IP-IO Module LEDs
There are three LEDs on the front panel of the IP-IO module.

Ethernet 2 |
Green/Yellow |
The IP-IO module Ethernet and Status indicators comprise two LEDs (green/yellow and green/red respectively) in one structure.
The LEDs indicate status of the IP-IO module and the ongoing communication.
Status LED
The IP-IO module Status LED indicates the condition of the device.

LED Patterns |
Condition |
|
Green, constant |
Normal operation, status OK IP-IO module firmware application running |
|
Green, flashing (~1 Hz) |
Device restarting, wait IP-IO module firmware application running |
|
Red, constant |
Detected error, attention required |
|
Red, flashing (~1 Hz) |
Device operates, but a problem needs attention |
|
Red/green, flashing (~1 Hz) |
IP-IO module I/O board receiving software upgrade, wait Do not interrupt power to the I/O module. For more information, see the following Important note. |
|
Amber, constant |
IP-IO module firmware boot applet running |
|
Amber, flash |
Device restarting, wait IP-IO module firmware boot applet started |
|
Amber/green, flashing (~1 Hz) |
IP-IO module firmware is being upgraded. It is typically the firmware main application, but it can also be a boot applet. |
Avoid power interruptions to the device during the brief period when the Status LED is flashing red and green. An interruption causes problems with the I/O processor upgrade and can result in corrupt firmware. You can view the evidence of a corrupt processor when the device reports itself as an “MP-C-15A.” A corrupt I/O processor can lead to the loss of the reset button and/or I/O functionality, as well as the inability to upgrade the I/O processor and/or the device.
Ethernet LEDs
The Ethernet (1 and 2) LEDs indicate the condition of the Ethernet communication.

Yellow, flashing |
100 Mbit communication |
|
Green/yellow, constant |
10/100 Mbit link connected, no activity |
|
No light |
No link, no activity |
