Status LED A, B
The status LED A and B are of interest in case of troubleshooting.
A: yellow status LED
• A lit yellow LED indicates that the test set is ready to be controlled by a
computer. The hardware checks in the test set are finished, and the test
set is properly connected to a computer or a network.
• The LED is off when the test set is waiting for an "emergency software
image download". This is the case when pressing the ! button while
powering-up the CMC test set.
B: green LED
If the yellow LED A is off, the green LED B signals the following conditions:
• LED B blinks slowly:
CMC test set waits for the TFTP download (Trivial File Transfer Protocol)
of a software image.
• LED B is lit:
The TFTP download of the software image is in progress.
• LED B blinks quickly:
The computer writes (e.g., the software image) to the flash memory of
the CMC test set. Do not turn off the CMC test set as long as the writing
is in progress.
5.2.2 Ethernet / Network Settings
General
The OMICRON Test Universe software running on the PC communicates
with the CMC 353 via a network connection. Therefore it is possible to either
have the CMC 353 directly connected to the computer’s network plug by a
cable or to have the CMC 353 and the controlling computer connected to a
computer network.
Both network ports can be used interchangeably, but ETH1 is primarily used
to connect to a PC to control the test set and ETH2 for substation
communication. Both network ports have link LEDs (green) and traffic LEDs
(yellow flashing) to check the physical connectivity and proper cabling.
IP Configuration
For communication of the CMC 353 with the controlling PC the test set and
the OMICRON Test Universe software use a DCOM connection over
