Installing An Ethernet Port Arrester - Ruijie RG-S6920-4C Hardware Installation And Reference Manual

Hardware Installation and Reference Guide
Note
The power arrester does not come with the equipment. Please purchase it based on actual
requirements.
Important points:

Make sure that the PE terminal of the power arrester is well grounded.

After the AC power plug of the switch is connected to the socket of the power arrester
(surge protector power strip), the surge protection function is implemented only if the LED
indicating operation status is green and the LED indicating alarm status is OFF.

If the LED on the power arrester turns red, check whether it is caused by poor grounding
connection or by the reversed connection of the null and live lines. The detection method is
as follows: Use a multimeter to measure the polarity of the power socket for the arrester
when the LED turns red. If the null line is on the left and the live line is on the right (facing
the socket), the arrester's PE terminal is not grounded. If not, the null and live lines are
reversed. In this case, you should open the power arrester and reverse the null and live
lines. If the LED is still red, the arrester's PE terminal is not grounded.

Installing an Ethernet Port Arrester

Please 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
Procedure:
(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.
(2) According to the distance between the switch grounding terminal and the Ethernet port
arrester, trim the grounding wire for the Ethernet port arrester and firmly crimp the grounding
wire to the grounding lug of the switch.
(3) Use a multimeter to check whether the grounding wire 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 bundle the power cords.
