Troubleshooting System problems

Resolving The Problem

Affected configurations

• IBM eServer xSeries 130, 135, 330, and IBM IntelliStation R Pro

This document is intended for trained servicers who are familiar with IBM server and workstation products. Use this document along with advanced diagnostic tests to troubleshoot problems effectively. Before servicing an IBM product, be sure to review the safety information. Click here to review the safety information.

This document contains information if the diagnostic tests did not identify the failure, the Devices List is incorrect, or the system is inoperative for undetermined system problems. If this has occurred proceed as follows:

Note: A corrupt CMOS can cause undetermined problems.

1. Ensure that the system is connected to an AC power source.
2. Press the power switch.
   
   Note: If AC power has been removed from system, allow 30 seconds after restoring AC power before pressing power control button. If system was powered-on when AC power was removed, system should restart automatically when AC power is restored.
   
   
3. Are the power indicator LEDs (front and rear) ON or blinking?
   1. No, check AC power into system. If AC power into system is good, suspect the following FRUs in the order listed:
      1. Power supply
      2. System board
         
         
   2. Yes, power indicators (front and rear) are blinking. Turn switch 5 on switch block 1 to ON.
      If system powers-on, turn switch 5 on switch block 1 to OFF and replace front panel assembly. If system does not power-on, reconfigure system to minimum operating requirements and retry. If problem remains, suspect the following FRUs in the order listed:
      1. Power supply
      2. System board
         
         
   3. Yes, power indicator LEDs (front and rear) are ON.
      1. Power-off system.
      2. Ensure system is cabled correctly.
      3. Reconfigure system to minimum operating requirements.
         
         Note:Minimum operating requirements
         Power supply
         System board
         Microprocessor
         Terminator card
         Memory module (with a minimum of 128 MB DIMM)
         
         
      4. Power-on system.
         If problem remains, suspect the following FRUs in the order listed: power supply and system board. If problem goes away, replace removed items one at a time until failing item is found (power-on and reconfigure system each time).
         

Note: 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. If you suspect a networking problem and all the system tests pass, suspect a network cabling problem external to the system.
