LEDs The LEDs on the AC 80 can be divided into three groups, i.e. bus
indicator LEDs, general purpose LEDs, and special purpose LEDs.
(Further information on the LEDs is given in
Chapter 5 – Diagnostics).
Figure 2-4 LEDs of the AC 80.
Bus Indicator LEDs These LEDs show the status of the fibre optic channels. The LEDs are
laid out in the same order as the optic terminals on the AC 80.
Note that the Rx LEDs light when data is received from the fibre optic
link. The Tx LEDs are controlled by the AC 80 itself.
Special Purpose LEDs F – Fault (red): This LED switches automatically on after the power-up
of the AC 80. The system application program also lights this LED if the
self test fails. In case of a serious hardware or program error, this LED
lights. Simultaneously, the general purpose LEDs indicate an error
code.
Note: The error codes are given in Chapter 5 – Diagnostics.
R – Run (green): This LED is lit when the system application starts to
run. It turns off upon serious hardware or program errors.
P – Power (green): This LED indicates that the power supply to the
AC 80 is good. The P LED is independent of system program status.
B – Battery (green): This LED indicates that the voltage level of the
battery is sufficient for backing up the internal real time clock and
buffered read/write memory. If no battery is inserted, or it is low, the B
LED is turned off.
T1, T2 (yellow): These LEDs indicate data being received on the
AF 100 channels 1 and 2 respectively. If the AC 80 is not connected to
AF 100, these LEDs are off. If the AC 80 is connected to the AF 100
with only one cable, one of the LEDs should be on, the other LED off.
