18. Power States and Misoperation
The HD/HDR-FOX has several power states:
OFF: Mains power disconnected (the HDR-FOX has a mains switch on the rear panel). Obviously this is a zero-power state. Powering up from the OFF state is referred to as a "cold start", and the old chestnut "have you tried turning it off and on again" can be helpful in clearing strange faults. As with all computer equipment (the HD/HDR-FOX is essentially a special-purpose computer), it is advisable to perform a controlled shut-down (go from ON to STANDBY, and wait at least 30 seconds before going to OFF), but in this case there is only minor risk in not doing so (eg a corrupted file if the HD/HDR-FOX was in the process of writing to disk at the time).
STANDBY: This is the low-power state, where the HD/HDR-FOX is doing nothing but waiting to be turned on (via remote control or front-panel button press) or for the internal clock to trigger an event. The actual power consumed in STANDBY depends on the "Power Saving in Standby" setting, see Section 7. In STANDBY the internal disk drive is not spinning (HDR-FOX) and power to external USB devices is cut. The processor is not running and there will be no response to network activity.
COMA: This is a fault state. Internal and external drives are powered but there is no other activity or response. This has been noted to occur when:
- Power On / Power Off Timers are mismatched (ie one is set but not the other);
- There is a corrupt file or file system (the coma state vanishes when the offending file is deleted, but may not return if the "offending" file is reinstated).
HALF-AWAKE: The HD/HDR-FOX is fully functional (drives spinning, processor active and able to respond to network activity) except there is no video output and the DLNA server is not running, and there is no response to the remote control (other than the power button). The HALF-AWAKE state is the situation when the HD/HDR-FOX is recording from STANDBY (or preparing to record - using AR starts up 15 minutes before the scheduled programme time), or is turned off while it is recording, or is preparing to enter STANDBY (controlled shutdown).
ON: The HD/HDR-FOX is fully functional as per HALF-AWAKE, plus video output etc. Turning on from HALF-AWAKE is almost instant. Turning on from STANDBY requires time for the processor to boot up etc, during which the Humax splash screen appears on the video output.
