• MR72 Cloud-Managed Access Point

• Mount cradle

• Wall screws

• Wall screw anchors

• Grounding screws

• Mounting straps

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)

• 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.

The Vent

The vent allows pressure equalization between the interior and the environment. This prevents internal condensation

and maintains a waterproof seal.

The mount cradle has the following features:

Mounting posts (4x)

The mounting slots located in the middle of the mounting plate marry the MR72 to the mounting plate.

Mounting holes (4x)

The mounting holes located on the 4 outermost corners of the mounting plate allow secure installation of the mounting

plate to a surface such as a wall.

Vertical orientation mounting strap slots (2x)

The vertical orientation mounting strap slots located in the middle of the mounting plate secure the mounting plate to a

vertical pole using the included mounting straps.

Horizontal orientation mounting strap slots (2x)

The horizontal orientation mounting strap slots located in the middle of the mounting plate secure the mounting plate to

a horizontal pole using the included mounting straps.

Release tab

The release tab located at the bottom of the mounting plate. It locks the movement of the AP once attached.

Mount plate attachment screw

The mount plate attachment screw is located at the bottom of the mounting plate. It securely attaches the AP to the

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.

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:

Collect Additional ardware 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 or 802.3at PoE power source (either PoE switch or Meraki PoE Injector)

• Connection to the internet (if you are setting up your MR72 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

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.

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

Connect one end of grounding strap to grounding post with included screw and washer. Securely attach the other end

nearby metal structure.

Mount the MR72

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.

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.

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.
