Warning
1. The power arrester is not provided, the user shall purchase it to address
the pratical requirement;
2. Make sure that the PE terminal of the power arrester has been
well-grounded;
3. After connecting the switch AC power plug to the socket of the power
arrester(lightning protection cable row), lightning protection function
implements if the RUN LED is Green and the ALARM LED is OFF.
4. If the ALARM LED on the power arrester is Red, you shall check what the
reason is, poor grounding connection or the reversed connection of the Null
and Live lines: Use the multimeter to check the polarity of the power socket
for the arrester when the LED is Red, if the N line is on the left and the L line is
on the right, the arrester PE terminal is not grounded; if the L line is on the left
and the N line is on the right, the polarity of the arrester power cable shall be
reversed; if the LED is still Red, it is confirmed that the arrester PE terminal
has not been grounded.
2. Installing the Ethernet Port Arrester
During the switch usage, the Ethernet port arrester shall be connected to the switch to
prevent the switch damage by lightning before the outdoor network cable connects to the
switch.
2.1 Tools
Cross or straight screwdriver
Multimeter
Inclined pliers
2.2 Installation Steps
Step 1: Tear one side of the protection paper for the double-sided adhesive tape and paste
the tape to the framework of the Ethernet port arrester. Tear the other side of the protection
paper for the double-sided adhesive tape and paste the Ethernet port arrester to the switch
framework. The paste location for the Ethernet port arrester shall be as close to the
grounding terminal of the switch.
Step2: Based on the distance of the switch grounding terminal, cut the grounding line for the
Ethernet port arrester and firmly tighten the grounding line to the grounding terminal of the
switch.
Step 3: Use the multimeter to check whether the grounding line for the arrester is in good
contact with the switch grounding terminal and the framework.
Step 4: According to the description on the Ethernet Port Arrester Hardware Installation
Guide, connect the arrester using the adapter cable(note that the network cable is
