HOW TO CHANGE FROM RAID 5 TO RAID 5+1
To change a RAID 5 configuration to a RAID 5+1 configuration, you must add a hot spare hard drive. A hot spare hard drive
becomes the replacement hard drive when a hard drive fails in the RAID 5+1 configuration. Make sure you have the appropri-
ate spare drive from Pelco: DX9000DRV-I120 or DX9000DRV-I250.
Because the hard drives are hot-swappable, you do not have to shut down the power before adding or removing them.
WARNING: Handle the hard drive with extreme care. Do not drop or jar the hard drive as delicate components inside may be
damaged. Observe electrostatic discharge (ESD) precautions: Use a grounded wrist strap when handling the hard drive. Avoid
touching electronic components.
1. Lower the panel on the front of the storage unit.
2. Locate an empty hard drive tray. Refer to the LCD display to see which slot is empty.
3. Push down the lever release.
4. Pull out the empty hard drive tray.
5. Set the jumper on the hard drive to “Master.”
6. Connect the power connector to the power port on the hard drive.
7. Connect the 40-pin 80-conduction ATA cable connector to the ATA cable connector port on the hard drive.
8. Place the hard drive in the tray and secure it using the four Phillips screws.
9. Slide the tray into the empty slot until it clicks into place.
10. Push the lever down until you hear it click into place.
11. Raise the panel.
An “S” appears on the LCD display indicating the slot with the hot spare hard drive.
HOW TO REPLACE A FAILED HARD DRIVE
The DX9000 continues to operate properly if one hard drive fails. If two hard drives fail, however, the system does not operate
properly. Make sure a failed hard drive is replaced immediately.
WARNING: Handle the hard drive with extreme care. Do not drop or jar the hard drive as delicate components inside may be
damaged. Observe electrostatic discharge (ESD) precautions: Use a grounded wrist strap when handling the hard drive. Avoid
touching electronic components.
In a RAID 5 configuration, when you replace a failed hard drive, the new hard drive rebuilds automatically. In a RAID 5+1
configuration, when you replace a failed hard drive, the new hard drive becomes the hot spare. Make sure you have the
appropriate hard drive from Pelco: DX9000DRV-I120 or DX9000DRV-I250.
1. Lower the panel on the front of the storage unit.
2. Push down the lever release.
3. Remove the tray that has the failed hard drive. The LED of the failed hard drive should be red.
4. Remove the defective hard drive from the tray by unscrewing the four Phillips screws.
5. Set the jumper on the replacement hard drive to “Master.”
6. Connect the power connector to the power port on the hard drive.
7. Connect the 40-pin 80-conduction ATA cable connector to the ATA cable connector port on the hard drive.
8. Place the hard drive in the tray and secure it using the four Phillips screws.
9. Slide the tray into the empty slot where the defective hard drive was until it clicks into place.
10. Push the lever down until you hear it click into place.
11. Raise the panel.
Make sure the hard drives are installed in the correct slots. If the hard drives are installed in the wrong slots, the DX9000
system will not operate properly.
