246B
I/O adapter failed. Use the service processor menus
described in "Chapter 7. Service Processor Menus" on
page 447 to view the "Progress Indicators from Last
Boot" panel. If an E5xy checkpoint is recorded as the
first or second entry, the drawer and slot at the time of
failure can be determined from the E5xy checkpoint
information found on page 154. Use this information
when proceeding to "MAP 1540: Minimum Configuration"
on page 117.
2470
Problem could be propagated from the attached
Input/Output devices. Go to "MAP 1540: Minimum
Configuration" on page 117 and attempt to isolate the
problem. If MAP 1540 fails to isolate the problem, return
here and continue below.
After returning from "MAP 1540: Minimum Configuration"
on page 117, the problem could be the JTAG cable or
the system backplane assembly. Before replacing any
parts, test for the existence of the proper number and
position of memory cards and processor cards. This
condition may result in invalid configurations during VPD
reading.
Note: Record function 13 codes. Contact your second
level of support before replacing the system backplane
assembly.
247F
Main storage failure
A memory card at the specified location is faulty.
Probability is mandatory.
Record function code 19 from the operator panel. This
function code is the CCIN identifier, which is used to
determine the processor or memory card type. To get the
part number for the failing card, find the CCIN number in
the parts tables under "Electronic Cards" on page 556.
2480
Clock/processor regulator card at the specified location
is faulty. Probability is mandatory.
2481
