2.2 Antennas and Ports
The Meraki MR84 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 MR84: MA-
ANT-20, MA-ANT-25, MA-ANT-27, and AIR-ANT2413P4M-N.
The Meraki MA-ANT-20 omni-directional antennas must be installed
vertically.
The Meraki MA-ANT-25 patch antenna, MA-ANT-27 dual-band sector
antenna, and Cisco AIR-ANT2513P4M-N stadium antenna must be installed
facing downward, at least 30 degrees from the horizon line.
2.3 Power Source Options
The MR84 access point can be powered using either an 802.3at capable
PoE switch or the Meraki 802.3at PoE injector (sold separately).

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 MR84 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 MR84 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 MR84 performs optimally immediately following installation,
Meraki recommends that you facilitate a firmware upgrade prior to
mounting your MR84.
1. Attach your MR84 to power and a wired Internet connection.
2.The MR84 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
MR84 to be able to seamlessly communicate with the Cloud Controller. The
most current list of outbound ports and IP addresses can be found here:
http://bit.ly/oZpMQ7
3.4 Assigning IP Addresses to MR84s
All gateway MR84s (MR84s 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 MR84 either through a PoE switch or a Meraki PoE Injector. If
using a PoE switch, plug an Ethernet cable into the MR84’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 MR84 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
“admin”. The default password is the AP’s serial number, with
hyphens included (e.g., Q2BD-551C-ZYW3).
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
- 802.3at PoE power source (either PoE switch or Meraki 802.3at PoE
Injector)
- Connection to the internet (if you are setting up your MR84 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 Installation Instructions
4.1 Choose Your Mounting Location

A good mounting location is important to getting the best performance out
of your MR84 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 MR84 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 MR84 for installation of all of your
chosen antennas.
4.2 Install the MR84
For most mounting scenarios, the MR84 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 MR84 to the mount plate.
4.2.1 Remove the Mount Plate from the Access Point
Before installing the mount plate, you must remove it from the back of the
access point.
