Introduction
This manual provides instructions for replacing the primary master hard drive in a DX7100 Series DVR (digital video
recorder).
PARTS LIST
NOTE: This replacement kit includes a Pelco-certified hard disk drive. Using any other hard disk drive with the DX7100
voids the manufacturer's warranty for the DX7100.
1 120 GB hard disk drive
2 Mounting screws
1 DX7100-RPS software recovery CD
Normally, after replacing the hard disk drive, your system should operate properly. However, it if does not, the DX7100-RPS
software recovery CD is provided to restore your DVR to proper operation. Follow the instructions provided on the CD.
TOOLS NEEDED
1 Phillips screwdriver
1 Properly grounded ESD wrist strap and mat
1 Small container to store screws (optional)
C674M (2/06) 3

Installation
WARNING: Any video on the primary master hard drive will be lost when the drive is replaced.
To replace the primary master hard drive:
1. To protect the DVR and its components against electrostatic discharge, make sure that you are properly grounded so
that any built-up static electric charges are dissipated away from the unit. The most effective way to do this is to use
a properly grounded wrist strap. If a wrist strap is not available, you can discharge built-up static by periodically
touching an unpainted section of the chassis.
2. Turn off power.
3. Remove the top cover of the DVR (refer to Figure 1). Remove two screws on each side and three on the back of the
DVR. Loosen the top screw on each rack ear to make removal of the lid easier. Slide the top cover back and lift it up.
