Error Code/Symptom FRU/Action I9990650 (AC power has been 1. Check cable restored) 2. Check for interruption of power supply 3. Power Cable (Virus warning) (Boot sector 1. Run Configuration/Setup has changed) 2. Run virus detection software Other numbers Follow instructions on screen. 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 Surge suppressor device (on the computer) 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 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 119

Error Code/Symptom
FRU/Action
I9990650
(AC power has been
restored)
1.
Check cable
2.
Check for interruption of power supply
3.
Power Cable
(Virus warning)
(Boot sector
has changed)
1.
Run Configuration/Setup
2.
Run virus detection software
Other numbers
Follow instructions on screen.
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
Surge suppressor device (on the computer)
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 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.
