Cisco Cisco 1900 2900 3900 Series 8-Port Gigabit Ethernet HS-WIC with PoE Guide De Montage

Tighten threaded contacts to the torque specified by the manufacturer.

This arrestor is designed to be installed in series between the antenna cable that is attached to the 3G 
outdoor antenna and the second antenna cable entering the building. It is recommended that the arrestor 
and its ground connection is made as close as possible to where it enters the building, either just outside 
or just inside the building.

Cisco recommends that the lightning arrestor be bulkhead-mounted and grounded (i.e., arrestor attached 
directly onto a well-grounded bracket or well-grounded panel via the arrestor's threaded shaft and the 
supplied nut).  If this is not possible, then the next best option is to use the ground lug provided with the 
kit. The ground lug requires a 6 AWG copper ground wire (user provided) to be crimped onto the lug, 
with the other end of the ground wire connected to a good solid ground point (eg, to an electrical ground 
buss bar), keeping the ground wire length as short as possible for best results (under 20 inches or under 
0.5 meters). See
