Power strip with lightning protection
If part of the AC power line is routed outdoors, use a power strip with lightning protection to connect the
AC power cord of the router to the AC power line to protect the router from being damaged by lightning
strikes.
The specifications for the power strip with lightning protection that can be installed on the router are as
follows:
Maximum discharge current: 6500 A, protection voltage: 500 VAC to 220 VAC.
For how to install the power lightning protector, see "

with lightning protection ."
Surge lightning protector
Generally, you need to connect a surge protector before connecting a signal cable to the router. This can
protect electronic devices against surge over-voltage resulting from lightning strokes and other
interferences, and minimize impact on the router.
The router supports the following types of surge protectors:
• Surge protector—Maximum discharge current 2.5 KA/protection voltage 25V--SMB-75J/
SMB-75J-1W-10Mbps
• Surge protector—Maximum discharge current 2.5 KA/protection voltage 25V-BNC-75K/
BNC-75K-10Mbps
• Surge protector (U port)—Maximum discharge current 3 KA/common-mode 400V/differential
mode 170V-RJ11
