System and diagnostic LEDs The System Status LED on the front panel of the system and the four diagnostic LEDs on the rear panel of the system are ud for diagnosing the health of the system. The LEDs warn of impending hardware failures and allow you to take preventive action, such as making a system backup or replacing a component before it fails. The Diagnostic LEDs are labeled 1, 2, 3 and 4 on the rear panel. The location of red LEDs can be ud to identify the category of the fault or warning. For example, if LED one is red, there is a problem with memory. However, if LEDs one and two are both red, there is a problem with the system processor. The following symbols are ud in the LED tables. The System Status LED on the front panel of the system indicates the state of the system: - | Off indicates the system is off. | | Green indicates that the system is running normally. Blinking green indicates that the system is booting (slow blink 0.5 Hz). | | Blinking orange indicates a WARNING (medium blink 1.0 Hz). | | Blinking red indicates a FAULT (fast blink 1.5 Hz). | | |
The Diagnostic LEDs on the rear panel of the system provide details about each specific warning or fault: | Solid red indicates the failing part or sub-system | | Off or solid green diagnostic LEDs provide additional details about the failure | | |
The faults and warnings fall into the following general categories, each specific error is described in detail on the following tables. 古代军队编制LED1 | LED2 | LED3 | LED4 | Category | 夏雨落 | - | - | - | Memory | - | | - | - | Firmware | - | -- | | - | System Board | -初中英语单词大全 | - | - | | Fan | | | - | - | Processor | | - | | -千代田之松 | BMC | - | | | - | System | | - | - | | Temperature | - | | - | | Power | | | | | Unknown | | | | | | Warnings (System LED is Blinking Orange) | The following tables provide additional information about each specific warning associated with the various possible Diagnostic LED lighting quences when the system LED is orange (medium blink 1.0Hz). | LED1 | LED2 | LED3 | LED4 | Warning | Solution | Unknown Warnings | | | | | Unknown warning. | Contact your HP Support Engineer | Memory Warnings | | | - | - | Mismatched memory pairs. | Refer to the memory quence diagram. | | - | | | Memory load order error. | Refer to the memory quence diagram. | | | | | Can't detect memory type. | Contact your HP Support Engineer | System Board Warnings | | | | - | Battery voltage low. | Replace the system board battery. | Fan Warnings | - | | - | | Chassis fan not functioning properly. | Replace the fan that is not functioning.

System Board LEDs There are three additional LEDs that can help when troubleshooting the system. The LEDs are located on the system board clo to the back of the system and can be viewed through the small holes in the system ca just above the Diagnostics LEDs. LED | Description | 1 STBY | This standby LED comes on as soon as the system power cord is plugged in. If this LED is off when you plug the system in, check that the power cord is connected to the system and the outlet, and make sure the outlet is turned on. If this does not work, make sure the main and auxiliary cables are correctly plugged into the board. If the system is still not receiving power, test the power supply. | 2 BMC | A few conds after the system is plugged in this LED starts blinking, which means that the Baboard Management Controller is alive. If this LED is not blinking and the STBY (standby) LED is on, you may have to replace the system board. | 3 F/W | A few conds after the power button is presd in the system firmware code fetch LED comes on indicating that the firmware has started the boot process. If this LED does not come on, make sure: ∙The processor(s) are correctly ated. ∙Each processor power module is correctly mounted and connected to the corresponding power supply cable. ∙All appropriate power supply cables are properly connected to the system board. | | |
BCH Error and Warning Messages BCH error and warning messages are displayed on the console as part of the boot process. They can also be retrieved via the Warnings BCH command. Warnings and errors displayed are: WARNING: Processors are not installed in the correct order. WARNING: Setting DEFAULTS has failed. WARNING: Not enough error-free contiguous memory (GoodMem). WARNING: Memory page deallocation has been disabled becau the Page Deallocation Table (PDT) is full. ERROR: Current loading of DIMMs failed the loading order check. WARNING: The Page Deallocation Table (PDT) is FULL. WARNING: The system rial number is invalid. ERROR: The BMC BT interface has failed on this system, Halt Boot. WARNING: The BMC System Event Log (SEL) is full. ERROR: The BMC BT port has failed on this system and an alternate BMC port is being ud as a failover. WARNING: No graphic or rial consoles were found on this system. WARNING: No usable graphics console was found on this system. The console has defaulted to a rial port. Displaying PIM information The pin command allows you to display the most recent PIM information for the specified fault type. To display PIM information for a specific fault, execute the following from the Service Menu: pim Clearing the FPL and SEL logs The BMC clearlogs command in the Service submenu empties the log files. | NOTE: | If the SEL logs are full, a warning will be displayed when the system boots. Capture the log contents be captured and archived them before clearing the logs if the system is experiencing problems. HP support reprentatives may need the information from the files. | | | |
