Chapter 1: Overview
ITS Core AP Status LEDs
The ITS Core AP provides the following status LEDs.
W
ired/Ethernet Activity - The Core AP provides two LEDs to indicate wired/
Ethernet activity to the ITS infrastructure. During normal operation, these LEDs
indicate the following information:
- L
ink LED - Link present/Ethernet connection. Lights GREEN (ON) when a
pass-through link is present - OFF when not present.
- A
ct LED - Wired network activity. Flashes YELLOW (ON) when there is activity
is over the wired network.
W
ireless/RF Activity - The Core AP provides three LEDs to indicate wireless/RF
activity. During normal operation, these LEDs indicate the following information:
- P
ower/Sync LED - GREEN (ON) when power and synchronization signal is
present.
- R
adio LED - Normally OFF (not lit) - flashes green to indicate wireless network
activity.
- N
etwork LED - Normally OFF (not lit) - flashes green to indicate wired network
activity.
At initial power on the AP runs a Power On Self-Test (POST). During the POST, the
above LEDs indicators flicker and then all three will illuminate continuously
(AMBER) to indicate correct startup operation. Then, the Power ON LED will
illuminate (GREEN) continuously to indicate that the 48Vdc power and sync
signal are being supplied, and the other two (AMBER) LEDs turn off (not lit).
R
emote Antenna - The Core AP provides two LEDs on each RJ-45 UTP cable
connector that provides status on a connected Remote Antenna:
- R
A Connection - Lights GREEN to indicate a RA is connected to the Core AP.
- R
A Power - Lights YELLOW to indicate connected RA is receiving power from
the Core AP.
Remote Antenna Status LEDs
The Remote Antenna provides the following status LEDs.
Remote Antenna Status LEDs - The green and yellow LEDs above the
RJ-45 UTP cable connector to the Core AP provide status on the Remote
Antenna as summarized below.
Table 1-2: Remote Antenna Status LEDs
Green/Yellow LEDs Remote Antenna Status
Off/Off No connection to or power from Core AP/Self-test Failed.
Flash Green/Yellow Remote Antenna is running self-test/Power on.
Solid Green/Yellow Connection to Core AP is Successful/Power On.
This is the expected normal operational status.
