Aruba AP-120 Series Indoor Access Point
| Installation Guide
Using the Integrated Ceiling Tile Rail Slots
The snap-in tile rail slots on the rear of the AP can be used to securely attach the device directly to a 15/
16” wide, standard ceiling tile rail.
1. Pull the necessary cables through a prepared hole in the ceiling tile near where the AP will be
placed.
2. If necessary, connect the console cable to the console port on the back of the AP.
3. Hold the AP next to the ceiling tile rail with the ceiling tile rail mounting slots at approximately a 30-
degree angle to the ceiling tile rail (see
Figure 5
). Make sure that any cable slack is above the ceiling
tile.

4. Pushing toward the ceiling tile, rotate the AP clockwise until the device clicks into place on the
ceiling tile rail.
5. On the AP-121 or AP-125, orient the antennas. For best results, rotate the antennas so that they are
vertical (perpendicular to the body of the AP) (see
Figure 6
).

Antenna Orientation on a Ceiling-Mounted AP-121/AP-125
On the AP-120 or AP-124, install the external antennas according to the manufacturer’s instructions,
and connect the antennas to the antenna interfaces on the AP (see
Figure 4
).
!
CAUTION
Make sure the AP fits securely on the ceiling tile rail when hanging the device from the ceiling,
because poor installation could cause it to fall onto people or equipment.
