Figure 23 Install a port lightning arrester
Precautions
The performance of the signal lightning arrester may be affected in the following cases:
•
The IN and OUT ends of the signal lightning arrester are connected incorrectly.
The IN end should be connected to the external cable, and the OUT end to the Ethernet port of the
router.
•
The signal lightning arrester is not well grounded. Make sure that the grounding cable of the signal
lightning arrester should be as short as possible and be well connected to the grounding screw of
the router. Use a multimeter to check the connection between the signal lightening arrester and the
grounding screw.
The installed signal lightning arresters are not sufficient. When more than one outdoor Ethernet cable is
connected to the router, install a signal lightning arrester for each outdoor Ethernet cable.
