1 Scope of Document and Related Publications The MR42 Hardware Installation Guide describes the installation procedure for the MR42 indoor access point. Additional reference documents are available online at www.meraki.com/library/product.
2 MR42 Overview The Meraki MR42 is an enterprise-class, dual-concurrent 3x3 MIMO 802.11ac indoor access point designed for high-density deployments in offices, schools, hospitals and hotels. When connected to the Meraki Cloud Control ler, the MR42 enables the creation of ultra-high speed, reliable indoor wireless networks quickly, easily and cost- effectively. 2.

2.3 Security Features The MR42 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 plate. Engaging the security screw prevents accidental dislodging and theft. 2. 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. 2.
3 Pre-Install Preparation You should complete the following steps before going on-site to perform an installation. 3.1 Configure Your Network in Dashboard The following is a brief overview only of the steps required to add an MR42 to your network. For detailed instructions about creating, configuring and managing Meraki wireless networks, refer to the Meraki Cloud Controller Manual (meraki.com/library/product). 1. Login to http://dashboard.meraki.com. If this is your first time, create a new account. 2.
3.4 Assigning IP Addresses to MR42s All gateway MR42s (MR42s with Ethernet connections to the LAN) must be assigned routable IP addresses. These IP addresses can be dynamically assigned via DHCP or statically assigned. 3.4.1 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.
3.5 Collect Tools You will need the following tools to perform an installation: Phillips screwdriver Hammer Drill with 1/4” (6.3mm) bits 3.6 Collect Additional Hardware for Installation or 802.3at PoE power source (either PoE switch or Meraki 802.
4 Installation Instructions 4.1 Choose Your Mounting Location A good mounting location is important to getting the best performance out of your MR42 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.
4.2.1.1 Wall or Solid Ceiling Mount Using Mount Plate Using included screws, attach the mount plate to your mounting wall or ceiling. It is recommended that the MR42 be mounted to a wall or solid ceiling using the mount plate for physical security reasons. If mounting your MR42 to a wall, skip to “Power the MR42“ on P.
4.2.1.2 Drop Ceiling Mount Using Mount Plate To mount your MR42 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: Dropped ceiling mounting clips with set screws 6-32x4 mm screws 6-32x7 mm screws Only used for recessed rail mount (uncommon) 2 rubber spacers Only used for recessed rail mount (uncommon) 1.
2. Using the dashed lines on the mount plate template as a guide, set the proper spacing of the T-rail clips on the T-rail 3. Tighten the set screws on the T-rail clips to secure the clips using a 5/64”(2 mm) hex key.
4. Attach the mount plate to the T-rail clips using the mount plate holes (marked with a “T“). To select the correct set of mounting hardware to use, first determine whether you are mounting to a “flush” or “recessed“ rail.
4.2.1.3 Electrical Junction Box Mount Using Mount Plate The MR42 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 plate to the junction box.
4.2.2 Power the MR42 If mounting to an electrical junction box, feed the Ethernet cable through the cable access hole in the Mount Plate: If mounting to a wall or ceiling, the Ethernet cable will feed through the cable slot on bottom of the MR42.
4.2.2.1 Powering the MR42 with the Meraki AC Adapter (sold separately) 1. Plug the power cord into the MR42 and the other end into a wall outlet. 2. Plug an Ethernet cable that is connected to an active Ethernet connection into the Eth0 port on the MR42. 4.2.2.2 Powering the M42 with the Meraki 802.3at Power over Ethernet Injector (sold separately) 1. Plug the power cord into the PoE Injector and the other end into wall power. 2.
4.2.2.3 Powering the MR42 with an 802.3at Power over Ethernet Switch Route Ethernet cable from a port on an active 802.3at PoE switch to the Eth0 port in the bay of the MR42. The MR42 is Gigabit Ethernet-capable. To maximize device performance, a Gigabit-capable switch should be used. 4.2.
4.2.3.2 Assemble MR42 to the Mount Plate (This section applies to wall and/or solid ceiling, drop ceiling or electrical junction box mount where you have already installed the mount plate.) Insert the top latch on the mount plate into the top mount plate attachment slots on the back of the device. Rotate the bottom of the unit into the bottom ount plate attachment slot. The unit will click into place.
4.2.3.3 Desk or Shelf Mount The MR42 can be placed on a desk or shelf resting on the non-scratch rubber feet. The mount plate is not necessary for a desk or shelf mounting.
4.3 Secure the MR42 Depending on your mounting environment, you may want to secure the MR42 to its mount location. Your MR42 can be secured in several ways. If the MR42 has been installed using the mount plate, it can be secured via security screw (Torx and phillips head security screws are included; choose one), and/or Kensington lock. If the mount plate was not used, the MR42 can still be secured using a Kensington lock. 4.3.
4.4 Verify Device Functionality and Test Network Coverage 1. Check LEDs The LED should be solid white. If it is flashing orange, the firmware is automatically upgrading and the LED should turn green when the upgrade is completed (normally in under thirty minutes). Note: Your MR42 must have an active route to the Internet to check and upgrade its firmware. 2. Verify access point connectivity Use any 802.
If the device is going to be operated in the 5.15 - 5.25 frequency range, then it is restricted to indoor environment only. This device meets all other requirements specified in Part 15E, Section 15.407 of the FCC Rules. Industry Canada Statement This device complies with RSS-210 of the Industry Canada Rules.
