LEDs

Front Panel
The front panel of the system contains the Power Button/System Power LED, Internal and External Health
LEDs, System Health LED, Locator Switch/LED, and an INIT button. rx6600 servers use flashing states (for
example, flashing amber or red) on these LEDs to indicate a warning or an error.
There are a total of three buttons, arranged horizontally, with the UID button and the power button each
having an integrated LED. In addition to the two integrated button/LEDs, there are three health LEDs and
an INIT button.
The health LEDs are arranged sequentially in line with the Power button/LED, and as the system starts up,
there will be more "green" the further the system proceeds in the startup process.
1. The power LED will turn green soon as the system starts to power up.
2. The external health indicator will turn green as soon as the BMC can light it.
3. The internal health indicator will turn green as soon as the BOOT_START event is received from system
firmware (BOOT_START can be determined by LED states on the I/O backplane board).
4. The system health indicator will turn green when firmware leaves "exit boot services" and we begin to
boot an OS.
The health LEDs are driven by the BMC; the Power LED is driven solely by hardware. BMC code determines
the state of the Internal and External Health LEDs, while the iLO 2 MP code, examining incoming events
using its event dictionary, determines the state of the System Health LED.
External Health LED (EHLED)
The front panel Externally Serviceable Server Health LED, called the External Health LED, indicates the
status of the components that are externally serviceable. In most systems, this LED is only used to monitor
the power supply status and external fans (rx6600 only). Whenever the external health LED is lit, the
corresponding FRU should be lit for the failed component.
Failures that cause the External Health LED to light will not cause the Internal Health LED to light. These
two LEDs cover failures of different components.
Table 5-4 displays information about the External Health LED states.
Table 5-4 External Health LED States
Health good on all external FRUs and system power is off.
System power is on; externally serviceable components (usually
accessible from front or back, such as fans and power supplies)
are okay.
An externally accessible FRU failed (system is on or in standby
mode). Usually, this is a power supply or fan failure. Check
front/back LEDs for failed component.
