Procedure 2
Printer Port LED Check on Boot Mode
The printer port LED displays the IRT status and test status by turning lights on and off as an
eight-digit binary value for boot mode. Figure 2-2 shows the printer port LED.
Figure 2-2 Printer port LED
To use the printer port LED follow the steps below:
1. Plug the printer port LED into the computer’s parallel port.
2. Turn on the computer’s power.
3. Read the LED status from left to right as you are facing the back of the computer.
4. Convert the status from binary to hexadecimal notation.
5. If the final LED status is FFh (normal status), go to Procedure 3.
6. If the final LED status matches any of the test status values in Table 2-3, perform Check
1.
NOTE
: If an error condition is detected by the IRT test, the printer port LED displays an
error code after the IRT test ends. For example, when the printer port LED displays 19h and
halts, the IRT test has already completed the Display initialization. In this instance, the IRT
indicates an error has been detected during the Display logo.
