Note:

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.

Condition

Green, constant

Normal operation, status OK

IP-IO module firmware application running

Green, flashing (~1 Hz)

Device restarting, wait

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.

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.

Important:

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.
