The Meaning of the LEDs |
This appendix describes the LEDs on the front and back of the Sun Fire B1600 blade system chassis and tells you the meanings of their different states. It contains the following section:
Use the LEDs on the individual system components to determine if the system is operating normally. We recommend you monitor the LEDs routinely on the SSCs, Power Supply Units, and server blades
The LEDs can be off, on, or in some cases blinking slowly or flashing. When the Service Required LED is on (lit), this indicates that a fault has occurred in the component. A fault is any condition that is considered to be unacceptable for normal operation. When the Service Required LED is lit, you must take immediate action to clear the fault.
You can only remove a hot-swappable component when the blue Ready to Remove LED is lit.
If all LEDs are off on the chassis, check your external power source. If the LEDs are all off on a particular component, issue the poweron command to that component.
Service is required to the component and the component is ready to remove.
This combination is most likely to be seen on a PSU. It indicates that the PSU is providing power to the chassis (note that a PSU cannot be powered off) but that it has been prepared for removal.
Remove the PSU and insert the replacement PSU within 10 minutes (see the Caution box below).

Issue the poweroff -r or the removefru command to the faulty component. Then remove the component.
No action required, but type poweron sn (where n is the number of a blade) when you want to power on the blade. If the blade is at the ok prompt, type boot to load the operating system. If it is not at the ok prompt, wait until it is. If it does not return to the ok prompt or the Solaris prompt, reset the blade from the sc> prompt.
Blade is self-testing, initalising, or booting. It is powered on, but the Operating System is not running.
