These are the 4 outdoor AP mounting brackets for Aruba AP 270 series, 360 series, 370 series 275, 365, 367, 374, 377, 374, 380
MNT-H1 - JW054A - Hanging install (can tilt)
MNT- H2 - JW055A - Hanging install (flush, cannot tilt)
MNT-V1 - JW052A - Long arm pole/wall mount (300mm from wall)
MNT-V2 - JW053A - Short arm pole/wall mount (75mm from wall)
Important: If using AP377 or AP387 or other directional AP, don't use the wall mount or you'll end up aiming the antennas at the floor! Rather use the MNT-H1 mount on a wall or pole.
