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 MR76-HW 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 shippin[email protected].
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.
3.2 Check and Upgrade Firmware
To ensure your MR76-HW performs optimally immediately following installation, Meraki recommends
that you facilitate a firmware upgrade prior to mounting your MR76-HW.
1. Attach your MR76-HW to power and a wired Internet connection. See p. 19 of this
Hardware Installation Guide for details.
2. The MR76-HW 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 white 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 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 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:

9
3.4 Assigning IP Addresses to MR76-HWs
All gateway MR76-HWs (MR76-HWs 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 MR76-HW either through a PoE switch
or a Meraki PoE Injector. If using a PoE switch, plug an Ethernet cable into the MR76-HW’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 MR76-HW 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
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.

4 Installation Instructions
4.1 Choose Your Mounting Location
A good mounting location is important to getting the best performance out of your MR76-HW
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 MR76-HW 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).
4.2 Install the MR76-HW
For most mounting scenarios, the MR76-HW 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 MR76-HW to the mount plate.
!!! This equipment is only suitable for mounting at heights ≤ 2 m !!!
4.2.1
Attach the Mount Plate
The MR76-HW 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:
