MR74 Overview

The Meraki MR74 is an enterprise-class, 802.11abgn/ac AP outdoor designed for rugged environments. When connected to the Meraki Cloud Controller, the MR74 enables the creation of high-speed and reliable networks that cover large outdoor and industrial areas quickly, easily, and cost-effectively.

The Meraki MR74 has an operating temperature of -40o to 60o C.

2.1

Package Contents

The MR74 package contains the following:

- MR74 access point

- Wall screws & anchors

- Mounting plate

- Cable gland

- Mounting straps

2.2

Antennas and Ports

The Meraki MR74 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 MR74: MAANT-20, MA-ANT-21, MA-ANT-23, MA-ANT-25, MA-ANT-27, and Cisco AIR-ANT2513P4M-N.

The Meraki MA-ANT-20 omni-directional antennas must be installed vertically.

The Meraki MA-ANT-21, MA-ANT-23, MA-ANT-25, MA-ANT-27, and Cisco AIR-ANT2513P4M-N antennas must be installed facing downward, at least 30 degrees from the horizon line.

2.3

Power Source Options

The MR74 access point can be powered using either an 802.3af capable PoE switch or the Meraki 802.3af PoE injector (sold separately).

2.4

LED Indicators and Run Dark Mode

Your MR74 uses a single LED to inform the user of the device’s status.

The MR74 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 Meraki Dashboard.

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 MR74 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 MR74 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 MR74 performs optimally immediately following installation, Meraki recommends that you facilitate a firmware upgrade prior to mounting your MR74.

1. Attach your MR74 to power and a wired Internet connection.

2. The MR74 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 MR74 to be able to seamlessly communicate with the Cloud Controller. The most current list of outbound ports and IP addresses can be found here:

3.4

Assigning IP Addresses to MR74s

All gateway MR74s (MR74s 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 MR74 either through a PoE switch or a Meraki PoE Injector. If

using a PoE switch, plug an Ethernet cable into the MR74’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 MR74 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 the AP’s serial number, with hyphens included (e.g., Q2BD-551CZYW3), and the default password is blank.

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

- 802.3af PoE power source (either PoE switch or Meraki 802.3af PoE

Injector)
