Chapter 4: The SmartPath AP (LWN602A) Overview
• Yellow: The default route is through a backhaul Wi-Fi interface, but not all conditions for normal operations (white) have been
met.
• White: The device is powered on and the firmware is operating normally; that is, a wireless interface in access mode is up,
a wired or wireless backhaul link is up, and the SmartPath AP has a CAPWAP connection to either SmartPath EMS VMA or a
management AP.
• Purple: A new image is being loaded from SmartPath EMS VMA 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 SmartPath EMS VMA, choose the brightness level
that you want from the LED Brightness drop-down list on the 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
4-2.

4.4 Antennas
Antennas are an integral part of the SmartPath AP (LWN602A). The SmartPath AP LWN602A 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 cover
-
age in all directions in a cardioid (heart-shaped) pattern around each antenna (see Figure 2-1).
On the SmartPath AP LWN602A, 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. The relationship of antennas and radios is shown in Figure 4-3.
