2-2-2. Adding a Hard Drive
Up to four hard drive s may be installed in the system using two hard drive cables.
Each hard drive cable can connect two hard drive s, which must be configured in master-slave
structure.
In the absence of CD-RW, two hard drive bays are installed: one on the right and the other on the
left. If there is a CD-RW, however, only two hard drive bays are installed on the right.
The jumper setting method varies by manufacturer or model. Refer to the jumper setting
information marked on the front side of the hard drive .
Example - Setting the jumpers for the western digital WD1200 hard drive
Adding a Hard Drive
1) Before installing the HDD, turn off the DVR and disconnect the power cord.
2) Never touch grounded metallic objects when installing the HDD (may cause the body to
absorb static electricity, which in turn can cause problems in the DVR).
3) After installing the HDD, do not turn the power ON until the top cover is closed. Never use the
DVR with the top cover opened.

Before turning OFF the power, shut down the system first.
Unscrew and open the upper case.
Unscrew the hard drive bay using a
screwdriver and separate the hard
drive bay from the body.
Insert the hard drives into the hard drive bay
