ServeRAID For ServeRAID error codes and procedures, refer to the Hardware Maintenance Manual for the particular RAID adapter in the system being serviced. Undetermined problems You are here because the diagnostic tests did not identify the failure, the Devices List is incorrect, or the system is inoperative. Note: A corrupt CMOS can cause undetermined problems. If power problems are suspected: 1. Power-off the computer. 2. Be sure the system is cabled correctly. 3. Remove or disconnect the following (one at a time) until you find the failure (power-on the computer and reconfigure each time). v Any external devices v Modem, printer, mouse, or non-IBM devices v Each adapter v Drives v Memory Modules (Minimum requirement = one 128 MB DIMM) Note: Minimum operating requirements are: a. 1 Power Supply b. System Board c. 1 Microprocessor d. 1 Terminator Card in Slot 2 e. 1 Memory Module (minimum of 1 DIMM in slot labeled DIMM 1) 4. Power-on the computer. If the problem remains, suspect the following FRUs in the order listed: Power Supply System Board Notes: 1. If the problem goes away when you remove an adapter from the system, and replacing that adapter does not correct the problem, suspect the system board, then the power supply. 2. If you suspect a networking problem and all the system tests pass, suspect a network cabling problem external to the system. Symptom-to-FRU index 97

ServeRAID
For
ServeRAID
error
codes
and
procedures,
refer
to
the
Hardware
Maintenance
Manual
for
the
particular
RAID
adapter
in
the
system
being
serviced.
Undetermined
problems
You
are
here
because
the
diagnostic
tests
did
not
identify
the
failure,
the
Devices
List
is
incorrect,
or
the
system
is
inoperative.
Note:
A
corrupt
CMOS
can
cause
undetermined
problems.
If
power
problems
are
suspected:
1.
Power-off
the
computer.
2.
Be
sure
the
system
is
cabled
correctly.
3.
Remove
or
disconnect
the
following
(one
at
a
time)
until
you
find
the
failure
(power-on
the
computer
and
reconfigure
each
time).
v
Any
external
devices
v
Modem,
printer,
mouse,
or
non-IBM
devices
v
Each
adapter
v
Drives
v
Memory
Modules
(Minimum
requirement
=
one
128
MB
DIMM)
Note:
Minimum
operating
requirements
are:
a.
1
Power
Supply
b.
System
Board
c.
1
Microprocessor
d.
1
Terminator
Card
in
Slot
2
e.
1
Memory
Module
(minimum
of
1
DIMM
in
slot
labeled
DIMM
1)
4.
Power-on
the
computer.
If
the
problem
remains,
suspect
the
following
FRUs
in
the
order
listed:
Power
Supply
System
Board
Notes:
1.
If
the
problem
goes
away
when
you
remove
an
adapter
from
the
system,
and
replacing
that
adapter
does
not
correct
the
problem,
suspect
the
system
board,
then
the
power
supply.
2.
If
you
suspect
a
networking
problem
and
all
the
system
tests
pass,
suspect
a
network
cabling
problem
external
to
the
system.
