Adding the Hard Drive

To install the hard drive:

  1. Confirm that the DVR is completely powered off. There should be no LED lights ignited on the front panel of the DVR. If there is still power, soft-shutdown or disconnect the power cable from the DVR.

**NOTE: For a soft shutdown, press the power button on the front of the unit, then select Shutdown. Alternatively, if you are currently logged in at the DVR, click on the power icon on the toolbar at the bottom of the screen while in Live View, then select Shutdown.

 

  1. Remove the four screws from the back panel of the DVR, then remove the top cover of the unit.

 

  1. Attach the power supply cable and SATA cable to the new hard drive.

 

  1. Carefully place a hand on the hard drive, hold it in place, and turn the DVR over. Insert four mounting screws to secure the hard drive to the inside of the DVR.
  1. Replace the top cover of the unit. Replace the four screws at the back panel of the DVR to secure the top cover.
  2. Connect the DVR’s power cable and power the unit on.
  3. Log in as the Administrator, right-click with your mouse, and select Menu to open the system’s Setup Menu.
  4. Navigate the menu to the Hard Drive menu (Site > HDD). The Hard Drive menu should display your new hard drive’s model, capacity, and free space. Prior to use, it is recommended to format the hard drive.

  5.  To format the hard drive, check the box next to the HDD name then click the Format button.

    A confirmation message will appear, asking you to confirm if you wish to proceed. Confirm the message and allow the DVR to format your new hard drive. The progress bar at the bottom of the menu shows you the status of the format.

 

  1. Once the hard drive is done formatting, a confirmation message will appear. Confirm the message and reboot the DVR. Once the DVR is done rebooting, you may use your recorder normally.

**NOTE: If the DVR experiences recording issues or does not detect the new hard drive, power the unit off and confirm that the power supply cable and SATA cable are securely connected to the hard drive.
