Factory Reset ButtonIf the button is pressed and held for at least five seconds and then released, the MR42E will reboot and be restored to its original factory settings by deleting all configuration information stored on the unit.LED Indicators and Run Dark ModeYour MR42E 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 uplinkThe MR42E 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 PreparationYou should complete the following steps before going on-site to perform an installation.Configure Your Network in DashboardThe following is a brief overview only of the steps required to add an MR42E 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 serialnumber of each AP, which looks like Qxxx-xxxx-xxxx, and is found on the bottom of the unit. You will also needyour 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 youplan to mount it.Check and Upgrade FirmwareTo ensure your MR42E performs optimally immediately following installation, it is recommended that you facilitate a firmware upgrade prior to mounting your MR42E.1. Attach your MR42E to power and a wired Internet connection. See the "Power the MR42E" section for details.6
2. The MR42E will turn on and the LED will glow solid orange. If the unit does not require a firmware upgrade, the LEDwill 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 LEDwill turn solid green or blue. You should allow at least a few minutes for the firmware upgrade to complete, depending onthe speed of your internet connection.Check and Configure Firewall SettingsIf a firewall is in place, it must allow outgoing connections on particular ports to particular IP addresses. The mostcurrent list of outbound ports and IP addresses for your particular organization can be found here.Assigning IP Addresses to MR42sAll gateway MR42s (MR42s with Ethernet connections to the LAN) must be assigned routable IP addresses. These IPaddresses can be dynamically assigned via DHCP or statically assigned.Dynamic AssignmentWhen using DHCP, the DHCP server should be configured to assign a static IP address for each MAC addressbelonging to a Meraki AP. Other features of the wireless network, such as 802.1X authentication, may rely on theproperty that the APs have static IP addresses.Static AssignmentStatic IPs are assigned using the local web server on each AP. The following procedure describes how to set thestatic 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 MR42E either through a PoE switch or a PoE Injector. If using a PoE switch, plug an Ethernet cable into the MR42E’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 MR42E 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 browsingto 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 ReservationsInstead of associating to each Meraki AP individually to configure static IP addresses, an administrator canassign static IP addresses on the upstream DHCP server. Through “DHCP reservations,” IP addresses are7
“reserved” for the MAC addresses of the Meraki APs. Please consult the documentation for the DHCP server toconfigure DHCP reservations.Collect ToolsYou will need the following tools to perform an installation:Collect Additional Hardware for InstallationYou will need the following hardware to perform an installation:8
Installation InstructionsChoose Your Mounting LocationA good mounting location is important to getting the best performance out of your MR42E 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 MR42E 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 MR42EFor most mounting scenarios, the MR42E 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 MR42E to the mount cradle.Attach the mount cradleThe MR42E 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 cradletemplate shows the hole patterns that should be used for each type of mount.Wall or Solid Ceiling Mount Using mount cradleUsing included wall anchors and screws, attach the mount cradle to your mounting wall or ceiling. It is recommended that the MR42E be mounted to a wall or solid ceiling using the mount cradle for physical security reasons.Drop ceiling mount using mount cradleTo mount your MR42E 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 screws9
• 6-32x4 mm screws• 6-32x7 mm screws only used for recessed rail mount (uncommon)• 2 rubber spacers1. Attach the T-rail clips to the T-rail by rotating them and snapping them into place as shown. The black foampads should be compressed slightly after installation.10
2. Using the dashed lines on the mount cradle template as a guide, set the proper spacing of the T-rail clips onthe T-rail.3. Tighten the set screws on the T-rail clips to secure the clips using a 5/64”(2 mm) hex key.11
4. 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 MR42E to a dropped ceiling, skip to the "Power the MR42E" section.Electrical Junction Box Mount Using mount cradleThe MR42E 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 MR42EIf 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 MR42E. The "Power Source Options" section of this document lists the different powering options and their unique characteristics.Mount the MR42E12

Verify Device Functionality and Test Network Coverage1. Check LEDsa. 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. .b. Note: Your MR42E must have an active route to the Internet to check and upgrade its firmware.2. Verify access point connectivitya. Use any 802.11 client device to connect to the MR42E and verify proper connectivity using the client’s web browser.3. Check network coverage4. 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.
