2-1-3 LED Indicators
The following table shows the meaning of the Unit’s TS and I/O indicators,
which are common to all of the Slice I/O Units.
The ERR indicators show errors specific to the Unit, such as I/O errors. Any
numbers that immediately follow “ERR” indicate the channel number, e.g.
ERR0 indicates a Unit that has an error in channel 0.
