• Was the power of the extension unit turned on before turning

 

on the power of the recorder? Reboot the system and turn on

the power of the extension unit first.

 

 

 

 

 

• When using a circuit breaker or equivalent device to turn on/off

 

the power of the whole system at once, make sure that all

devices are connected to the same power source.

 

 

 

 

 

• When using an UPS (uninterruptible power supply), connect all

devices to the same UPS.

 

 

 

 

 

• Make sure that the HDD unit is inserted all the way into the

52

HDD slot.

 

 

 

 

 

• The hard disk drive is faulty.

 

 

 

 

• Add the HDD unit to the system again.

• Make sure that the HDD units are installed in order from HDD1

 

to HDD4.

Install the HDD units one by one in order starting from HDD1.

 

 

 

The respective hard disk drive is faulty in the RAID 5 or RAID 6 mode.

In the RAID5 mode, the indicator respective to the HDD that

failed first will light red and the indicators for the other failed

126

HDD will blink red. In the RAID 6 mode, the HDD access indi-

 

cators corresponding to the first and second faulty disks will

 

light and blinks for the third and subsequent faulty disks.

 

 

 

 

 

• Make sure that the HDD unit is inserted all the way into the

52

HDD slot.

 

 

 

 

 

• The hard disk drive on which there is data to be recovered is

faulty.

 

 

 

Check if the capacity of the new hard disk drive is smaller than the original one's.

If different models are used together even when the capacities

of them are the same, the available capacity may be a few per-

128

cent smaller. When using multiple hard disk drives, use the

 

same model. Replacing to a hard disk drive whose capacity is

 

larger than the original one's is also available.

 

Make sure that recovery of data in the RAID 5/RAID 6 mode is not being processed.
