Checkpoint Description
E1F7 No boot image located
E1FB Scan SCSI bus for attached
devices
E1FD The operator panel alternates
between the code E1FD and
another Exxx code, where Exxx is
the point at which the error
occurred.
Action/ Possible Failing FRU
Follow the repair actions listed for
error code 20EE000B.
If a location code is available,
follow the repair actions listed for
error code 21A000XX.
Checkpoint E1FD indicates that an
error has occurred during system
startup. The display alternates
between E1FD and another
checkpoint, Exxx, where the error
occurred. Check the list of
checkpoints for Exxx. If the
description for that checkpoint does
not resolve the problem, return here
for more instruction.
Checkpoint E1FD may be displayed
when an adapter or peripheral is
malfunctioning. To find which device
is most likely to have caused the
error, follow these steps.
1. Check the "progress codes from
last boot" in the service
processor's information menu.
Look for the last location code
that was displayed before the
E1FD error code.
2. The device pointed to by this
location is suspect.
3. If the progress code listing only
contains the E1FD and Exxx
checkpoints, restart the system
and power off when the E1FD
and Exxx codes are displayed.
Repeat step 1.
4. Try removing the suspect
device (if it is not integrated).
Remove power from the system
before changing the hardware
configuration.
5. Restart the system. If it now
boots normally, without stopping
at checkpoint E1FD, the device
that was removed in the
previous step should be
replaced.
6. If the above steps have not
resolved the problem, go to
"MAP 1540: Minimum
Configuration" on page 57.
