A mounting template is included with the mounting plate to assist with the install.

Security Features

The MR32 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 cradle. 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.

Ethernet Ports 

The MR32 features a Gigabit Ethernet RJ45 port that accepts 802.3at and 802.3af power (labeled “Eth0 + PoE”). This port should be used for uplink to your WAN connection.

Power Source Options

The MR32 access point can be powered using either the Meraki AC Adapter, PoE Injector (both sold separately), or a third-party PoE switch.

Factory Reset Button

If the button is pressed and held for at least five seconds and then released, the MR32 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 MR32 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 

The MR32 may be operated in “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.

UL 2043 Plenum rating

The MR32 meets the UL 2043 plenum-rating standard. This certifies that the MR32 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.

Pre-Install Preparation

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

Configure Your Network in Dashboard

The following is a brief overview only of the steps required to add an MR32 to your network. For detailed instructions about creating, configuring and managing Meraki wireless networks, refer to the online documentation (documentation.meraki.com/mr).

  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 Enterprise 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 Upgrade Firmware

To ensure your MR32 performs optimally immediately following installation, it is recommended that you facilitate a firmware upgrade prior to mounting your MR32.

  1. Attach your MR32 to power and a wired Internet connection. See the "Power the MR32" section for details.
  2. The MR32 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 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 here

Assigning IP Addresses to MR32s

All gateway MR32s (MR32s with Ethernet connections to the LAN) must be assigned routable IP addresses. These IP addresses can be dynamically assigned via DHCP or statically assigned.

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.

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 wirelessly (by associating to any SSID broadcast by the AP) or over a wired connection.
  2. If using a wired connection, connect the client machine to the MR32 either through a PoE switch or a PoE Injector. If using a PoE switch, plug an Ethernet cable into the MR32’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 MR32 to the “PoE” port of the Injector, and the client machine to the “LAN” port.
  3. 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.
  4. 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).
  5. Configure the static IP address, net mask, gateway IP address and DNS servers that this AP will use on its wired connection.
  6. 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 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.

Installation Instructions

Choose Your Mounting Location

A good mounting location is important to getting the best performance out of your MR32 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 MR32 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.cisco.com/library/).

In some cases a firmware update is required to enable mesh on a new MR32. Connect your MR32 to a wired uplink to complete the automatic firmware update which will ensure an easy mesh install.

Install the MR32

For most mounting scenarios, the MR32 mount cradle provides a quick, simple, and flexible means of mounting your device. The installation should be done in two steps. First, install the mount cradle to your selected location. Then, attach the MR32 to the mount cradle.

Attach the mount cradle

The MR32 mount cradle 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 cradle contains a variety of hole patterns that are customized for each installation scenario. The mounting template (included inbox with mount cradle) should be used to drill holes for wall mounts and also to identify the correct hole patterns in the mount cradle that should be used for each type of mount. The included mount cradle template shows the hole patterns that should be used for each type of mount.

Wall or Solid Ceiling Mount Using mount cradle

Using included wall anchors and screws, attach the mount cradle to your mounting wall or ceiling. It is recommended that the MR32 be mounted to a wall or solid ceiling using the mount cradle for physical security reasons.

Drop ceiling mount using mount cradle

To mount your MR32 on a drop ceiling T-rail, use the included drop ceiling mounting accessory kit. The accessory kit can be used to mount to most 9/16”, 15/16” or 1 ½” T-rails. The kit contains:

  • Drop ceiling mounting clips with set screws

 

  • 6-32x4 mm screws

 

  • 6-32x7 mm screws only used for recessed rail mount (uncommon)

 

  • 2 rubber spacers

 

  1. Attach the T-rail clips to the T-rail by rotating them and snapping them into place as shown. The black foam pads should be compressed slightly after installation.

     
  2. Using the dashed lines on the mount cradle template as a guide, set the proper spacing of the T-rail clips on the T-rail.
  3. Tighten the set screws on the T-rail clips to secure the clips using a 5/64”(2 mm) hex key.

     
  4. Attach the mount cradle to the T-rail clips using the mount cradle holes (marked with a “T“).

Tip: Pre-assemble rubber spacers and screws to the mount cradle. The mount cradle can then be held with one hand while the other hand holds a screwdriver. If mounting your MR32 to a dropped ceiling, skip to the "Power the MR32" section. 

Electrical Junction Box Mount Using mount cradle

The MR32 can be mounted to a 4” square cable junction box, a 3.5 or 4” round cable junction box, or various U.S. and European outlet boxes (mounting screws are not included). 
Using appropriate mounting hardware for your specific type of junction box, attach the mount cradle to the junction box.

