Undetermined problems You are here because the diagnostic tests did not identify the failure or because the system is inoperative. If you suspect that a software problem is causing failures (continuous or intermittent), see "Error symptoms" on page 230.. Damaged data in CMOS memory or damaged BIOS code can cause undetermined problems. If you suspect that the BIOS code is damaged, see "Recovering BIOS code" on page 75. Check the LEDs on all the power supplies (see "Power LED errors" on page 240). If the LEDs indicate the power supplies are working correctly, return here and do the following: 1. Power-off the server. 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). Note: For 16-way configuration, turn on each chassis as a standalone (see "Starting the diagnostic programs" on page 70). v Any external devices v Surge suppressor device (on the computer) v Modem, printer, mouse, or non-IBM devices v Each adapter v Hard disk drives v Memory modules (minimum requirement = 1 GB (4 x 512 MB DIMMs)) Note: Minimum operating requirements are: a. 1 microprocessor with VRM b. 2 x 512 MB DIMMs c. 1 power supply d. Top power board e. 1 SMP board f. Center plane g. I/O board h. PCI-X board 4. Power-on the computer. If the problem remains, suspect the following FRUs in the order listed: Note: For 16-way configuration, turn on each chassis as a standalone server (see "Starting the diagnostic programs" on page 70). v SMP board v Center plane v PCI-X board v I/O 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 PCI-X board. 2. If you suspect a networking problem and all the system tests pass, suspect a network cabling problem external to the system. 246 xSeries 445 Type 8870: Hardware Maintenance Manual and Troubleshooting Guide
