Security Features
The MR52 and MR53 both feature 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
cradle. 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.
Ethernet Ports
The MR52 and MR53 both feature 2 Ethernet ports:
The labeled “PoE” accepts 802.3at and 802.3af power and should be used as the primary uplink to your AN/WAN.
5
The 2nd port may be used for ACP bonding with the PoE port
Link Aggregation
The second Ethernet port can be used in a bonded configuration with the "PoE" port. Ensure that the AP is
plugged into 2 switch ports on the same Ethernet switch that have been configured for ACP bonding. Keep in
mind that the maximum bonded aggregate bandwidth is 2.0 Gbps. See the MR ink Aggregation Configuration
Guide for more details
Power Source Options
The MR52 and MR53 access points can be powered using either the Meraki AC Adapter, PoE Injector (both
sold separately), or a third-party PoE switch.
Factory Reset Button
If the button is pressed and held for at least five seconds and then released, the AP will reboot and be restored to its
original factory settings by deleting all configuration information stored on the unit.
ED Indicators and Run Dark Mode
Your MR52 and MR53 are both equipped with a multi-color ED light on the front of the unit to convey information about
system functionality and performance:
• Orange - AP is booting (permanent Orange suggests hardware issue)
• 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 MR52 and MR53 both may be operated in “Run Dark” mode for additional security and to reduce the visibility of the
access point. In this mode, the ED will not be illuminated.
Keep in mind that only the primary uplink will draw PoE.
The MR52 and MR53 both will function in low power mode when powered by a 802.3af power source. While in
low power mode, the MR52 and MR53 both will disable its Air Marshal radio as well as three out of four transmit
streams on the 2.4 Ghz band. Despite being in low power mode, the device can still supply full 802.11ac
capabilities.

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 a MR52 or MR53 to your network. For detailed
instructions about creating, configuring and managing Meraki wireless networks, refer to the online documentation
(documentation.meraki.com).
1. ogin 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 MR52 or MR53 performs optimally immediately following installation, it is recommended that you
facilitate a firmware upgrade prior to mounting your AP.
1. Attach your AP to power and a wired Internet connection. See the "Power the Ap" section for details.
2. The AP will turn on and the ED will glow solid orange. If the unit does not require a firmware upgrade, the ED
will turn either green (no clients associated) or blue (clients associated) within thirty seconds.
* If the unit requires an upgrade, the ED will begin blinking orange until the upgrade is complete, at which point the ED
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
All gateway MR52s and MR53s (An AP with Ethernet connections to the AN) must be assigned routable IP addresses.
These IP addresses can be dynamically assigned via DHCP or statically assigned.
7
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.
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 AP either through a PoE switch or a PoE
Injector. If using a PoE switch, plug an Ethernet cable into the AP’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 AP to the “PoE” port of the Injector, and the client machine to the “ AN” 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. og 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 AN.
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.

Choose Your Mounting ocation
A good mounting location is important to getting the best performance out of your 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 AP should have line of sight to at least two other Meraki devices. A Cisco
Partner can help ensure that your AP placement is ideal.
Install the AP
For most mounting scenarios, the MR52/53 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 AP to the mount cradle.
Attach the mount cradle
The MR52/53 mount cradle 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.
The mount cradle contains a variety of hole patterns that are customized for each installation scenario. The mounting
template (included inbox with mount cradle) should be used to drill holes for wall mounts and also to identify the correct
hole patterns in the mount cradle that should be used for each type of mount. The included mount cradle
template shows the hole patterns that should be used for each type of mount.
Wall or Solid Ceiling Mount Using mount cradle
Using included wall anchors and screws, attach the mount cradle to your mounting wall or ceiling. It is
recommended that the AP be mounted to a wall or solid ceiling using the mount cradle for physical security
reasons.
Drop ceiling mount using mount cradle
To mount your AP on a drop ceiling T-rail, use the included drop ceiling mounting accessory kit. The accessory kit
can be used to mount to most 9/16”, 15/16” or 1 ½” T-rails. The kit contains:
• Drop ceiling mounting clips with set screws
