MA-UMNT-MR-A3 Aruba Mounting Adapter Installation Guide



The MA-UMNT-MR-A3 is a universal mounting adapter designed to simplify the transition from Aruba to Cisco Meraki access points. This adapter works with MR33, MR42/42E, MR52, MR53/53E, MR45/55, MR36/46/46E/56 indoor access points. MA-UMNT-MR-A3 can be attached directly to the Aruba mount without the need to remove this mount from its current mounting location. Supported Aruba mounts: JW046A, JW047A, AP-200-MNT-W2, AP-220-MNT-W2, AP-220-MNT-W2W.

Installation Instructions

Remove the current Aruba access point from the Aruba mount and ensure that the security lock on MA-UMNT-MR-A3 is not engaged.




  1. If JW046A / JW047A Aruba mounts are used, position the MA-UMNT-MR-A3 to align with the currently installed Aruba mount, placing the MA-UMNT-MR-A3 so that it’s mounting tabs are at an angle of approximately 30 degrees to the Aruba mount. Pushing toward the wall, rotate the MA-UMNT-MR-A3 clockwise until it clicks into place. 


If AP-200-MNT-W2 / AP-220-MNT-W2 / AP-220-MNT-W2W Aruba mounts are used, align the pins on the rear panel of the MA-UMNT-MR-A3 with the slots on the Aruba mount plate. Press the button on the bottom on the Aruba mount in and slide the MA-UMNT-MR-A3 into the Aruba mount until the pins are fully engaged. Release the button to secure the MA-UMNT-MR-A3 to the Aruba mount. For additional security, insert the Torx security screw into the hole located next to the button to lock the MA-UMNT-MR-A3 to the Aruba mount.



  1. Use a Phillips head screwdriver to secure MA-UMNT-MR-A3 and ensure it’s in a locked position.



  1. Use the two Phillips head screws included in the mount kit to attach your Meraki mount cradle to the MA-UMNT-MR-A3 mount.



Attach your Meraki access point to the Meraki mount cradle by lining up the top edge of the AP with the top tab of the mount cradle. Since the cradle is already mounted to MA-UMNT-MR-A3 universal mount, guide the AP towards the top tab and insert the top tab into the AP slot.


Then adjust your AP to guide the bottom slot into the cradle’s bottom tab until it clicks into place. 


Once in place, the AP should be secured to the cradle by using one of the included screws in the cradle’s bottom tab.




  1. Run Ethernet cable(s) to LAN Access ports of your Meraki access point and connect into the appropriate LAN Access port(s). Note some Meraki APs have 1x LAN port and some have 2x LAN ports. Secure the AP with a Torx security screw.
