Cable for the Lightning Arrestor
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.
Grounding the Access Point
The access point must be grounded before connecting power.
Warning
This equipment must be externally grounded using a customer-supplied ground wire before power is
applied. Contact the appropriate electrical inspection authority or an electrician if you are uncertain
that suitable grounding is available.
