2.3 Security Features

The MR24 features multiple options for physically securing the access point after installation:

1.Security screw – The accessory kit includes screws that can be used to secure the access point to the mount plate. Engaging the security screw prevents accidental dislodging and theft.

2.Kensington lock – The access point contains a hard point that allows it to be secured to any nearby permanent structure using a standard Kensington lock.

2.4Ethernet Ports

Both MR24 and MR24 feature a Gigabit Ethernet RJ45 port that accepts 802.3af power (labeled “Eth0, PoE”). This port should be used for uplink to your WAN connection.

2.5 Power Source Options

The MR24 access point can be powered using either the Meraki AC Adapter or 802.3af PoE Injector (both sold separately) or a third-party 802.3af PoE switch.

2.6 Factory Reset Button

If the button is pressed and held for at least five seconds and then released, the MR24 will reboot and be restored to its original factory settings by deleting all configuration information stored on the unit.

2.7 LED Indicators and Run Dark Mode

Your MR24 is equipped with a series of LED lights on the front of the unit to convey information about system functionality and performance.

Signal Strength
One Light:	Fair
Four Lights:	Strongest
Moving Lights:	Searching for signal
Flashing Lights:	Error state. May indicate bad gateway or other routing fault
Radio Power
Off:	MR24 is off
Solid Orange:	MR24 is booting or trying to find a path to the internet
Solid Green:	MR24 is fully operational and connected to the network
Flashing Orange:	Firmware is upgrading
Flashing Green:	Error state. May indicate bad gateway or other routing fault
Ethernet
Off:	No active network connection at the Ethernet port
On:	Active network connection at the Ethernet port
Flashing:	Error state. May indicate bad gateway or other routing fault

The MR24 may be operated in “Run Dark” mode for additional security and to reduce the visibility of the access point. In this mode, the LEDs will not be illuminated. This mode may be enabled through Meraki Dashboard.

2.8 UL 2043 Plenum rating

The MR24 meets the UL 2043 plenum-rating standard. This certifies that the MR24 has adequate fire resistance and low smoke-emission characteristics to be mounted and operated in a building’s environmental air spaces, such as above suspended ceilings in an office environment.

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

The following is a brief overview only of the steps required to add an MR24 to your network. For detailed instructions about creating, configuring and managing Meraki wireless networks, refer to the Meraki Cloud Controller Manual (meraki.com/library/product).

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 if you ordered directly from Meraki) 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 Cloud Controller license key, which you should have received via email from [e-mail].

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.

3.2Check and Upgrade Firmware

To ensure your MR24 performs optimally immediately following installation, Meraki recommends that you facilitate a firmware upgrade prior to mounting your MR24.

1.Attach your MR24 to power and a wired Internet connection. See p. 19 of this Hardware Installation Guide for details.

2.The MR24 will turn on and the Power LED will glow solid orange. If the unit does not require a firmware upgrade, the Power LED will turn green within thirty seconds.

*If the unit requires an upgrade, the Power LED will begin blinking orange until the upgrade is complete, at which point the Power LED will turn solid green. You should allow about an hour for the firmware upgrade to complete, depending on the speed of your internet connection.

3.3Check 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 can be found here:

3.4 Assigning IP Addresses to MR24s

All gateway MR24s (MR24s 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 MR24 either through a PoE switch or a Meraki

PoE Injector. If using a PoE switch, plug an Ethernet cable into the MR24’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 MR24 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://my.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. Q2DD-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.

3.4.3 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 DHCP server. Through “DHCP reservations”, IP addresses are “reserved” for the MAC addresses of the Meraki APs. Please consult the documentation for the DHCP server to configure DHCP reservations.

3.5 Collect Tools

You will need the following tools to perform an installation:

T8 Torx	Phillips					Hammer	Drill with 1/4”
screwdriver	screwdriver						(6.3mm) bits

3.6 Collect Additional Hardware for Installation

or

802.3af PoE power source (either PoE	AC Adapter
switch or Meraki 802.3af PoE Injector)

Network cables with RJ45 connectors long enough for your particular mounting location

4 Installation Instructions

4.1 Choose Your Mounting Location

A good mounting location is important to getting the best performance out of your MR24 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 MR24 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 (meraki.com/library/product).

4.2Install the MR24

For most mounting scenarios, the MR24 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 MR24 to the mount plate.

4.2.1 Attach the Mount Plate

The MR24 mount plate can be used to install your access point in a wide range of scenarios: wall or solid ceiling, below a drop ceiling, on various electrical junction boxes, or above a drop ceiling (in the plenum). The mount plate contains a variety of hole patterns that are customized for each installation scenario. The mounting template (included inbox with mount plate) should be used to drill holes for wall mounts and also to identify the correct hole patterns in the mount plate that should be used for each type of mount.

The following images also show the hole patterns that should be used for each type of mount:
