Chapter 1 Introducing the ZyWALL
Screw the two screws provided with your ZyWALL into the wall 150 mm apart (see
1
the figure in step 2). Use screws with 6 mm ~ 8 mm (0.24" ~ 0.31") wide heads.
Do not screw the screws all the way in to the wall; leave a small gap between the
head of the screw and the wall.
The gap must be big enough for the screw heads to slide into the screw slots and
the connection cables to run down the back of the ZyWALL.
Note: Make sure the screws are securely fixed to the wall and strong enough to hold
the weight of the ZyWALL with the connection cables.
Align the holes on the back of the ZyWALL with the screws on the wall. Hang

the ZyWALL on the screws.
