Action: If all fan LEDs are solid green but the fans in the enclosure are operating at a higher speed than normal, then access more information from the OA or HP iLO. Review the FAN section in OA SHOW ALL to locate the fan zone that is consuming more FAN speed. Verify the virtual FAN value for the affected servers within that FAN zone that indicates which server is consuming a lot of FAN speed. Possible indicators could be either an outdated ROMBIOS or HP iLO firmware or a server repeatedly going through POST or reboot. If a single fan is operating at approximately 80% and the issue is resolved after resetting the OA, then upgrade to OA firmware 3.60 or later to resolve the issue. For more information, review the HP BladeSystem c-Class Enclosure Troubleshooting Guide on the HP website (http://www.hp.com/go/bladesystem/documentation). HP Trusted Platform Module problems Action: If the TPM fails and is no longer detected by RBSU, request a new system board and TPM board from an HP authorized service provider ("Contacting HP technical support or an authorized reseller" on page 84). CAUTION: Any attempt to remove an installed TPM from the system board breaks or disfigures the TPM security rivet. Upon locating a broken or disfigured rivet on an installed TPM, administrators should consider the system compromised and take appropriate measures to ensure the integrity of the system data. When installing or replacing a TPM, observe the following guidelines: • Do not remove an installed TPM. Once installed, the TPM becomes a permanent part of the system board. • When installing or replacing hardware, HP service providers cannot enable the TPM or the encryption technology. For security reasons, only the customer can enable these features. • When returning a system board for service replacement, do not remove the TPM from the system board. When requested, HP Service provides a TPM with the spare system board. • Any attempt to remove an installed TPM from the system board breaks or disfigures the TPM security rivet. Upon locating a broken or disfigured rivet on an installed TPM, administrators should consider the system compromised and take appropriate measures to ensure the integrity of the system data. • When using BitLocker™, always retain the recovery key/password. The recovery key/password is required to enter Recovery Mode after BitLocker™ detects a possible compromise of system integrity. • HP is not liable for blocked data access caused by improper TPM use. For operating instructions, see the encryption technology feature documentation provided by the operating system. Memory problems General memory problems are occurring Action: • Isolate and minimize the memory configuration. Use care when handling DIMMs ("DIMM handling guidelines" on page 17). o Be sure the memory meets the server requirements and is installed as required by the server. Some servers may require that memory banks be populated fully or that all memory within a memory bank Hardware problems 48
