v A defective device is causing another device not to be recognized. v The SCSI controller failed (on the system board or SCSI adapter). v Use the procedure in "Undetermined problems" on page 75 to find the problem. If a device is missing from the list, replace it. If this does not correct the problem, use the procedure in "Undetermined problems" on page 75. Memory Diagnostic tests The Memory Diagnostics provide the capability to identify a particular memory module (SIMM or DIMM) which fails during testing. Use the System Board Layout section to reference the memory sockets, or select F1 twice to load the Diagnostics online manual and select ″SIMM/DIMM/RIMM Locator″. Follow the steps below to locate the Memory Diagnostic tests options. 1. Select the DIAGNOSTICS option on the toolbar and press Enter. 2. Highlight either the Memory Test-Full or Memory Test-Quick option and press Enter. 3. v Memory Test-Full The full memory test will take about 80 seconds per MB of memory and will detect marginal, intermittent, and solid (stuck) memory failures. v Memory Test-Quick The quick memory test will take about 20 seconds per MB of memory and will detect solid (stuck) memory failures only. Notes: v Either level of memory testing can be performed on all memory or a single SIMM or DIMM socket. v Only sockets containing a SIMM or DIMM can be selected for testing. Unpopulated sockets are noted by ........ beside the test description. Alert-On LAN™ test The Alert On LAN test does the following: v Determines if Alert On LAN is supported on the system. v Checks the revision ID register. v Verifies the EEPROM checksum. v Validates that a software alert can be sent. Asset ID™ test The Asset ID test does the following: v Determines if Asset ID is supported on the system. v Verifies the EEPROM areas. v Performs an antenna detection test. Test results Diagnostic test results will produce the following error code format: Function Code Failure Type DeviceID Date ChkDigits Text 10 Hardware Maintenance Manual A40 Type 6840 A40P Type 6841 A40i Type 2271: IBM NetVista Computer
