H132745 - 3Com 3C509 Adapter may not Configure in 6576 SYMPTOM: 3Com 3C509-B-TPO Ethernet adapter may not configure in an IBM PC 300 Series 6576 with the Configuration/Diagnostics software that ships with the adapter. PROBLEM ISOLATION AIDS: The Configuration/Diagnostic software does recognize the 3Com adapter in the system. FIX: If possible, verify that the adapter fails in other "Like" systems, such as another IBM PC 300 6576. If the adapter DOES fail in another system, verify that the installation instructions from the manufacturer are being followed correctly and replace the adapter. If the adapter cannot be tested in another system, verify that the installation of the 3Com adapter is being done according to the manufacturers instructions. Obtain a replacement 6576 riser card and 3COM adapter for diagnostic purposes. Retest the installation. If the failure persists, continue normal problem determination to isolate the failing FRU. 3Com is a trademark of the 3Com Corporation.
