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.
