Understanding the MR20-HW

Your Meraki MR20-HW has the following features:

The mount plate has the following features:

Security Features

The MR20-HW features multiple options for physically securing the access point after

installation:

1. Security screw – The accessory kit includes screws that can be used to secure the

access point to the mount cradle. Engaging the security screw prevents accidental

dislodging and theft.

Ethernet Ports

The MR20-HW features a Gigabit Ethernet RJ45 port that accepts 802.3at and 802.3af

power (labeled “Eth0, PoE”). This port should be used for uplink to your WAN connection.

Power Source Options

The MR20-HW access point can be powered using either the Meraki AC Adapter, PoE

Injector (both sold separately), or a third-party PoE switch.

Factory Reset Button

If the button is pressed and held for at least ﬁve seconds and then released, the MR20-

HW will reboot and be restored to its original factory settings by deleting all conﬁguration

information stored on the unit.

LED Indicators and Run Dark Mode

Your MR20-HW is equipped with a multi-color LED light on the front 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 MR20-HW 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.

Conﬁgure Your Network in Dashboard

The following is a brief overview only of the steps required to add an MR20-HW 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. 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 MR20-HW performs optimally immediately following installation, it is

recommended that you facilitate a ﬁrmware upgrade prior to mounting your MR20-HW.

1. Attach your MR20-HW to power and a wired Internet connection. See the "Power

the MR20-HW" section for details.

2. The MR20-HW 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 MR20-HWs

All gateway MR20-HWs (MR20-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.

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 MR20-HW either

through a PoE switch or a PoE Injector. If using a PoE switch, plug an Ethernet

cable into the MR20-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

PoE Injector, connect the MR20-HW 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.

Installation Instructions

Choose Your Mounting Location

A good mounting location is important to getting the best performance out of your

MR20-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 MR20-HW should have line of sight to at

least two other Meraki devices. A Cisco Partner can help ensure that your AP

placement is ideal.

Mount the MR20-HW

Attach the MR20-HW to the Mount Cradle

The MR20-HW attaches to the mount cradle with two tabs on the cradle that insert into

the MR20-HW, and is secured to the cradle using one screw.

To attach the MR20-HW to the mount cradle properly, line up the top edge of the AP with

the top tab of the mount cradle. Since the cradle is already mounted to the wall, guide

the MR20-HW towards the top tab and insert the top tab into the MR20-HW’s slot.

Then adjust the MR20-HW to guide the MR20-HW’s bottom slot into the cradle’s bottom

tab until it clicks into place. Once in place, the MR20-HW should be secured to the cradle

by using one of the included screws in the cradle’s bottom tab.

Power the MR20-HW

If mounting to an electrical junction box, feed the Ethernet cable through the cable

access hole in the mount cradle. If mounting to a wall or ceiling, the Ethernet cable will

feed from behind the MR20-HW. The "Power Source Options" section of this document

lists the different powering options and their unique characteristics.

Mount the MR20-HW

Attach the MR20-HW to the Mount Cradle

(This section applies to wall and/or solid ceiling, drop ceiling or electrical junction box

mount

where you have already installed the mount cradle.)

The MR20-HW attaches to the mount cradle with two tabs on the cradle that insert into

the MR20-HW, and is secured to the cradle using one screw.

To attach the MR20-HW to the mount cradle properly, line up the top edge of the AP with

the top tab of the mount cradle. Since the cradle is already mounted to the wall, guide

the MR20-HW towards the top tab and insert the top tab into the MR20-HW’s slot.

Then adjust the MR20-HW to guide the MR20-HW’s bottom slot into the cradle’s bottom

tab until it clicks into place. Once in place, the MR20-HW should be secured to the cradle

by using one of the included screws in the cradle’s bottom tab.

Error!%Reference%source%not%found.

To release the MR20-HW from the mount cradle, first remove the security screw that

secures the MR20-HW to the cradle’s bottom tab. While holding the MR20-HW with one

hand, press the cradle’s bottom tab upwards, releasing the MR20-HW from the bottom of

the cradle. Then remove the MR20-HW from the cradle’s top tab.

Desk or Shelf Mount

The MR20-HW can be placed on a desk or shelf resting on the non-scratch rubber feet.

The mount cradle is not necessary for a desk or shelf installation.

Secure the MR20-HW

Depending on your mounting environment, you may want to secure the MR20-HW to its

mount location. Your MR20-HW can be secured in several ways. If the MR20-HW has

been installed using the mount cradle, it should be secured via security screw (Torx

security screws are included) and/or Kensington lock. If the mount cradle was not used,

the MR20-HW can still be secured using a Kensington lock.

Power the MR20-HW

If mounting to an electrical junction box, feed the Ethernet cable through the cable

access hole in the mount cradle. If mounting to a wall or ceiling, the Ethernet cable will

feed from behind the MR20-HW. The "Power Source Options" section of this document

lists the different powering options and their unique characteristics.

Verify Device Functionality and Test Network Coverage

1. Check LEDs

a. The Power LED should be solid green (or blue, if clients are connected). If it

is ﬂashing blue, the ﬁrmware is automatically upgrading and the LED

should turn green when the upgrade is completed (normally within a few

minutes). See the "LED Indicators" section for more details. .
