8 Self-Test
The R&S TS-PIO2 has a built-in self-test capability. The following tests are implemen-
ted:
●
LED-Test
●
Power-on test
●
TSVP Self-Test
8.1 LED Test
After power-on, all three LED's light up for around three seconds to indicate that the
5
V supply is present and all LED's are working. The following statements can be made
about the different LED states:
Table 8-1: Statements about the LED Test
LED
Description
One LED does not
light up
Hardware problem on the module
LED faulty
No LED's light up
No +5 V supply
8.2 Power on test
The power on test runs in parallel to the LED test. If a fault is discovered in the module,
the red LED will light up to indicate the fault. The test is limited to checking the cPCI
interface and the firmware of the R&S TSPIO2. Note the following statements describ-
ing the different display states of the red and green LED after the LED test has been
performed:
Table 8-2: Observations about the power on test
LED
Description
PWR LED (green) on
All power supply voltages are present
PWR LED (green) off
At least one power supply of module R&S TS-PIO2 or module R&S TS-PDC is
not present
ERR LED (red) off
No error is present
ERR LED (red) is lit or
flashing
Hardware error is present (processor is not starting)
If diagnostic results indicate a faulty power supply, perform a visual inspection of the
LEDs on the corresponding Rear-I/O module R&S TS-PDC. If the results confirm that
the power supply voltage has failed, the R&S TS-PDC module must be replaced.
