When using the power SPD, ensure the PE terminal is grounded.
Insert the AC power plug of the router into the socket of the power SPD (surge protection
connector bar). When only the green indicator indicating the running power SPD is always
on without red indicator alarms, the SPD function works.
If the red alarms happen to the power SPD, check and ensure whether the live wire,
naught wire, and PE are connected correctly. If the PE is connected correctly, perform
further detection. Switching the multimeter to the AC power, test whether the voltage
between the naught wire and the PE is less than 5 V and whether the voltage between the
live wire and the PE is about 220 V. If no, it indicates that the live wire and the naught
wire are reversely connected.
3.3.2 Install Port Lightning Protector
When using the device, if an outdoor network cable will be connected to the device, first
cascade the port lightning protector before connecting the network cable to the device
interface, so as to reduce the probability of device damage caused by lightning stroke.
The port lightning protector is installed as follows:
Step 1:
Cut short the PE of the port lightning protector based on the distance of the
device ground terminal or the lightning protection ground copper bar in the
equipment room. Tighten the PE of the port lightning protector securely to the
device ground terminal or the lightning protection ground copper bar in the
equipment room.
Step 2:
Use a multimeter to test whether the lightning protector PE is well connected to
the device ground terminal or the lightning protection ground copper bar in the
equipment room.
Step 3:
According to the description on the port lightning protector specification, use the
network port conversion cable to connect the port lightning protector (Pay
attention to the connection direction and note that the external cable is
connected to the IN end and the conversion cable on the router is connected to
the OUT end). At the same time, observe whether the indicators on the boards
are normal.
Step 4:
Bind the cables tidily using cable ties.
The port lightning protector is not provided with the router. The user can purchase it as
required.
The port lightning protector aims for the Ethernet port of the 10/100/1000M electrical
interface using the RJ-45 connector.
The port lightning protector specifications contain the technical parameters and the
installation and maintenance instruction of the surge protector. Refer to the specifications
carefully in the actual installation.
