• Power off the unit before you begin. Read the installation instructions before connecting the system to the power
source.
• Before you work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with
standard practices for preventing accidents.
• Read the wall-mounting instructions carefully before beginning installation. Failure to use the correct hardware or to
follow the correct procedures could result in a hazardous situation to people and damage to the system.
• 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 or standard PoE to ensure regulatory compliance.
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 MR76 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. o 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 MR76 performs optimally immediately following installation, it is recommended that you facilitate a firmware upgrade prior to mounting your
MR76.
1. Attach your MR76 to PoE enabled wired Internet connection. See the "Power the MR76" section for details.
2. The MR76 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.
Assigning IP Addresses to MR76s
All gateway MR76s (MR76s with Ethernet connections to the LAN) must be assigned routable IP addresses. These IP addresses can be dynamically assigned
via DHCP or statically assigned.
Dynamic Assignment (Recommended)
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.
7
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 MR76 either through a PoE switch or a PoE
Injector. If using a PoE switch, plug an Ethernet cable into the MR76’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 MR76 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
DHCP server. Through “DHCP reservations,” IP addresses are “reserved” for the MAC addresses of the Meraki APs. Please consult the documentation
for the DHCP server to configure DHCP reservations.

Collect Additional Hardware for Installation
You will need the following tools to perform an installation:
• Network cables with RJ45 connectors long enough for your particular mounting location
• 802.3af PoE power source (either PoE switch or Meraki PoE Injector)
• Connection to the internet (if you are setting up your MR76 as a gateway to the internet)
• Appropriately sized metal straps (if mounting to a pole larger than 3.9” in diameter)
• Specialized mounting hardware if mounting to surface other than wood, stucco or stone
Installation Instructions
Warning: Due to the heat dissipation in the back of APs during normal operation, please do not stack powered on APs on top of each other during
pre-installation to avoid heat damage.

Choose Your Mounting Location
A good mounting location is important to getting the best performance out of your MR76 access point. Keep the following in mind:
1. The device should have unobstructed line of sight to most coverage areas.
2. Power over Ethernet supports a maximum cable length of 300 ft (100 m).
3. If being used in a mesh deployment, the MR76 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 MR76 for
installation of all of your chosen antennas.
Install the MR76
For most mounting scenarios, the MR76 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 MR76 to the mount cradle.
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 MR76 mount plate can be used to install your access point in a wide range of scenarios.
