The following table describes the meanings of each LED on the SNE. The normal states are in bold. A flicker has a fast blink rate (faster than one second) whereas a flash has a much slower blink rate (one second or more).

Table 1. Network Engine LEDs designation, normal status, description, and other conditions

LED Name

Color

State

Description

HEARTBEAT

Multicolor: blue or purple

Flashing blue and purple

1 blink per second = Normal operating status (all monitored processes have started and the device is fully operational)

On, blue

On solid, no blink = SNE is supplied with power but not operational

Medium flicker, purple and blue

2 blinks per second = SNE is starting up

Fast flicker, purple and blue

5 blinks per second = SNE is shutting down

Off

No power applied

FAULT

Red

Off

No faults; normal operation

On

On steady = Diagnostics are running or fault conditions are detected (for example, excessive memory or flash usage, or high CPU temperature).

ETH ACTIVITY

Green

Flickering

1 blink per second = Data is transferring over the Ethernet connection. Ethernet traffic is general traffic (may not be for the network engine).

Off

No communication

ETH LINK SPEED

Blue or yellow

On

On steady, blue = Network is connected at 1000 Mbps

On steady, yellow = Network is connected at 100 Mbps

Off

No network connection or if ETH ACTIVITY light is flickering, network is connected at 10 Mbps.

SITE DIRECTOR

Green

On

On steady = Network engine is a site director

Off

Network engine is a child device

BACNET/IP

Green

Flashing

1 blink per second = The SNE is transmitting BACnet messages over BACnet/IP to other devices, including other engines.
Note: If you select the setting SC Only, the light flashes but the messages use the BACnet/SC datalink, not BACnet/IP.

Off

No communication with other BACnet/IP devices

USB-1

Green or Red

On

Solid red = An unsupported device is connected to USB-1

Note: Only approved USB adapters that have been tested and qualified function with the SNE. Non-qualified adapters do not function with the SNE. Refer to SNE/SNC Product Bulletin (LIT-12013296) for more information.

Flashing Green

1 blink per second = A supported device is connected to the SNE over USB-1 port.

Off

No device is connected or the USB port is disabled.

USB-2

Green or Red

On

Solid red = An unsupported device is connected to USB-2

Note: Only approved USB adapters that have been tested and qualified function with the SNE. Non-qualified adapters do not function with the SNE. Refer to SNE/SNC Product Bulletin (LIT-12013296) for more information.

Flashing Green

1 blink per second = A supported device is connected to the SNE over USB-2 port.

Off

No device is connected or the USB port is disabled.

FC BUS-1

Green

Flashing

1 blink per second = data transmission with normal communication over FC BUS-1

On

Network engines are defined on FC BUS-1, but none are communicating. Only the SNE is transmitting.

Off

No data transmission

FC BUS-2

Green

Flashing

1 blink per second = data transmission with normal communication over FC BUS-2

On

Network engines are defined on FC BUS-2, but none are communicating. Only the SNE is transmitting.

Off

No data transmission

FC EOL-1

Yellow

On if connected

On Steady = end-of-line termination is set to on for FC BUS-1

Off if not connected

Off Steady = end-of-line termination is set to off for FC BUS-1

FC EOL-2

Yellow

On if connected

On Steady = end-of-line termination is set to on for FC BUS-2

Off if not connected

Off Steady = end-of-line termination is set to off for FC BUS-2
