installation guides section on our documentation website.

Product Overview

Physical Specifications

MR44

Interfaces

• 1x 100/1000/2.5G BASE-T Ethernet (RJ45)

• 1x DC power connector (5.5 mm x 2.5 mm, center positive)

Power

•Power over Ethernet: 42.5 - 57 V (802.3at) or 37 - 57 V (802.3af) - low power mode **

• Alternative: 12 V DC input

•Power consumption: 30W max (802.3at) or 15W max (802.3af) - low power mode **

• Power over Ethernet injector and DC adapter sold separately

In low power mode, MR44 will do the following:

1. Downshift its Ethernet uplink speed from 2.5 Gbps to 1 Gbps

2. Transition from 4x4:4 to 2x2:2 in 5G z

3. Disable its dedicated IoT (previously known as BLE) radio

4. Reduce the max Tx power

Warning: Please ensure that MR44 is connected to an 802.3at-capable (PoE+) switch/

power injector during the initial installation OR ensure that the network MR44 is added to is set

to MR 27.6 firmware (not yet available at the time of writing) or newer firmware.

This is because the default MR44 firmware image has support for the low-power mode,

however, MR 27.5/27.5.1 or lower firmware does not have low power mode support. Using

802.3af switch/power injector with MR44 set to 27.5/27.5.1 or lower firmware might result in

unexpected behaviors including but not limited to reboots or degraded performance.

Due to the reasons stated above, please do not downgrade the network with MR44 APs to 27.5/

27.5.1 or lower firmware if they are being powered on by 802.3af (PoE) switch/power injector.

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.

LED Indicators and Run Dark Mode

Your access point is equipped with a multi-color LED 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

NOTE: Blinking Green LED indicates that the device is in site survey mode. Please see the Conducting Site Surveys

with MR Access Points for more details.

The MR44 access point may be operated in the “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.

Package Contents

The access point packages contain the following:

MR44 Cloud-Managed Access Point

Mount cradle including built-in level tool

Drop ceiling mount kit

Wall screws, wall screw anchors, and security screws

Safety and Warnings

These operations are to be taken with respect to all local laws. Please take the following into consideration for safe

operation:

• Power off the unit before you begin. Read the installation instructions before connecting the system to the power

source.

• Before you work on any equipment, be aware of the hazards involved with electrical circuitry, and be familiar with

standard practices for preventing accidents.

• Read the wall-mounting instructions carefully before beginning installation. Failure to use the correct hardware or to

follow the correct procedures could result in a hazardous situation to people and damage to the system.

• This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that the protective

device is rated not greater than 15 A, 125 Vac, or 10A, 240 Vac.

• Please only power the device with the provided power cables or standard PoE to ensure regulatory compliance.

Pre-install Preparation

You should complete the following steps before going on-site to perform an installation.

Configure your Dashboard Network

The following is a brief overview only of the steps required to add an access point to your network. For detailed

instructions about creating, configuring, and managing Meraki wireless networks, refer to the online documentation

(documentation.meraki.com).

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 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 Set Firmware

To ensure your access point 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 "Getting Power to the AP" section for details.

2. The AP 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 orange 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 Upstream 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 on the firewall configuration

page in your dashboard.

Assigning an IP Address

All gateway APs (An AP 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:

• 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.

• 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 “LAN” port.

• 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.

• 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).

• Configure the static IP address, net mask, gateway IP address and DNS servers that this AP will use on its wired

connection.

• 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:

T8 Torx Screwdriver, Phillips screwdriver, Hammer, Drill with 1/4" (6.3mm) bits

Collect Additional Hardware for Installation

You will need the following hardware to perform an installation:

802.3at PoE Power Source (either PoE switch or Meraki 802.3at PoE Injector) or an AC adaptor and network cables

with RJ45 connectors long enough for your particular mounting location

Installation Instructions

Warning: Due to the heat dissipation in the back of APs during normal operation, please do not stack powered on APs

on top of each other during pre-installation to avoid heat damage.

Choose Your Mounting Location

A good mounting location is important to get the best performance out of your access point. Keep the following in mind:
