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
The following is a brief overview only of the steps required to add an MR52 to your network. For detailed
instructions about creating, configuring and managing Meraki wireless networks, refer to the Meraki Cloud
Controller Manual (meraki.com/library/product).
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 if you
ordered directly from Meraki) 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 Cloud Controller license key, which you
should have received via email from [email protected].
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.
3.2 Check and Upgrade Firmware
To ensure your MR52 performs optimally immediately following installation, Meraki recommends that you
facilitate a firmware upgrade prior to mounting your MR52.
1. Attach your MR52 to power and a wired Internet connection. See p. 19 of this Hardware Installation
Guide for details.
2. The MR52 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 white 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 white. 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 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 can be found here:
http://tinyurl.com/y79une3

9
3.4 Assigning IP Addresses to MR52s
All gateway MR52s (MR52s 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 MR52 either through a PoE switch or a Meraki
PoE Injector. If using a PoE switch, plug an Ethernet cable into the MR52’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 MR52 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
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.
3.4.3 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.

4 Installation Instructions
4.1 Choose Your Mounting Location
A good mounting location is important to getting the best performance out of your MR52 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 MR52 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 (meraki.com/library/product).
4.2 Install the MR52
For most mounting scenarios, the MR52 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 MR52 to the mount plate.
4.2.1 Attach the Mount Plate
The MR52 mount plate can be used to install your access point in a wide range of scenarios: wall or solid
ceiling, below a drop ceiling, on various electrical junction boxes, or above a drop ceiling (in the plenum).
The mount plate contains a variety of hole patterns that are customized for each installation scenario. The
mounting template (included inbox with mount plate) should be used to drill holes for wall mounts and also to
identify the correct hole patterns in the mount plate that should be used for each type of mount.
The following images also show the hole patterns that should be used for each type of mount:
