19• In the RAID 6 modeOne of the "1DOWN", "2DOWN" and "3DOWN" indica-tions (corresponding to the failure) will be displayed and willstart blinking.The respective HDD access indicator(s) will also light orblink red. (Page 30)Important:• In the RAID 6 mode, it is possible to read data on the otherhard disk drives and recover data even when 2 hard diskdrives become faulty (2DOWN).When a hard disk drive failure (1DOWN, 2DOWN) occurs,replace the faulty disk(s) immediately and recover data.If 3 or more hard disk drives become faulty (3DOWN) orwhen another hard disk drive becomes faulty during thedata recovery, it is impossible to recover data.During data recovery• In the RAID 5 modeThe following indication will be displayed.During preparation of data recoveryDuring process of data recovery (writing data)When the data recovery starts, the respective HDD accessindicator will light orange and red alternately. (Page 31)• In the RAID 6 modeThe same indication will be displayed as above even in theRAID 6 mode during data recovery.Operations using the buttons on the front panel■ Operational mode display(standby display)The current operational mode and the internal temperature willbe displayed on the LCD.Refer to the manuals provided with the recorder for informationon how to display the disk configuration menu from the setupmenu and format the hard disk drives, etc.● When the operational mode is"SINGLE"(Temperature will be displayed in Fahrenheit for NTSC model,e.g. "90 °F")● When the operational mode is"RAID5" or "RAID6"Standby displayAt a hard disk drive failure• In the RAID 5 modeThe "1DOWN" or "2DOWN" indication (corresponding tothe failure) will be displayed and will start blinking.The respective HDD access indicator(s) will also light orblink red. (Page 30)Important:• In the RAID 5 mode, it is possible to read data on the otherhard disk drives and recover data even when a single harddisk drive becomes faulty (1DOWN).When a hard disk drive becomes faulty (1DOWN), replaceit immediately.If 2 or more hard disk drives become faulty (2DOWN) orwhen another hard disk drive becomes faulty during thedata recovery, it is impossible to recover data.
