Procedures in the iSeries Service Functions
b. On the next display, enter the line description name for the communications line that has the
remote power-on cable attached.
c. Select Cable test from the display that shows a list of tests that can be performed on a

d. Follow all instructions (such as run problem analysis or attach the wrap connector).
Did you find the communications problem using the above procedure?
v No: Continue with the next step.
v Yes: Perform the following:
a. Exchange the failing item indicated (see Remove and replace procedures).
b. Verify that an IPL from a remote location completes successfully by going to step 5 (See page
24).
10. Find an entry in the Service Action Log that matches the time, SRC, and/or resource that compares
to the reported problem.
a. On the command line, enter the Start System Service Tools command (STRSST).
If you cannot get to SST, select DST (see Accessing Dedicated Service Tools in the iSeries
Service Functions
Note: Do not IPL the system to get to DST.
b. On the Start Service Tools Sign On display, type in a User ID with QSRV authority and Password.
c. Select Start a Service Tool —> Hardware Service Manager —> Work with service action log.
d. On the Select Timeframe display, change the From: Date and Time to a date and time prior to
