WJ Broadband Fixed Wireless System Transceiver Installation and Replacement Instructions Product Numbers: S$X1122, S$X1124. This document explains how to install, remove, or replace the wireless transceiver component of a broadband fixed wireless system.
Wireless Transceiver Overview The wireless transceiver {often referred to as the outdoor unit or ODU) is the control and data interface 10 the indoor router subsystems. It provides up/down conversion for IF to RF frequencies and power amplification. The wireless transceiver consists of the following components: « RF head + Connector port for IF input/output, control, and test « Ground lug Figure 1 shows the connectors on the wireless transceiver, and Table 1 describes their use.
Installation Prerequisites “This section provides a list of parts and tools you need to install, remove, or replace a wireless transceiver at the antenna site. This section also includes safety and EDS-prevention guidelines to help you avoid injury to yourself and damage to the equipment. Parts and Tools You need the following tools and parts to install, remove, or replace the transceiver. If you need additional equipment, contact a service representative for ordering information.
Warning Do not locate the transceiver near overhead power lines or other electric light or power circuits, or where it can come into contact with such circuits. Warning This unit is intended for installation in restricted access areas. A restricted access area is where access can only be gained by service personnel through the use of a special tool, lock and key, or other means of security, and is controlled by the authority responsible for the locations.
Antenna Installation Instructions: FCC RF Exposure Limits The WJ 8X 1122 and SX 1124 transceivers, used in conjunction with 18 34 dBi gain antennas, are to be employed in point -to point applications only. Antennas used for these transmitters shall be professionally installed on permanent structures for outdoor operations. The installer is responsible for ensuring that the systems using high-gain, directional antennas are used exclusively for fixed, point-to-point operations.
Installing the Wireless Transceiver This section provides instructions for installing the transceiver on the antenna mast. Nate These instructions apply to the transceiver manufactured and supplied by WI. Transmit and Receive Frequencies The SX 1122 and SX 1124 are provided with the transmit frequency and the receive frequency sel at the factory. Each model can be supplied with transmit on the high frequency band or transmit on the low frequency band.
Step 3 Repeat this process for the other side of the mounting bracket. Step 4 Install shock mounts on fo the bracket assembly (2 places) using the #6 hardware supplied. Tighten all screws. (See Figure 8.) Figure Attaching the Shock Mounts to the Adapter Plate #6 flat washer, split, and bolt Step 5 Install this bracket assembly to the lower portion of the wireless transceiver using 5/16” hardware supplied. Counter torque may need to be applied to the cup of the shock mount when tightening the bolt.
Step 6 Place a 3/8" bolt through an adapter plate and then install the shock mount on 10 the adapter plate using #6 hardware and tighten. The 3/8” bolt will be loose but captive in the assembly. Assemble the other shock mount as well. (See Pig are 10) Figure 10 Assembling the Shock Mount Assembly #6 bolt, flat washer, lock washer Step 7 Install the shock mount assemblies on to the holes at the top of the transceiver using 5/16” hardware. The transceiver is now ready to mount on to a pole. (See Figure 11.
Step 8 Select the appropriate size U-bolt from the mounting kit and attach the remaining mounting bracket to the antenna mast using 3/8” hardware and tighten. (See Figure 12.) If necessary, use the spacers provided. This will be the bracket that holds the top of the transceiver. Figure 12 Attaching the Top Mounting Bracket to the Antenna Mast Za. soccer options) 2 ¢g @ Step 8 Using a wrench, attach the transceiver Lo the top mounting bracket using 3/8" nut, flat washer, and lock washer. (See Figure 13.
Figure 13 Attaching the Transceiver to the Pole a) Loosely install 5/16” nut, and washers. b.} Spin the 5/16” mounting bolt until the head of the bolt locks in place. Tighten the 5/16” nut while the bolt is locked in place. Caution Do not leave the transceiver unattended until ail the fasteners have been tightened.
Step 10 Tighten all fasteners to 15 foot-pounds of torque. Cabling the Wireless Transceiver Warning Ensure that the power/breaker switches (on the power feed panel) for both the Main and Diversity transceiver are in the OFF position. Attaching the Ground Lug A ground lug kit is provided with the transceiver. Use the following steps to attach the ground lug to the transceiver chassis. Step 1 Attach an approved ground wire to the ground lug.
Warning Cisco and WJ strongly recommend that you use some type of cable-connection weatherproofing on all outdoor RF and IF cable connections to protect them against long-term degradation from weather effects. This is typically done by applying a suitable seal to the N-type connectors after they have been connected and verified.
Connecting the IF/DC Cable Connect the IF cable 10 the transceiver connector marked IF/DC INPUT. Tighten the connection with an adjustable wrench or liars. Figure 24 1F/DC Cable Connection Connecting the Antenna Cable Connect the Antenna cable to the transceiver connector marked ANTENNA. Tighten the connection with an adjustable wrench or liars. Consult the instructions provided by your antenna manufacturer for additional instructions on installing antennas.
A Warning After cabling, reinstate power . This completes the procedure for installing and cabling a wireless transceiver.
Time saver To make replacement easier, be sure all cables are labeled. Step] Remove the RF cable leading to the antenna. Step Remove the IF/DC/Control cable, Step Remove the screws from the ground lug. (See Figure 26.) Figure 26 Removing the Ground Lug Removing the Wireless Transceiver from the Antenna Mast Follow these steps to remove the wireless transceiver from the antenna mast: Ste pl Remove the hardware securing the bottom U-bolt 10 the mast (see Figure 27), and remove the Bolt from the mast.
Figure 27 Inventorying the Bottom and Top U-bolts J Step Leaving the hex bolts in place, carefully remove the hex nuts, lock washers, and flat washers from the back of both sides of the top mounting bracket. (See Figaro 27.) Step Carefully remove the wireless transceiver from the top bracket and move it to a work area. f ‘Warning Do not leave the transceiver unattended while the fasteners are removed.
Replacing the Wireless Transceiver Replacing the wireless transceiver involves the following tasks: 1 Mounting the Wireless Transceiver on the Antenna Mast 2 Attaching the Cables 3 Reinstating the Power 4 Initiating the Wireless Link Remounting the Wireless Transceiver on the Anterior Mast Mount the replacement transceiver on the mast using the instructions in the section of this document called Installing the Wireless Transceiver.
