v Follow the suggested actions in the order in which they are listed in the Action column until the problem is
solved.
v
See Chapter 4, “Parts listing, Types 7871 and 1949,” on page 41 to determine which components are CRUs and
which components are FRUs.
v If an action step is preceded by “(Trained service technician only),” that step must be performed only by a
trained service technician.

Description Action
Microprocessor
error The microprocessor has failed or overheated,
or the start microprocessor is missing.
1. Check the AMM event logs.
2. If the log shows that a microprocessor is
disabled or that a microprocessor error has
occurred, perform one of the following
actions:
a. (Trained service technician only) Reseat
the microprocessor that is indicated by
the lit LED. See “Removing a
microprocessor and heat sink” on page
85 and “Installing a microprocessor and
heat sink” on page 88.
b.
(Trained service technician only)
Replace the microprocessor that is
indicated by the lit LED. See
“Removing a microprocessor and heat
sink” on page 85 and “Installing a
microprocessor and heat sink” on page
88.
MIS Microprocessor mismatch. Make sure that microprocessors 1 and 2 are
identical (number of cores, cache size and
type, clock speed, internal and external clock
frequencies).
1.
Verify the type of microprocessors installed
by using the Configuration/Setup utility.
See “Using the Setup utility” on page 20.
2. (Trained service technician only) Replace
microprocessor 2 with an identical
microprocessor to microprocessor 1. See
“Removing a microprocessor and heat
sink” on page 85 and “Installing a
microprocessor and heat sink” on page 88.
NMI (NMI error) The system board has failed.
1. Replace the blade server cover, reinsert the
blade server in the BladeCenter unit, and
then restart the blade server. Check the
BMC log for information about the error.
See “Using the Setup utility” on page 20.
2. (Trained service technician only) Replace
the system-board assembly - See
“Removing the system-board assembly” on
page 94 and “Installing the system-board
assembly” on page 95.
SAS storage drive
error A storage drive has failed. Run the SAS Attached Disk diagnostic test. If
the drives passes diagnostics but continues to
have a problem, replace the storage drive with
a new one. See “Dynamic system analysis
diagnostic programs and messages” on page
185.
