Procedure 2
Printer Port LED Check on Boot Mode
The printer port LED displays the IRT (Initial Reliability Test) 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 parallel port of the Advanced Port Replicator 2001.
2. Read the LED status from left to right as you are facing the back of the computer.
3. Convert the status from binary to hexadecimal notation.
4. If the final LED status is FFh (normal status), go to Procedure 4.
5. 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 B2
and halts, the IRT test has already completed the KBC initialization. In this instance, the
IRT indicates an error has been detected during the BIOS rewrite.
