> 	================================================
> 	The system provides fault LEDs in the following places:
> *	Front panel
> *	Keyboard
> *	Power supplies
> 	Error messages are logged in the /var/adm/messages file and are also
> displayed on the system console by the diagnostic tools.
> 	================================================
> 	Is this true? Will a faulty PSU will be noted in /var/adm/messages?
> 	If anyone has seen this please let me know. Or even better please
> send me a copy of the error message.
> 	Or if anyone currently has a faulty PSU ... well you could test out
> Sun's documentation if you wanted to.
> 	Please send email and I will summarise to the list.

> 	From the replies and testing so far:
> 		- "prtdiag -v" does not show PSU status
> 		- loss of power feed to PSU does not show up in
> "/var/adm/messages"
> 		- "SPANNER" LED is the only indication.

> 	Does anyone know how to detect the following scenarios via the OS:
> 		- Loss of power feed to one of the supplies
> 		- Faulty power supply
> 	Please send email and I will summarise to the list.
