2 MR74 Overview
The Meraki MR74 is an enterprise-class, 802.11abgn/ac AP outdoor
designed for rugged environments. When connected to the Meraki Cloud
Controller, the MR74 enables the creation of high-speed and reliable
networks that cover large outdoor and industrial areas quickly, easily, and
cost-effectively.
The Meraki MR74 has an operating temperature of -40o to 60o C.
2.1 Package Contents
The MR74 package contains the following:
- MR74 access point
-Wall screws & anchors
-Mounting plate
-Cable gland
-Mounting straps
2.2 Antennas and Ports
The Meraki MR74 has two radios. Each radio has two external antenna
connectors; both connectors for a particular radio should be attached to
the same type of antenna. The 5 GHz radio is used for mesh or client
communication. The 2.4 GHz radio is primarily used for client
communication. However, it can also communicate with Meraki 2.4 GHz
access points.

Meraki offers a number of different antennas for use with the MR74: MA-
ANT-20, MA-ANT-21, MA-ANT-23, MA-ANT-25, MA-ANT-27, and Cisco
AIR-ANT2513P4M-N.
The Meraki MA-ANT-20 omni-directional antennas must be installed
vertically.
The Meraki MA-ANT-21, MA-ANT-23, MA-ANT-25, MA-ANT-27, and
Cisco AIR-ANT2513P4M-N antennas must be installed facing downward,
at least 30 degrees from the horizon line.
2.3 Power Source Options
The MR74 access point can be powered using either an 802.3af capable
PoE switch or the Meraki 802.3af PoE injector (sold separately).
2.4 LED Indicators and Run Dark Mode

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
Meraki recommends that you add your MR74 to a network in Dashboard
before mounting it in the field. The following is a brief overview only of the
steps required to add an MR74 to your network. For detailed instructions
about creating, configuring and managing Meraki wireless networks, refer
to the Meraki Cloud Controller Manual
(cisco.meraki.com/support/#documentation).
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 nodes or create a new
network.
3.Add your nodes 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 node, which looks like Qxxx-xxxx-xxxx,
and is found on the bottom of the unit.
4.Finally, go to the map / floor plan view and place each node on the map
by clicking and dragging it to the location where you plan to mount it.
You can always modify the location later.
3.2 Check and Upgrade Firmware
To ensure your MR74 performs optimally immediately following
installation, Meraki recommends that you facilitate a firmware upgrade
prior to mounting your MR74.
1. Attach your MR74 to power and a wired Internet connection.
2.The MR74 will turn on and the LED will glow solid orange. If the unit
does not require a firmware upgrade, the LED will turn solid white

within 30 seconds.
* If the unit requires an upgrade, the LED will cycle rainbow 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 your network will be located behind a firewall, it must allow outgoing
connections on particular ports to particular IP addresses in order for the
MR74 to be able to seamlessly communicate with the Cloud Controller. The
most current list of outbound ports and IP addresses can be found here:
https://documentation.meraki.com/zGeneral_Administration/Other_Top
ics/Firewall_Rules_for_Cloud_Connectivity
3.4 Assigning IP Addresses to MR74s
All gateway MR74s (MR74s 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 MR74 either through a PoE switch or a Meraki PoE Injector. If
using a PoE switch, plug an Ethernet cable into the MR74’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 MR74 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://ap.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 the AP’s serial number, with hyphens included (e.g., Q2BD-551C-
ZYW3), and the default password is blank.
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.
3.5 Collect Tools
You will need the following tools to perform an installation:
-Flat-head screwdriver
-Drill with appropriate bits for mounting wall anchors (if mounting to a
wall)
-Phillips screwdriver
- Tin snips(if mounting with hose clamps)
-Power screwdriver with 5/16”(8 mm) nut driver, Phillips & flat heads
(recommended)
3.6 Collect Additional Hardware for Installation
-Network cables with RJ45 connectors long enough for your particular
mounting location
-802.3af PoE power source (either PoE switch or Meraki 802.3af PoE
Injector)

-Connection to the internet (if you are setting up your MR74 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
-Laptop with wireless to verify setup (recommended)
4 InstallationInstructions
4.1 Choose Your Mounting Location
A good mounting location is important to getting the best performance out
of your MR74 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 MR74 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 (cisco.meraki.com/support/#documentation).
4.The antennas should be as unobstructed as possible. Make sure that
there is clearance around the MR74 for installation of all of your
chosen antennas.

2. Professional Installation Requirements
The following requirements for installation and operation of outdoor systems must be
addressed:
Operation in the 5600-5650-MHz band is not authorized for 5-GHz WLAN systems,
whether operating indoors or outdoors. This does not pose a problem for Cisco®WLAN
since this band is not accessible for Cisco products.
Use of indoor-only equipment outdoors can lead to FCC enforcement action, such as
fines or requirements to disable the system. This includes installations where the
access point is placed indoors and the antenna is placed outdoors, as well as
installations involving retractable roofs (for example, football stadiums).
For WLAN systems being installed outdoors, the following requirements must be
met.
a) Systems must be professionally installed by a qualified engineer familiar
with WLAN, including Cisco trained partners and resellers.
b) Operation in the 5600-5650-MHz band is prohibited.
c) It is recommended that the installer register the installation of their system in
the Wireless Internet Service Providers Association (WISPA database). This is
especially important for systems that are installed within 35 km of the FAA TDWR.

(Please see the links later in this document to WISPA database with TDWR
locations.)
d) When within 35 km distance of a TDWR, the center frequency of the WLAN
must be separated from the TDWR center frequency by 30 MHz.
a. If the radar is operating from 5600-5610 MHz, disable the use of channel
116 (5580 MHz).
b. If the radar is operating from 5630-5650 MHz, disable the use of channel
132 (5660 MHz).
Note: Cisco will be disabling channels 116 and 132 for outdoor systems in the
future, the instructions in (d) only applies to systems that currently have the
channels enabled.
e) Additional mitigation techniques can include first, not orienting the antennas
in the main beam of the weather radar, and second, ensuring that the antenna is not
positioned in line-of-sight of the FAA TDWR.
f) Verify that the antennas used are approved for use with Cisco WLAN systems.
Installers or operators using non-approved antennas or making any unauthorized
changes may be subject to enforcement action.
g) Operation in the 5150-5250MHz is restricted to indoor use only.
