Understanding the MR33
Your Meraki MR33 has the following features:
The mount cradle has the following features:
The MR33 features multiple options for physically securing the access point after installation:
- 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.
- Kensington lock – The access point contains a hard point that allows it to be secured to any nearby permanent structure using a standard Kensington lock.
The MR33 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 MR33 access point can be powered using either the Meraki AC Adapter, PoE Injector (both sold separately), or a PoE switch.
Factory Reset Button
If the button is pressed and held for at least ﬁve seconds and then released, the MR33 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 MR33 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 MR33 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.
NOTE: Blinking Green LED indicates that the device is in site survey mode. Please see the Conducting Site Surveys with MR Access Points for more details.
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 MR33 to your network. For detailed instructions about creating, conﬁguring and managing Meraki wireless networks, refer to the online documentation (documentation.meraki.com).
- Login to http://dashboard.meraki.com. If this is your ﬁrst time, create a new account.
- Find the network to which you plan to add your APs or create a new network.
- 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.
- 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 MR33 performs optimally immediately following installation, it is recommended that you facilitate a ﬁrmware upgrade prior to mounting your MR33.
- Attach your MR33 to power and a wired Internet connection. See the "Power the MR33" section for details.
- The MR33 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 MR33s
All gateway MR33s (MR33s with Ethernet connections to the LAN) must be assigned routable IP addresses. These IP addresses can be dynamically assigned via DHCP or statically assigned.
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 IPs are assigned using the local web server on each AP. The following procedure describes how to set the static IP:
- Using a client machine (e.g., a laptop), connect to the AP wirelessly (by associating to any SSID broadcast by the AP).
- 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 IP address, net mask, gateway IP address and DNS servers that this AP will use on its wired connection.
- 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.

You will need the following hardware to perform an installation:
Choose Your Mounting Location
A good mounting location is important to getting the best performance out of your MR33 access point. Keep the following in mind:
- 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.
- Power over Ethernet supports a maximum cable length of 300 ft (100 m).
- If being used in a mesh deployment, the MR33 should have line of sight to at least two other Meraki devices. A Cisco Partner can help ensure that your AP placement is ideal.
Install the MR33
For most mounting scenarios, the MR33 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 MR33 to the mount cradle.
Attach the mount cradle
The MR33 mount cradle 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.
The mount cradle contains a variety of hole patterns that are customized for each installation scenario. The mounting template (included inbox with mount cradle) should be used to drill holes for wall mounts and also to identify the correct hole patterns in the mount cradle that should be used for each type of mount. The included mount cradle template shows the hole patterns that should be used for each type of mount.
Wall or Solid Ceiling Mount Using mount cradle
Using included wall anchors and screws, attach the mount cradle to your mounting wall or ceiling. It is recommended that the MR33 be mounted to a wall or solid ceiling using the mount cradle for physical security reasons.
Drop ceiling mount using mount cradle
To mount your MR33 on a drop ceiling T-rail, use the included drop ceiling mounting accessory kit. The accessory kit can be used to mount to most 9/16”, 15/16” or 1 ½” T-rails. The kit contains:
- Drop ceiling mounting clips with set screws
- 6-32x4 mm screws
- 6-32x7 mm screws only used for recessed rail mount (uncommon)
- 2 rubber spacers
- Attach the T-rail clips to the T-rail by rotating them and snapping them into place as shown. The black foam pads should be compressed slightly after installation.
- Using the dashed lines on the mount cradle template as a guide, set the proper spacing of the T-rail clips on the T-rail.
- Tighten the set screws on the T-rail clips to secure the clips using a 5/64”(2 mm) hex key.
- Attach the mount cradle to the T-rail clips using the mount cradle holes (marked with a “T“).
Tip: Pre-assemble rubber spacers and screws to the mount cradle. The mount cradle can then be held with one hand while the other hand holds a screwdriver. If mounting your MR33 to a dropped ceiling, skip to the "Power the MR33" section.
Electrical Junction Box Mount Using mount cradle
The MR33 can be mounted to a 4” square cable junction box, a 3.5 or 4” round cable junction box, or various U.S. and European outlet boxes (mounting screws are not included).
Using appropriate mounting hardware for your specific type of junction box, attach the mount cradle to the junction box.
Power the MR33
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 MR33. The "Power Source Options" section of this document lists the different powering options and their unique characteristics.
Mount the MR33
Attach the MR33 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 MR33 attaches to the mount cradle with two tabs on the cradle that insert into the MR33, and is secured to the cradle using one screw.
To attach the MR33 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 MR33 towards the top tab and insert the top tab into the MR33’s slot.
Then adjust the MR33 to guide the MR33’s bottom slot into the cradle’s bottom tab until it clicks into place. Once in place, the MR33 should be secured to the cradle by using one of the included screws in the cradle’s bottom tab.
To release the MR33 from the mount cradle, first remove the security screw that secures the MR33 to the cradle’s bottom tab. While holding the MR33 with one hand, press the cradle’s bottom tab upwards, releasing the MR33 from the bottom of the cradle. Then remove the MR33 from the cradle’s top tab.
Desk or Shelf Mount
The MR33 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 MR33
Depending on your mounting environment, you may want to secure the MR33 to its mount location. Your MR33 can be secured in several ways. If the MR33 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 MR33 can still be secured using a Kensington lock.
Install the security screw in the lower mount cradle tab.
Attach a Kensington lock cable to the access point at the hard point on the side of the device.
Attach the other end of the cable to a secure location, such as a pipe or building ﬁxture.
Verify Device Functionality and Test Network Coverage
- Check LEDs
- 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. .
- Note: Your MR33 must have an active route to the Internet to check and upgrade its ﬁrmware.
- Verify access point connectivity
- Use any 802.11 client device to connect to the MR33 and verify proper connectivity using the client’s web browser.
- Check network coverage
- Conﬁrm that you have good signal strength throughout your coverage area. You can use the signal strength meter on a laptop, smart phone, or other wireless device.
