Check and Upgrade Firmware

To ensure your MR18 performs optimally immediately following installation, it is recommended that you facilitate a

ﬁrmware upgrade prior to mounting your MR18.

1. Attach your MR18 to power and a wired Internet connection. See the

2. The MR18 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 MR18s

All gateway MR18s (MR18s 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 MR18 either through a PoE switch or a PoE Injector.

If using a PoE switch, plug an Ethernet cable into the MR18'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 MR18

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.
