Installing the Ethernet Port Arrester 
Connect  an  Ethernet port  arrester  to the  switch  to  prevent  the  damage  by  lightning  before  connecting  an 
outdoor network cable to the switch. 
Tools: Phillips screwdrivers or flat-head screwdriver, multimeter, and diagonal pliers 
Installation Steps: 
(1)  Tear one side of the protective paper for the double-sided adhesive tape and paste the tape to the enclosure 
of the Ethernet port arrester. Tear the other side of the protective paper for the double-sided adhesive tape 
and paste the Ethernet port arrester to the switch enclosure. The paste position for the Ethernet port arrester 
should be as close to the grounding terminal of the switch as possible. over any of its shares arising under 
its Articles of Association; 
(2)  According to the distance between the switch grounding terminal and the Ethernet port arrester, cut the 
grounding cable for the Ethernet port arrester and firmly crimp the grounding cable to the grounding terminal 
of the switch. 
(3)  Use a multimeter to check whether the grounding cable for the arrester is in good contact with the grounding 
terminal and the enclosure of the switch. 
(4)  Connect the arrester by using an adapter cable (note that the external network cable is connected to the IN 
end, while the adapter cable connected to the switch is connected to the OUT end) and check whether the 
service module LED is normal. 
(5)  Use a nylon cable tie to bind the power cords.
