Pre-install Preparation
You should complete the following steps before going on-site to perform an installation.
Configure your Dashboard Network
The following is a brief overview only of the steps required to add an access point to your network. For detailed
instructions about creating, configuring and managing Meraki wireless networks, refer to the online documentation
(documentation.meraki.com).
1. Login to http://dashboard.meraki.com. f 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 Set Firmware
To ensure your access point performs optimally immediately following installation, it is recommended that you facilitate a
firmware upgrade prior to mounting your AP.
1. Attach your AP to power and a wired nternet connection. See the "Power the Ap" section for details.
2. The AP will turn on and the LED will glow solid orange. f the unit does not require a firmware upgrade, the LED
will turn either green (no clients associated) or blue (clients associated) within thirty seconds.
* f 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 Upstream Firewall Settings
f a firewall is in place, it must allow outgoing connections on particular ports to particular P addresses. The most
current list of outbound ports and P addresses for your particular organization can be found on the firewall configuration
page in your dashboard.
Assigning an P Address
All gateway A (An AP with Ethernet connections to the LAN) must be assigned routable P addresses. These P
addresses can be dynamically assigned via DHCP or statically assigned.
8
Dynamic Assignment
• When using DHCP, the DHCP server should be configured to assign a static P 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 P addresses.
Static Assignment
• Static Ps are assigned using the local web server on each AP. The following procedure describes how to set the
static P:
• Using a client machine (e.g., a laptop), connect to the AP wirelessly (by associating to any SS D broadcast by the
AP) or over a wired connection.
• f using a wired connection, connect the client machine to the AP either through a PoE switch or a PoE njector. f
using a PoE switch, plug an Ethernet cable into the AP’s Ethernet jack, and the other end into a PoE switch. Then
connect the client machine over Ethernet cable to the PoE switch. f using a PoE njector, connect the AP to the
“PoE” port of the njector, and the client machine to the “LAN” port.
• 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.
• 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).
• Configure the static P address, net mask, gateway P address and DNS servers that this AP will use on its wired
connection.
• f necessary, reconnect the AP to the LAN.
Static IP via DHCP Reservations
• nstead of associating to each Meraki AP individually to configure static P addresses, an administrator can assign
static P addresses on the upstream DHCP server. Through “DHCP reservations,” P 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:
T8 Torx Screwdriver, Phillips screwdriver, Hammer, Drill with 1/4" (6.3mm) bits

Collect Additional Hardware for nstallation
You will need the following hardware to perform an installation:
802.3at PoE Power Source (either PoE switch or Meraki 802.3at PoE Injector) or an AC adaptor and network cables
with RJ45 connectors long enough for your particular mounting location
nstallation nstructions
Warning: Due to the heat dissipation in the back of APs during normal operation, please do not stack powered on APs
on top of each other during pre-installation to avoid heat damage.
Choose Your Mounting Location
A good mounting location is important to getting the best performance out of your 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. f being used in a mesh deployment, the AP should have line of sight to at least two other Meraki devices. A Cisco
Partner can help ensure that your AP placement is ideal.
nstall the AP
For most mounting scenarios, the access point 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 AP to the mount cradle.
Attach the Mount Cradle
The access point mount cradle can be used to install your access point in a wide range of scenarios: wall or solid ceiling,
