4 LED Indicators and Switches This chapter provides information about locating and using system LEDs and switches in the server. For additional information about troubleshooting procedures, refer to the HP ProLiant ML370 Generation 3 Server Setup and Installation Guide. System LEDs The server contains several sets of LEDs that indicate the status and settings of hardware components.
LED Indicators and Switches Front Panel LEDs The set of five LEDs on the front of the server indicates system health. Figure 4-1 and Table 4-1 identify and describe the location and function of each LED.
LED Indicators and Switches Hot-Plug SCSI Hard Drive LEDs Each hot-plug SCSI hard drive has three LEDs located on the front of the drive. They provide activity, online, and fault status for each corresponding drive when configured as a part of an array and attached to an active Smart Array Controller. LED behaviors may vary, depending on the status of other drives in the array. Figure 4-2 and Table 4-2 and Table 4-3 identify LED locations and analyze the status of each hot-plug SCSI hard drive.
LED Indicators and Switches Table 4-3: Hot-Plug SCSI Hard Drive LED Combinations Activity LED Online LED Fault LED Status On Off Off Do not remove the drive. Removing a drive during this process causes data loss. The drive is being accessed and is not configured as part of an array. On Flashing Off Do not remove the drive. Removing a drive during this process causes data loss. The drive is rebuilding or undergoing capacity expansion. Flashing Flashing Flashing Do not remove the drive.
LED Indicators and Switches RJ-45 Connector LEDs The RJ-45 connector on the server rear panel has two LEDs. Figure 4-3 and Table 4-4 identify the LED locations and status.
LED Indicators and Switches Rear Unit Identification LED Switch The server includes unit identification (UID) LEDs with switches on both the front and rear panels. The UIDs indicate activity status and can be toggled on and off by the front or rear hardware push button or by the Insight Manager 7 application. The rear UID identifies the location of an individual server in a rack of servers. It also contains an integrated button to activate or deactivate the LED.
LED Indicators and Switches Hot-Plug Power Supply LEDs Determine the hot-plug power supply status by noting the color of the power supply LED located adjacent to the AC inlet. Figure 4-5: Hot-plug power supply LEDs Table 4-5: Hot-Plug Power Supply LEDs Item Description 1 Secondary (redundant) power supply 2 Primary power supply When the power supply LED is off, the following conditions may exist: • No AC power is available. • The power supply has failed. • The power supply is in standby mode.
LED Indicators and Switches Hot-Plug Fan LEDs Each hot-plug fan contains a dual-color LED. Figure 4-6: Hot-plug fan LED The hot-plug fan LED indicates the following conditions: 4-8 • Green = The fan is operating normally. • Amber = The fan has failed. • Off = The fan is not powered or is not seated.
LED Indicators and Switches System Board LEDs The following LEDs are located on the system board: • Processor status • PPM status • Memory status • System overtemperature • Online spare memory (OSM) status • iLO Diagnostic Figure 4-7: System board LEDs Table 4-6: System Board LEDs Item Description Status 1 Memory status 1A 2 Memory status 2A 3 Memory status 3B Amber = Memory failed 4 Memory status 4B Off = Normal 5 Memory status 5C 6 Memory status 6C continued HP ProLiant ML370

LED Indicators and Switches External Health LED Table 4-7: External Health LED System LED and Color External Health LED Color Status Power supply (off) Red Primary power supply or both power supplies have failed. Amber Secondary power supply has failed.
LED Indicators and Switches System LEDs and Internal Health LED Status Combinations When the internal health LED on the front panel illuminates either amber or red, the server is experiencing a health event. The combinations of illuminated system LEDs and the internal health LED in Table 4-8 indicate system status. NOTE: The system management driver must be installed in order for the internal health LED to provide pre-failure and system conditions.
LED Indicators and Switches Table 4-8: System LEDs and Internal Health LED Status Combinations continued System LED and Color Internal Health LED Color Status System overtemperature (amber) Red System has exceeded operating system cautionary level or critical hardware level. Green Normal. Red A required fan has failed. Amber A redundant fan has failed.
LED Indicators and Switches System Board Switches Some server operations, including adding or removing a component, changing a security feature, or reconfiguring the server from tower to rack, require that you reconfigure a system switch. If the system configuration is incorrect, the computer may not work properly and you may receive error messages on the screen.
LED Indicators and Switches Non-Maskable Interrupt Switch Crash dump analysis is an essential part of eliminating reliability problems such as hangs or crashes in operating systems, device drivers, and applications. Many crashes freeze a system, requiring you to do a hard reset. Resetting the system erases any information that supports root cause analysis. Systems running the Microsoft Windows NT operating system experience a blue screen trap when the operating system crashes.
LED Indicators and Switches System Identification Switch The system identification switch (SW2) is a three-position switch that identifies the operational configuration of the server. This switch is set to the correct configuration for the server by default. Table 4-10 shows the switch settings and positions. CAUTION: Do not alter the default setting for the server. Doing so causes improper server operation. Table 4-10: System Identification Switch (SW2) Position 4-16 Description Settings for 2.
LED Indicators and Switches System Maintenance Switch The system maintenance switch (SW1) is a six-position switch that is used for system configuration. The default setting for all six positions is off. For the proper system maintenance switch settings, refer to the labels attached to the inside of the server access panel or refer to Table 4-11. Table 4-11: System Maintenance Switch (SW1) Position Description On/Off Function 1 iLO Security enable indicator Off = iLO security enabled.
LED Indicators and Switches System Configuration Settings It may be necessary at some time to clear and reset system configuration settings. When the system maintenance switch position 6 is set to the on position, the system is prepared to erase all system configuration settings from both CMOS and NVRAM. For additional information about locating the switch and switch settings, refer to “System Maintenance Switch” in this chapter. The default setting for all positions is off.
LED Indicators and Switches ROMPaq Disaster Recovery Mode A corrupted system ROM requires that you recreate the ROM BIOS by flashing the ROM. This operation can be accomplished only when the system is in disaster recovery (emergency repair boot) mode. If both sides of the redundant ROM are corrupted, the system automatically enters the disaster recovery mode and the server emits three extended beeps. To perform ROMPaq disaster recovery: 1.
