Fans may take a long time to slow down after fan boosting Problem System fans that "boost" due to an increased processor temperature may not return to normal speed immediately after the processor temperature returns to normal. Implication If the system fans boost due to a high processor temperature, the BMC does not restore the fans to a normal speed until a similar amount of time spent in a boosted state passes. For example, if a high processor temperature caused the fans to boost for five minutes, the fans would not return to normal until five minutes after the processor temperature returned to normal. Status This erratum is fixed in BMC release 59 and later releases. Workaround The fans will return to normal speed over time. 8. System requires ~35 seconds after AC power is applied before the power button responds Problem The BMC requires approximately 35 seconds to fully initialize the system after an AC cycle before the system can be powered on. Implication After an AC cycle, a user must wait approximately 35 seconds before the power button responds. The BMC causes the front panel LED to blink in an alternating amber/green pattern while the BMC initialization is in progress. Users should wait until the LED stops blinking in this pattern before pressing the power button. Status This erratum is fixed in BMC release 50 and later releases. Workaround None. 9. SEL events for Hot-swap Controller (HSC) may appear after a DC cycle Problem The HSC may log critical and non-critical temperature events in the SEL after a DC cycle. Implication The SEL events are "deassertion" events, which are not an indication of a problem with the system. Users can ignore these events as they are not errors or an indication of a problem in the system. Status This erratum will be fixed in a future HSC firmware revision. Workaround None. 10. Fans may run faster than expected after exiting BIOS setup 7
