IBM 8688 log, entries

Level 2 Light Path LED FRU/action
VRM LED on (VRM failure)
1. See the system-error log.
2. Microprocessor power module 1-4.
Note: To see microprocessor error LEDs, remove the processor-board
assembly from the chassis, and press the LED Activation switch.
3. VRM 1-4.
4. Midplane-board VRM.
5. Processor-board VRM.
6. Processor board.
7. Midplane board.
Non Redund (nonredundancy lost)
1. Connect the server to 220v ac if power redundancy is required.
2. If the PSx LED is lit on Level 2 Light Path, follow the instructions for that
LED.
3. Replace failing power supply.
Over Spec (power supplies’ rating
exceeded)
1. Ensure that ac power is applied to both power supplies.
2. Power supply.
VRM and memory LEDs on
(memory board level 3 LED on)
1. Replace the failing VRM with lit LED, and re-enable any failed memory.
2. Memory board.
3. Midplane board.
Level 2 VRM LED on and board
LED on
1. Processor-board VRM.
2. Remove all PCI adapters from the server.
3. PCI-X board VRM.
4. PCI-X board.
System-error log entries
The system-error log is similar to an event log and can contain messages of three
major types:
Information Information messages do not require action and record significant
system-level events. Example: ’System Complex Powered Up’
Warning Warning messages indicate possible problems but do not require
immediate action. Example: ’System over recommended ambient
temperature’
Error Error messages indicate system errors that may require attention.
Example: ’Fan 2 not detected’
System-error log messages can originate from two sources.
v SAL/EFI
v Service processor
Each
entry contains date and time information, which is useful in determining the
nature of the occurrence.
