Four-Digit Display
This four-digit numeric display indicates the states of the internal link
state machine.
The two digits on the left represent the downstream link of the test card
(only in case of AIC Test Mode), the link between the test card and the
add-in card plugged onto it.
The two digits on the right represent the upstream link of the test card,
this is the link between the test card and the target platform.
When all links have been established successfully during boot up, the
display shows “1010” for AIC Test Mode. Topology Test Mode displays a
“T10”. All other numbers indicate an error.
The following table shows the link states represented by the individual
numbers:
