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. The rx2660 server 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 turns green soon as the system starts to power up.
2.
The external health indicator turns green as soon as the BMC can light it.
3.
The internal health indicator turns 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).
4.
The system health indicator turns green when firmware leaves “exit boot services” and
begins to boot an OS.
