Understanding the MR84

LED indicator

Your MR84 is equipped with a multi-color LED light on the bottom edge 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 MR84 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.

Ethernet Port

The MR84 features 2 Ethernet ports:

The labeled “PoE” accepts 802.3at and 802.3af power and should be used as the primary uplink to your LAN/WAN.

The 2nd port may be used for LACP bonding with the PoE port

Link Aggregation

The second Ethernet port can be used in a bonded configuration with the "PoE" port. Ensure that the AP is plugged into 2 switch ports on the same Ethernet switch that have been configured for LACP bonding. Keep in mind that the maximum bonded aggregate bandwidth is 2.0 Gbps. See the MR Link Aggregation Configuration

N-Type antenna attachment ports (4x)

2x N-Type antenna ports are located at the top of the MR84 and 2x are located at the bottom of the MR84. The 4 antenna ports are connected to both 2.4 GHz and 5 GHz client serving radios. In order to ensure highest performance, ensure antennas connected to the 4 ports have overlapping coverage areas.

Mount plate attachment slots (4x)

The mounting slots located on the rear shell of the MR84 marry to the 4 mounting posts on the mounting plate, securely fastening the MR84 to the mounting plate.

Factory reset button

The factory reset button is located in a small pin-sized hole just above the PoE Ethernet port of the MR84. If the button is pressed and held for at least ﬁve seconds and then released, the MR84 will reboot and be restored to its original factory settings by deleting all configuration information stored on the unit.

The Vent

The vent allows pressure equalization between the interior and the environment. This prevents internal condensation and maintains a waterproof seal.

Understanding the MR84 mount plate

The mount plate is unique to the MR84. Previous outdoor AP mount plates are not compatible with the MR84.

The mount cradle has the following features:

Mounting posts (4x)

The mounting slots located in the middle of the mounting plate marry the MR84 to the mounting plate.

Mounting holes (4x)

The mounting holes located on the 4 outermost corners of the mounting plate allow secure installation of the mounting plate to a surface such as a wall.

Vertical orientation mounting strap slots (2x)

The vertical orientation mounting strap slots located in the middle of the mounting plate secure the mounting plate to a vertical pole using the included mounting straps.

Horizontal orientation mounting strap slots (2x)

The horizontal orientation mounting strap slots located in the middle of the mounting plate secure the mounting plate to a horizontal pole using the included mounting straps.

Release tab

The release tab located at the bottom of the mounting plate. It locks the movement of the AP once attached.

Mount plate attachment screw

The mount plate attachment screw is located at the bottom of the mounting plate. It securely attaches the AP to the mounting plate.

Mount plate grounding post

The mount plate grounding post located on the left side of the mounting plate. Using the included grounding strap, the ground post allows you to ground the unit.

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 MR84 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 MR84 performs optimally immediately following installation, it is recommended that you facilitate a ﬁrmware upgrade prior to mounting your MR84.

1. Attach your MR84 to PoE enabled wired Internet connection. See the "Power the MR84" section for details.

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 either green (no clients associated) or blue (clients associated) within thirty seconds.

* If the unit requires an upgrade, the LED will begin blinking blue 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 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.

Dynamic Assignment (Recommended)

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 MR84 either through a PoE switch or a 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 PoE Injector, connect the MR84 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.

Collect Tools

You will need the following tools to perform an installation:

Collect Additional Hardware for Installation

You will need the following tools to perform an installation:
