WJ Broadband Fixed Wireless System Transceiver Installation and Replacement Instructions Product Numbers: SX1121, SX1121A, SX1123, SX1123A, SX1126, SX1127. This document explains how to install, remove, or replace the standard power wireless transceiver component of a broadband fixed wireless system. It includes instructions for powering down the system, removing an installed transceiver, and installing a new transceiver.
Wireless Transceiver Overview The wireless transceiver (often referred to as the outdoor unit or MODULO) is the control and data interface 10 the indoor router subsystems.
Table 1. Wireless Transceiver Connectors Connector Type Input/Output Function Antenna connector N-type weatherized (female) Input and Output Antenna connection IF Input/ Control/Power ~~ N-type weatherized (female) Input and Output Carries receive and transmit IF signals, power, IF reference frequency, and RF subsystem control interface Installation Prerequisites This section provides a list of parts and tools you need to install, reprove, or replace a wireless transceiver at the antenna site.
Safety Guidelines Following are safety guidelines that you should follow when working with any equipment that connects to electrical power or telephone wiring.
Electrical Equipment Guidelines dA Ad Follow these basic guidelines when working with any electrical equipment: + Disconnect ali power and external cables before moving a chassis. + Do not work alone if potentially hazardous conditions exist. « Never assume that power has been disconnected from a circuit; always check.
Table 2, Warning Antenna Installation Instructions: FCC RF Exposure Limits The WJ SX1121 and SX 1123 transceivers, used in conjunction with 18 and 24 dBi gain antennas, are to be employed in point -multiplication applications only. The transceivers are either provided with an integral antenna, or provided without an integral antenna.
Installing the Wireless Transceiver This section provides instructions for installing the transceiver on the desired platform. NOTE: These instructions apply to the transceiver manufactured and supplied by Watkins-Johnson Communications Inc. Transmit and Receive Frequencies The standard power transceivers are provided with the transmit frequency and the receive frequency set at the factory. Each model can be supplied with transmit on the high frequency band or transmit on the ow frequency band.
* Attach ground lug supplied in mounting kit to an approved ground wire. Then attach ground lug to chassis. {See Figure 3). Figure 3. Location to attach ground lug on transceiver ADD PICTURE HERE OF 8X112X WITH NEW GROUND LUG MOUNTING LOCATION SHOWN Step 4 Attach transceiver to bracket, ® Use the mounting hardware included in the mounting kit to bolt the transceiver to the bracket. Always use one lock washer and one flat washer for each mounting bolt.
PROCEDURE 2 (For pole mounted transceiver without integrated antenna) Step 1 Fasten gray mounting arm to wall or to horizontal surface. Step 2 Mount unit to wall or flat surface Step 3 Attach mounting foot to arm using U-bolts.
Step 1 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 6.) 1f necessary, use the spacers provided. This will be the bracket that holds the top of the transceiver. Figure 6 Attaching the Top Mounting Bracket to the Antenna Mast Antenna mast —m| Spacer (optional) “85 o @ Step 1 Using a wrench, attach the transceiver to the top mounting bracket using 3/8" nut, flat washer, and lock washer.
Cabling the Wireless Transceiver A A Warning Ensure that the power/breaker switches (on the power feed panel) for both the Main and Diversity transceiver are in the OFF position. 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 to the transceiver connector marked IF/DC CONTROL INPUT, Tighten the connection with an adjustable wrench or pliers. Figure 7. IF/DC Control Cable Connection Connecting the Antenna Cable for Units without Integrated Antenna Connect the Antenna cable to the transceiver connector marked ANTENNA. Tighten the connection with an adjustable wrench or pliers.
This completes the procedure for installing and cabling a wireless transceiver. Removing and Replacing the Wireless Transceiver Follow these instructions to remove and replace the wireless transceiver.
Time saver To make replacement easier, be sure all cables are labeled. Step 1 Remove the RF cable leading to the antenna. Step 2 Remove the Contradiction} cable. Removing the Wireless Transceiver from the Antenna Mast Follow these steps to remove the wireless transceiver from the antenna mast: Step 1 Remove the hardware securing the bottom U-bolt to the mast (see Figure xx), and remove the U-bolt from the mast.
Replacing the Wireless Transceiver Replacing the wireless transceiver involves the following tasks: Step | Mounting the Wireless Transceiver on the Antenna Mast Step 2 Attaching the Cables Step 3 Reinstating the Power Remounting the Wireless Transceiver on the Antenna Mast Mount the replacement transceiver on the mast using the instructions in the section of this document called Installing the Wireless Transceiver.
