v Make sure that the device drivers on the client and server are using the same protocol. If the Ethernet controller still cannot connect to the network but the hardware appears to be working, the network administrator must investigate other possible causes of the error. Solving undetermined problems If the diagnostic tests did not diagnose the failure or if the server is inoperative, use the information in this section. If you suspect that a software problem is causing failures (continuous or intermittent), see "Software problems" on page 137. Damaged data in CMOS memory or damaged BIOS code can cause undetermined problems. To reset the CMOS data, use the password override jumper to override the power-on password and clear the CMOS memory, see "System-board jumpers" on page 13. If you suspect that the BIOS code is damaged, see "Recovering the BIOS code" on page 156. Check the LEDs on all the power supplies (see "Power-supply LEDs" on page 142). If the LEDs indicate that the power supplies are working correctly, complete the following steps: 1. Turn off the server. 2. Make sure that the server is cabled correctly. 3. Remove or disconnect the following devices, one at a time, until you find the failure. Turn on the server and reconfigure it each time. v Any external devices. v Surge-suppressor device (on the server). v Modem, printer, mouse, and non-IBM devices. v Each adapter. v Hard disk drives. v Memory modules. The minimum configuration requirement is 1 GB (two 512 MB DIMM, in DIMM slots 1 and 2). v Service processor (Remote Supervisor Adapter II SlimLine). The following minimum configuration is required for the server to start: v One microprocessor v Two 512 MB DIMMs v One power supply v Power backplane v Power cord v ServeRAID SAS controller 4. Turn on the server. If the problem remains, suspect the following components in the following order: a. Power backplane b. Memory card (DIMM) c. System board If the problem is solved when you remove an adapter from the server but the problem recurs when you reinstall the same adapter, suspect the adapter; if the problem recurs when you replace the adapter with a different one, suspect the riser card.
