Ethernet cable from the “OUT“ port on the injector to the Eth0 port in the cable bay of the MR72.
9
Powering the MR72 with an 802.3af Power over Ethernet Switch
Route Ethernet cable from a port on an active 802.3af PoE switch to the Eth0 port in the bay of the MR72. The MR72 is
Gigabit Ethernet-capable. To maximize device performance, a Gigabit-capable switch should be used.
Verify Device Functionality and Test Network Coverage
1. Check LEDs
a. The Power LED should be solid green (or blue, if clients are connected). If it is flashing blue, the firmware is
automatically upgrading and the LED should turn green when the upgrade is completed (normally within a
few minutes). See the "LED Indicators" section for more details. .
b. Note: Your MR72 must have an active route to the Internet to check and upgrade its firmware.
2. Verify access point connectivity
a. Use any 802.11 client device to connect to the MR72 and verify proper connectivity using the client’s web
browser.
3. Check network coverage
4. 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.
