Troubleshooting the Front Panel Indicators
The eight indicators on the server front panel show the state of the server. For more information about the front panel indicator locations, see Server Front Panel Features.
The following sections describe the conditions of the front panel indicators for various server states:
Server Boot Process and Normal Operating State Indicators
A normal server boot process involves two indicators, the service processor (SP) indicator and the system OK indicator. The process is described below:
-
When the AC power is applied to the server, the service processor (SP) boots. While the SP boots its indicator blinks at the slow blink rate (for indicator blink rate information, see Indicator Blink Rates), and the system OK indicator is off steady.
-
When the SP has successfully booted, the SP indicator is on steady, and the system OK indicator blinks at the single blink rate. When the SP indicator is on steady and the system OK indicator is at the single blink rate, the server is in standby power mode (see Standby Power Mode).
-
When the server is booting (powered on), the system OK indicator blinks at the fast blink rate, and the SP indicator is on steady. When the server has successfully booted, the system OK indicator turns on steady. When the system OK indicator and the SP indicator are on steady, the server is in full power mode (see Full Power Mode).
-
For a server in a normal operating state, the green system OK indicator and the green SP indicator are on steady (no blink).
Locator Indicator On
When the Locator indicator is activated from Oracle ILOM or from the front panel (by pressing the Locate button), the indicator blinks at the fast blink rate. The indicator assists in finding a server within a rack of servers (for example, when activated remotely to correctly identify a server requiring service).
For indicator blink rate information, see Indicator Blink Rates.
Over Temperature Condition
For a server in an over-temperature state, the amber Service Action Required and Temperature indicators are on steady. The green system OK indicator and the green SP indicator are on steady.
For indicator blink rate information, see Indicator Blink Rates.
PSU Failure
For a server with one of its PSU's in a failed state, the amber Service Action Required and PS REAR indicators are on steady. The green system OK indicator and the green SP indicator are on steady.
For indicator blink rate information, see Indicator Blink Rates.
Memory Failure
For a server with a failure in the memory subsystem, the amber Service Action Required and MEM TOP indicators are on steady. The green system OK indicator and the green SP indicator are on steady.
For indicator blink rate information, see Indicator Blink Rates.
CPU Failure
For a server with a fault in the processor subsystem, the amber Service Action Required and CPU TOP indicators are on steady. The activity of green system OK indicator and the green SP indicator vary depending on whether the server can boot successfully. The server might not be able to boot out of standby power mode.
For indicator blink rate information, see Indicator Blink Rates.
Fan Module Failure
For a server with a fan module fault, the amber Service Action Required and the FAN TOP indicators are on steady. The green system OK indicator and the green SP indicator are on steady.
For indicator blink rate information, see Indicator Blink Rates.
SP Failure
For a server with an SP fault, the amber Service Action Required indicator is on steady. The green system OK indicator and the green SP indicator are off.
For indicator blink rate information, see Indicator Blink Rates.
Front Panel Lamp Test
To perform a lamp test of all front panel indicators, press the Locate button three times within a five second period. All the indicators light up and remain on steady for 15 seconds (see Unison Steady On).
For indicator blink rate information, see Indicator Blink Rates.
