These sections describe Exadata Server X10M status indicators (LEDs) located on the front and back panels, including indicators located on components and ports.

System-Level Status Indicators

System-level status indicators (LEDs) are located on both the server front panel and the back panel. For the location of the status indicators, see Front Panel Components and Back Panel Components. The following table describes these indicators.

Table A-1 System-Level Status Indicators

Status Indicator Name	Icon	Color	State and Meaning
Locate Button/LED	Front and back panel	White	Indicates the location of the server. OFF – Server is operating normally. FAST BLINK (250 ms) – Use Oracle ILOM to activate this LED indicator to enable you to locate a particular system quickly and easily. Pressing the Locate button toggles the LED indicator fast blink on or off.
Service Fault-Service Required	Front and back panel	Amber	Indicates the fault state of the server. OFF – The server is operating normally. STEADY ON – A fault is present on the server. This LED indicator lights whenever a fault indicator lights for a replaceable component on the server. Note: When this LED indicator is lit, a system console message might appear that includes a recommended service action.
OK System OK	Front and back panel	Green	Indicates the operational state of the chassis. OFF – AC power is not present or the Oracle ILOM boot is not complete. STANDBY BLINK (on for 100 ms, off for 2900 ms) – Standby power is on, but the chassis power is off and the Oracle ILOM SP is running. SLOW BLINK (1000 ms) – Startup sequence was initiated on the host. This pattern begins soon after you power on the server. This status indicates either: power-on self-test (POST) code checkpoint tests are running on the server host system, or the host is transitioning from the powered-on state to the standby state on shutdown. STEADY ON – The server is powered on, and all host POST code checkpoint tests are complete. The server is in one of the following states: the server host is booting the operating system (OS), or the server host is running the OS.
SP OK	Front panel	Green	Indicates the state of the service processor. OFF – Service processor (SP) is not running. SLOW BLINK – SP is booting. STEADY ON – SP is fully operational.
Top Fan	Front panel	Amber	Indicates that one or more of the internal fan modules failed. OFF – Indicates steady state; no service is required. STEADY ON – Indicates service required.
Rear Power Supply Fault	Front panel	Amber	Indicates that one of the server power supplies failed. PS0 and PS1 are located on the server back panel. OFF – Indicates steady state; no service is required. STEADY ON – Indicates service required; service the power supply.
Temp-Fault System Over Temperature Warning	Front panel	Amber	Indicates a warning for an overtemperature condition. OFF – Normal operation; no service is required. STEADY ON – The system is experiencing an overtemperature warning condition. Note: This is a warning indication, not a fatal overtemperature. Failure to correct this might result in the system overheating and shutting down unexpectedly.
DO NOT SERVICE	Front panel	White	Indicates that the system is not ready to service. OFF – Normal operation. STEADY ON – The system is not ready for service. Note: The DO NOT SERVICE indicator is application specific. This indicator is only illuminated on demand by the Host application.

Motherboard Status Indicators

The motherboard contains the following status indicators (LEDs).

Table A-7 Motherboard Status Indicators

Status Indicator	Description
DIMM Fault Status Indicators	Each of the 24 DIMM slots on the motherboard has an amber fault status indicator (LED) associated with it. If Oracle ILOM determines that a DIMM is faulty, pressing the Fault Remind button on the motherboard I/O card signals the service processor to light the fault LED associated with the failed DIMM. See Servicing DIMMs.
Processor Fault Status Indicators	The motherboard includes a fault status indicator (LED) adjacent to each of the two processor sockets. These LEDs indicate when a processor fails. Pressing the Fault Remind button on the motherboard I/O card signals the service processor to light the fault status indicators associated with the failed processors. See Servicing Processors.
Fault Remind Status Indicator	This status indicator (LED) is located next to the Fault Remind button and is powered from the super capacitor that powers the fault LEDs on the motherboard. This LED lights to indicate that the fault remind circuitry is working properly in cases where no components failed and, as a result, none of the component fault LEDs illuminate. See Using the Server Fault Remind Button.
STBY PWRGD Status Indicator	This green status indicator (LED) is labeled STBY PWRGD and is located on the motherboard near the back of the server. STBY PWRGD LED lights to inform a service technician that the motherboard is receiving Standby power from at least one of the power supplies. This LED helps prevent service actions on the server internal components while the AC power cords are installed and power is being supplied to the server.

Boot Process and Normal Operating State Indicators

A normal server boot process involves two indicators, the service processor SP OK LED indicator and the System OK LED indicator.

When AC power is connected to the server, the server boots into standby power mode:

1. The SP OK LED blinks slowly (0.5 seconds on, 0.5 seconds off) while the SP is starting, and the System OK LED remains off until the SP is ready.

2. After a few minutes, the main System OK LED slowly flashes the standby blink pattern (0.1 seconds on, 2.9 seconds off), indicating that the SP (and Oracle ILOM) is ready for use. In Standby power mode, the server is not initialized or fully powered on at this point.

When powering on the server (either by the On/Standby button or Oracle ILOM), the server boots to full power mode:

1. The System OK LED blinks slowly (0.5 seconds on, 0.5 seconds off), and the SP OK LED remains lit (no blinking).

2. When the server successfully boots, the System OK LED remains lit. When the System OK LED and the SP OK LED indicators remain lit, the server is in Main power mode.

Note:

The green System OK LED indicator and the green SP OK indicator remain lit (no blinking) when the server is in a normal operating state.
