2 MR84 Overview

The Meraki MR84 is an enterprise-class, 802.11abgn/ac outdoor access

point designed for rugged environments. When connected to the Meraki

Cloud Controller, the MR84 enables the creation of high-speed and reliable

networks that cover large outdoor and industrial areas quickly, easily, and

cost-effectively.

The Meraki MR84 has an operating temperature of -40oto 60oC.

2.1 Package Contents

The MR84 package contains the following:

- MR84 access point

- Wall screws & anchors

- Mounting plate

- Cable glands

- Mounting straps

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).

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 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.

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.

4.2.2 Attach the Mount Plate

The MR84 mount plate can be used to install your access point in a wide

range of scenarios.

4.2.2.1 Wall or Solid Ceiling Mount Using Mount Plate

Using included wall anchors and screws, attach the mount plate to your

mounting wall or ceiling.

It is recommended that the MR84 be mounted to a wall or solid ceiling

using the mount plate for physical security reasons.

4.2.2.2 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.

4.2.3 Mount the MR84

Insert the posts on the mount plate into the attachment slots on the access

point.

4.2.3.1 Attach Antennas

Remove protective plastic covers from all four N-type RF connectors. Attach

appropriate antennas (and protective boots if included).

4.2.3.2 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.

4.2.3.3 Powering the MR84 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

Ethernet port in the bay of the MR84.

For more details, see Meraki 802.3at Power Over Ethernet Injector

datasheet.

4.2.3.4 Powering the MR84 with an 802.3at Power over Ethernet Switch

Route Ethernet cable from a port on an active 802.3at PoE switch to the

Ethernet port in the bay of the MR84.

The MR84 is Gigabit Ethernet-capable. To maximize device performance, a

Gigabit Ethernet-capable switch should be used.

4.2.3.5 Attach Power over Ethernet to the MR84

1. Remove the dust cover from the Ethernet port of the MR84.

Unscrew it with a coin or flathead screwdriver.

2. Route the Ethernet cable from the PoE Injector “OUT” port to the

MR84.

3. Install a cable gland on the MR84 end of the cable.

4. Plug the Ethernet cable into the Ethernet port of the Meraki MR84.

a. Connect the cable to the Ethernet port on the MR84.

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.

Optional: Make the MR84 a gateway

1. Connect an active internet connection to the “IN” port of the PoE injector.

4.2.3.6 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.

4.4 Verify Device Functionality and Test Network

Coverage

1. Check LEDs The Radio Power LED should be solid white. If it is cycling

rainbow, the firmware is automatically upgrading and the LED should

turn white when the upgrade is completed (normally in under thirty

minutes).

2.Note: Your MR84 must have an active route to the Internet to check and

upgrade its firmware.

3.Verify access point connectivity Use any 802.11 client device to connect

to the MR84 and verify proper connectivity using the client’s web

browser.

4.Check network coverage 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.
