錯 誤 ! 尚 未 定 義 樣 式 。 EPSFunctional Specification3.26 Global Fan Fault LED<strong>Emerald</strong> <strong>Ridge</strong> platform has a Fan Fault LED located on front panel next to <strong>System</strong> Status LED,which indicates Fan Fault on system, since FAN LEDs are inside chassis, user can use thisLED to find out if there are any fan failures in the systemOn normal condition Global Fan Fault LED will be OFF. In case of fan fault (Any of system Fan),addition to relevant FAN fault LED, Global FAN fault LED will be amber solid,Global fan fault LED will be OFF only if NONE of system fan fault LED is ON and Global FanFault LED will be ON only if ANY of Fan fault LED is ON.None of other sensors and <strong>System</strong> status contributes to Global Fan Fault LEDIn case of fan fault when system is powered off ( DC off), Global Fan fault LED will be ON sothat user can see the fan fault without opening the chassis and it will be turned off till sensor isrearmed ( int agent in case of DC on)3.27 Power Management Bus (PMBus)The BMC firmware implements power-management features based on the Power ManagementBus (PMBus) 1.1 Specification.3.27.1 PMBus AddressingThe power supply device address locations are shown below.Table 13.
