Figure 24 Installing a surge protector
(1) Grounding cable (2) Surge protector
The performance of the surge protector might be affected in the following cases:
• The surge protector is installed in reverse direction. Connect the IN end to the outdoor network
cable and the OUT end to the network port on the router.
• The surge protector is not well grounded. After the connection, use the multimeter to confirm that the
ground wire for the protector is as short as possible to ensure its good contact with the grounding
screw of the router.
• The installed surge protectors are not sufficient. If the router has more than one cable connected with
other devices through cables outdoor, install a surge protector for each cable.

the AC power source.
3. Use cable ties to secure the power cord to the rack post.
