hi all, is it possible to tell from the LED sequences, whether or not an MCK 1000 switch module is good?

i've tested several of them and have one at my desk right now where the led sequence is yellow, red, yellow, yellow.

i've tested other switch modules where the led sequence is yellow, red, green.

so i don't know if some of them are bad or if the led's are supposed to be different.

if you've worked on these, can u give me your 2 cents?
