Troubleshooting

Check the System Status LED
The system status LED reports the condition of the enclosure fan and power supply:
Solid Blue: NVR is functioning normally
Blinking Blue: NVR is shutting down
If your unit is configured to work with a UPS, it will continue to run for a while after a power supply failure.
Check Disk Status LEDs
The disk status LEDs report the condition of the disk drives:
These lights will be solid BLUE when drives are connected but inactive.
The lights will blink when the drives are being accessed, formatted, or synchronized.
They will illuminate AMBER if a drive has failed.
Replace a Failed Disk Drive
If a disk drive fails, the Disk Status LED will turn amber. If the disk drive belongs to a RAID Volume, the Volume will go Critical
or Offline.
Replace the failed disk drive with a new disk drive of the same or slightly greater capacity.
Please make sure you have powered down the unit, then take the following steps:
Step 1: Open the unit's front cover.
Step 2: Pull out the failed disk drive.
Step 3: Install a new disk drive into the slot.
If the failed drive belonged to a RAID Volume, the RAID Volume will begin rebuilding as soon as the new drive is installed.
During the rebuild, the Disk Status LED will blink. If the replacement drive is free, i.e. not assigned to a RAID Volume or as a
spare, the Disk Status LED remains dark after you install the new drive.
Check RAID Volume Status
Click the Status -> Device Info tab from the menu.
