2 MR52 Overview
The Meraki MR52 is an enterprise-class, dual-concurrent 4x4 MIMO 802.11ac indoor access point designed for
high-density deployments in offices, schools, hospitals and hotels. When connected to the Meraki Cloud Control
ler, the MR52 enables the creation of ultra-high speed, reliable indoor wireless networks quickly, easily and cost-
effectively.
2.1 Package Contents

2.3 Security Features
The MR52 features multiple options for physically securing the access point after installation:
1. Security screw – The accessory kit includes screws that can be used to secure the access point to
the mount plate. Engaging the security screw prevents accidental dislodging and theft.
2. Kensington lock – The access point contains a hard point that allows it to be secured to any nearby
permanent structure using a standard Kensington lock.
2.4 Ethernet Ports
The MR52 features a Gigabit Ethernet RJ45 port that accepts 802.3at power (labeled “PoE”). This port should
be used for uplink to your WAN connection.
2.5 Power Source Options
The MR52 access point can be powered using either the Meraki AC Adapter or 802.3at PoE Injector (both sold
separately) or a third-party 802.3at PoE switch.
2.6 Factory Reset Button
If the button is pressed and held for at least five seconds and then released, the MR52 will reboot and be
restored to its original factory settings by deleting all configuration information stored on the unit.

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:

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.