Plenum Mount (Above Drop Ceiling)

The MR32 can be mounted to the T-bar grid above the tiles of a drop ceiling using a 3rd party T-bar box hanger (not included). The Erico Caddy 512A is recommended and is used in installation instruction illustrations. Note: a UL2043-rated Ethernet cable should be used for a plenum installation.

  1. Adjust the height of the T-bar box hanger crossbar to make sure there is adequate clearance between the access point and the top of the ceiling tiles. Tighten the height adjusting screws.
  2. Attach the bracket mounting clip (included with T-bar box hanger) to the center of the T-bar box hanger crossbar.
  3. Attach the MR32 mount cradle to the access point mounting bracket using a 6-32 screw, washer, and nut (not included with T-bar box hanger) and the Above Drop Ceiling (Box Hanger) hole in the mount cradle (reference Mounting Template).
  4. Securely attach the clips on either side of the T-bar box hanger to the suspended ceiling grid T-rails.
  5. Connect a grounding wire (not included with T-bar box hanger) to the grounding hole in the bracket mounting clip and to metal building structure. A grounding wire is required to comply with the U.S. National Electric Safety Code.

Power the MR32

If mounting to an electrical junction box, feed the Ethernet cable through the cable access hole in the mount cradle. If mounting to a wall or ceiling, the Ethernet cable will feed from behind the MR32.

Powering the MR32 with the Meraki AC Adapter (sold separately)

1. Plug the power cord into the MR32 and the other end into a wall outlet.
2. Plug an Ethernet cable that is connected to an active Ethernet connection into the Eth0 port on the MR32.

Powering the MR32 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 Eth0 port in the cable bay of the MR32.

Powering the MR32 with an 802.3af Power over Ethernet Switch

Route Ethernet cable from a port on an active 802.3af PoE switch to the Eth0 port in the bay of the MR32. The MR32 is Gigabit Ethernet-capable. To maximize device performance, a Gigabit-capable switch should be used.

Meraki switches are 802.3at compatible and will power the MR32 by default, using LLDP negotiating. When using Cisco switches, an extra step may be required to configure the Cisco switch to use LLDP to communicate with the Meraki MR32; see the following article for more details: https://documentation.meraki.com/MR/Other_Topics/Low_Power_Mode_on_Cisco_Switches​

Mount the MR32

Attach the MR32 to the Mount Cradle

(This section applies to wall and/or solid ceiling, drop ceiling or electrical junction box mount 
where you have already installed the mount cradle.)

The MR32 attaches to the mount cradle with two tabs on the cradle that insert into the MR32, and is secured to the cradle using one screw.

To attach the MR32 to the mount cradle properly, line up the top edge of the AP with the top tab of the mount cradle. Since the cradle is already mounted to the wall, guide the MR32 towards the top tab and insert the top tab into the MR32’s slot.

 

Then adjust the MR32 to guide the MR32’s bottom slot into the cradle’s bottom tab until it clicks into place. Once in place, the MR32 should be secured to the cradle by using one of the included screws in the cradle’s bottom tab.

 

To release the MR32 from the mount cradle, first remove the security screw that secures the MR32 to the cradle’s bottom tab. While holding the MR32 with one hand, press the cradle’s bottom tab upwards, releasing the MR32 from the bottom of the cradle. Then remove the MR32 from the cradle’s top tab.

Desk or Shelf Mount

The MR32 can be placed on a desk or shelf resting on the non-scratch rubber feet. The mount cradle is not necessary for a desk or shelf installation.

Secure the MR32

Depending on your mounting environment, you may want to secure the MR32 to its mount location. Your MR32 can be secured in several ways. If the MR32 has been installed using the mount cradle, it should be secured via security screw (Torx security screws are included) and/or Kensington lock. If the mount cradle was not used, the MR32 can still be secured using a Kensington lock.

Security Screw

Install the security screw in the lower mount cradle tab.

Kensington Lock

Attach a Kensington lock cable to the access point at the hard point on the side of the device.
Attach the other end of the cable to a secure location, such as a pipe or building fixture.

Verify Device Functionality and Test Network Coverage

  1. Check LEDs
    1. The Power LED should be solid green (or blue, if clients are connected). If it is flashing blue, the firmware is automatically upgrading and the LED should turn green when the upgrade is completed (normally within a few minutes). See the "LED Indicators" section for more details. .
    2. Note: Your MR32 must have an active route to the Internet to check and upgrade its firmware.
  2. Verify access point connectivity
    1. Use any 802.11 client device to connect to the MR32 and verify proper connectivity using the client’s web browser.
  3. Check network coverage
  4. 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.
