 The power SPD is not provided with the router. The user can purchase it as
required.
 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 occur 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 220V. If no, it indicates that the live wire and the naught
wire are reversely connected.
2.3.3. (Optional) Install Port Lightning Protector
When using the router, if an outdoor network cable will be connected to the router, first
cascade the port lightning protector before connecting the signal line to the router interface to
reduce the probability of router 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
router ground terminal or the lightning protection ground copper bar in the
equipment room. Tighten the PE of the port lightning protector securely to the
router 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 router 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.
