3e Technologies International Inc. 527A3 User Manual

The top panel of the 3e–527A3 contains a set of indicator lights (Light 

Emitting Diodes or LEDs) that help describe the state of various network-

ing and connection operations.

Power

The Power indicator LED indicates when the device is powered on.  If 

this light is on, the gateway is on; if it is not on, the gateway is off. 

WAN

This light indicates the state of your connection to the organization's 

Ethernet LAN network.  When on, the WAN light indicates that the 

gateway is connected to the network.  When the WAN light is off, the 

gateway does not have an active connection to the network.

WLAN1 

Activity

1. LED Off means the RF power is adminstratively disabled.
2. LED steady on means RF power is enabled but there no traffic.
3. LED blinking is relative to user traffic.

WLAN2 

Activity

LED is used to indicate downlink traffic. It blinks when traffic is sent to 

(or received from) the downlink. 

•  Root node: on and blinks with traffic. 

•  Intermediate node: on and blinks with traffic.

•  Leaf node: always off.

WLAN Signal 

Strength

The Strength LED indicator indicates the strength of the node assigned 

in the Signal Strength MAC field of the Bridge Configuration screen. If 

there is no assignment, the strength of the uplink node is shown..

1. LED Off: means no connection on the bridge side, or the signal is 

very weak. 

2. LED blinks slowly (every 1 second): means there is a connection, and 

the signal quality is poor. 

3. LED blinks fast: means there is a connection, and the signal quality 

is good. 

4. LED steady on: means there is a connection, and the signal quality is 

excellent.

FIPS/MODE
(WLAN2 

Usage)

LED is used to indicate uplink traffic. It blinks when traffic is sent to (or 

received from) the uplink.

•  Root node: always off

•  Intermediate node: on and blinks with traffic.

•  Leaf node: on and blinks with traffic.

NOTE:  for a standalone bridge, technically it’s root and leaf. But we 

define it as root, not leaf. So the WLAN 2 LED will be solid on. FIPS/

MODE LED will be off. When high bandwidth traffic is going through, 

the response of the traffic LED indicators may be slow due to the work 

load of the internal processor.
