— When A Port and B Port are connected, their respected port number will
light and the center "A-B" LED will also be on.
If a Test Port display LED is bright yellow, this is an error state indication in
which a set of switch commands has configured the A and B Port to the same
Test Port. For example, sending command a1p1 then b2p1 to the Test Set
,
the Port Status LED display will show Port A 1 (green), Port B2 (amber), and
Test Port 1 (bright yellow). To avoid this switch configuration error, do not
send switch commands that select the same Test Port.
