HDX and power interruptions

Posted by: sktn77a on 26 September 2011

I note that the user manual for the HDX has very specific instructions for powering-down the HDX.  Like a computer, it appears to need to do a lot of "stuff" before power is removed (eg by switching it off on the rear panel switch).  What about power service interruptions?  This is equivalent to switching it off by the rear swith without going through the normal power-down sequence.  What's the 411 on this?

 

Anybody........  Bueller.......  Anybody???

Don't worry, your HDX will do fine...

Well, either way, there's not a lot we can do about it (UPS being verboten by NAIM).  But why the scary instructions in the manual?

Generally the HDX (as with any Naim Music Server) will survive a power out intact as *MOST* of the time it isn't writing to its drives. The times when it is most active at writing data to the drives (and therefore most vulnerable) are:

 

1) When it is ripping. (Hopefully fairly obviously.)

 

2) When it is shutting down.

 

We've tried to make the servers as resilient as possible but it is always advisable to properly shut them down when necessary rather than just pulling the power.

Ah, OK.  So unless we're particularly jinxed (a power outage simulaneous with an occasional system-generated disk write) we should be OK.

 

Thanks.
