Troubleshooting

Troubleshooting Using the
LED Indicators

The ENI status LEDs provide a mechanism to determine the current
status of the ENI if a programming device is not present or available.
The LED behavior is described in the following table.

LED

Description

Color

State

Indicates

RS-232
TX/RX

RS-232 data
transmission indicator

green

flashing

data is being transmitted or received over the RS-232 port

off

no RS-232 traffic

POWER

module power

green

on

module is powered

off

module may not be powered

LINK

Ethernet link status

green

on

the module detects a valid Ethernet connection

off

the module does not detect a valid Ethernet connection

Ethernet
TX/RX

Ethernet data
transmission indicator

green

flashing steady

During normal operation (Fault LED is off) the Ethernet port is
transmitting or receiving NetLinx packets. For example, if you use
“Ping” or “Telnet”, the Ethernet TX/RX LED will not flash.

flash sequence

When the Fault LED is

on steady, the Ethernet TX/RX LED flashes

the following error codes:

•

ROM Error - 1 flash, then off

•

RAM Error - 2 flashes, then off

•

Net Controller Error - 3 flashes, then off

•

EEPROM error: 4 flashes, then off

•

Duplicate IP: 5 flashes, then off

When the FAULT LED is

flashing, the Ethernet TX/RX LED flashes

the following error codes:

•

Faulty Network Connection: 4 flashes, then off

•

ENI Not Configured: 5 flashes, then off

•

Unspecified Fault: off

off

no Ethernet traffic

FAULT

fault condition indicator red

on

lit when a fault condition is present, possible causes

•

ROM Checksum Error

•

RAM Test Error

•

Network Controller Error

•

EEPROM Checksum Error

•

Duplicate IP

(see Ethernet TX/RX LED behavior above for error codes)

flashing

one of the following:

•

faulty network connection

•

ENI does not have a valid IP address

off

hardware is functioning normally
