Cisco Cisco 1900 2900 3900 Series 4-Port Gigabit Ethernet HS-WIC with PoE 安装指南

This antenna used with this product is intended for “short run” installations (that is, less than 15 feet 
from antenna to router). It is not recommended that the antenna cable length extend beyond 15 feet since 
router performance will be degraded.

The following sections contain procedures for installing the antenna on a wall:

Drill where appropriate on a flat surface of the machine to mount the antenna (mounting wall thickness 
from 0.1"-0.5" OR 2.54mm - 12.7mm) a round hole (0.812 " diameter using a drill bit 13/16" OR using 
a drill bit of 20.5mm ) for the antenna stem and a round hole of 0.234" diameter using the 15/64" drill 
bit [or using the drill bit of 6mm]  for the locking screw at a distance.

Insert the antenna with the adhered gasket, which has a chamfered threaded ¾"-24 UNS diameter stem, 
through the 0.812" diameter round hole on the mounting surface.

Install the plate support with a chamfered hole for the antenna stem and a M5 tapped hole as shown in 
the assembly picture on page 2

Install the ¾" locking washer

Install the ¾"-24 UNS nut to hold the antenna but not tighten it yet.

Install the M5 locking washer to the M5 screw.

Install the M5 hex screw (6 mm long to fit 0.1" thick mounting frame) with the locking washer through 
the tapped hole on the plate support and align it to its locking hole (0.234" diameter) on the mounting 
surface.

Tighten the antenna nut to 60-84 in-lbs or 5-7 ft-lbs.
