5. Perform the following:
a. Dial the telephone number for the system.
b. Wait at least two minutes for the system to answer.
Note: The Ring Indicator signal is used to start the remote IPL. If the caller hangs up the telephone
before the system disconnects the line (indicated by the return of the dial tone), the IPL will not
complete. The caller may hear other tones before the dial tone.
Was the telephone answered in two minutes?
v Yes: Does the IPL complete successfully?
– No: Continue with the next step.
– Yes: This ends the procedure.
v No: Continue with the next step.
6. The IPL from a remote location was not successful. The following steps show you how to start a
manual IPL and how to analyze the remote IPL problem.
Select Manual or Normal mode on the control panel.
Note: If you want the Use Dedicated Service Tools (DST) display shown after the IPL, select Manual
mode on the control panel.
Start an IPL by powering on the system (see Power on/off the system and logical partitions).
Does the IPL complete successfully?
v Yes: Continue with the next step.
v No: Go to "Starting point for all problems" on page 2.
This ends the procedure.
7. Did you verify that the operating system has the correct value of 1 for the remote power-on function
in step 2 (See page 23)?
v No: Continue with the next step.
v Yes: Go to step 9 (See page 24).
8. On the command line, enter the Display System Value command:
DSPSYSVAL QRMTIPL
Does the operating system have the correct value of 1 for the remote power-on function?
