See Chapter 3, “Parts listing, Type 8878 and 8879,” on page 109 to determine which components are
customer replaceable units (CRU) and which components are field replaceable units (FRU).
v If an action step is preceded by “(Trained service technician only),” that step must be performed only by a
trained service technician.
Error code Description Action
201-198-000 Memory Test Aborted: Could not run the
test; suspect microprocessor tray error.
1. Restart the server.
2. Run the diagnostic test again.
3. Reinstall the diagnostic programs (see “Updating
the firmware” on page 151).
4. (Trained service technician only) Replace the

201-198-00n Memory Test Aborted: Could not run the
test.
Note: n = 1-9 (programming error).
1. Restart the server.
2. Run the diagnostic test again.
3. Reinstall the diagnostic programs (see “Updating
the firmware” on page 151).
201-xxx-CBN Failed Memory Test: See “Memory card and
memory module (DIMM)” on page 126.
v
C = memory card [1-4]
v
B = physical bank [1-2]
Note: Bank 1 = DIMMs 1 and 3; Bank 2
= DIMMs 2 and 4
v
N = failing DIMM [1-4]
1. Reseat the following components:
a. DIMM N
b. Memory card C
2. Replace the components listed in step 1 one at a
time, in the order shown, restarting the server
each time.
Note: N = 9 indicates both DIMMs in physical bank
B and memory card C.
