Antennas; Mounting An Ap110 Or Ap120 - Aerohive AP120 Hardware Reference Manual

Chapter 1 AP110 and AP120 Platforms
White
• : The device is powered on and the firmware is operating normally; that is, the AP has made a
CAPWAP connection to either HiveManager or a management AP.
Purple
• : A new image is being loaded from HiveManager or a management AP.
Orange
• : An alarm indicating a firmware or hardware issue has occurred.
For locations where the status indicator might be a distraction or attract unwanted attention, you can adjust
its brightness level from bright (the default) to soft to dim. You can even turn it off completely. In
HiveManager, choose the brightness level that you want from the LED Brightness drop-down list on the
Configuration > Advanced Configuration > Management Services > Management Options page. Through
the CLI, enter [ no ] system led brightness { soft | dim | off }. The four settings are represented
graphically in Figure 2.

Antennas

Antennas are an integral part of both the AP110 and AP120. The AP110 has two internal dual-band
antennas. The AP120 has four internal single-band antennas. Two of the antennas operate in the 2.4-GHz
band (IEEE 802.11b/g/n) and have a 0-dBi gain. The other two antennas operate in the 5-GHz band (IEEE
802.11a/n) and have a 3-dBi gain. All antennas are omnidirectional, providing fairly equal coverage in all
directions in a cardioid (heart-shaped) pattern around each antenna (see
On the AP110, the two dual-band antennas link to a dual-band radio, which can operate in the 2.4-GHz
band for 802.11b/g/n or the 5-GHz band for 802.11a/n, but not in both bands simultaneously. On the AP120,
the two 2.4-GHz antennas link to one radio, and the two 5-GHz antennas link to the other radio, both of
which can operate concurrently. Conceptually, the relationship of antennas and radios is shown in

Using one of the track clips included in the box with the AP, you can mount it to a track in a dropped ceiling
grid. To mount the AP to any flat surface that can support its weight (1.75 lb., 0.8 kg), use two #6 or #8 screws
to mount it on a wall and three screws to mount it on a ceiling.
You can also mount the AP on a table using the four rubber feet that ship with the product. Simply
peel the feet off the adhesive sheet and press one against each underside corner of the device.
