Руководство По Установке для Cisco Cisco 1900 2900 3900 Series 8-Port Gigabit Ethernet HS-WIC with PoE

This lightning arrestor is part of a lightning arrestor kit. The kit contains a lightning arrestor, a grounding 
lug, and this instruction sheet.

When you install the lightning arrestor, follow the regulations or best practices applicable to lightning 
protection installation in your local area.

Coaxial cable loses efficiency as the frequency increases, resulting in signal loss. The cable should be 
kept as short as possible because cable length also determines the amount of signal loss (the longer the 
run, the greater the loss).

Cisco recommends a high-quality, low-loss cable for use with the lightning arrestor.
