APPENDIX C: HDD INSTALLATION
APPENDIXC HDD Installation
The following procedures illustrate hard disk drive (HDD) installation in a ALI-NVR3000P series NVR without an HDD, and
installation of a second HDD. If you purchased your NVR without a HDD, or you want to replace the HDD installed in your NVR, use
this procedure as a guideline.
C.1 NVR compatible HDDs
For the best performance of your system, install only a high-reliability security grade HDD. Security grade HDDs are designed to
stream video eciently.
C.2 Initial HDD Installation
The NVR will accommodate one or two internal HDDs. The HDD attaches to the chassis with four screws inserted up through the
underside of the chassis. The HDD mounting screws and HDD cables are provided with your HDD.
CAUTION

Follow recommended electrostatic discharge (ESD) guidelines while performing this procedure. Install the HDD in a static-free
environment, wearing a certied ESD wrist strap. If a static free environment and ESD wrist strap is not available, touch the bare
metal of the DVR chassis frequently when installing the drive to dissipate the static charge naturally generated on your skin and
clothing and avoid touching electronic components.
1. Power o the NVR, if necessary, then disconnect the power cord from the back of the NVR.
2. Remove the top cover from the NVR by removing the two cover screws on the back of the chassis, and the three on each side.
