4.6.3 Precautions
Pay attention that the performance of the port lightning arrester may be affected in the
following cases:
z
The IN and OUT ends of the port lightning arrester are connected incorrectly.
The IN end should be connected to the external cable, while the OUT end should
be connected to the Ethernet port of the firewall.
z
The port lightning arrester is not well grounded.
Make sure that the grounding cable of the port lightning arrester should be as short
as possible and be well connected to the grounding screw of the firewall. You need
to check with a multimeter after connection.
z
The installed port lightning arresters are not sufficient.
When more than one outdoor Ethernet cable is connected to the firewall, you need
to install a port lightning arrester for each outdoor Ethernet cable.
4.7 Installing a Power Lightning Arrester (Lightning
Protection Busbar) (Optional)
Note:
No power lightning arrester is shipped with the firewall. You should purchase one if
needed.
Before connecting an outdoor AC power supply to the firewall, you need to install a
lightning protection busbar at the AC power input end and then connect the AC power
cord to a lightning protection busbar to protect the firewall against lightning strokes. You
can use cable ties and screws to fasten the lightning protection busbar on the cabinet,
the workbench, or the wall in the equipment room.
