Installation

6.1 Inventory

The first thing an installer physically does once onsite is to check to see that all equipment and materials
have arrived, as well as to make sure all necessary documents and forms are available.

6.2 BWX 8415 Basestation Radio Unit (RU) Installation

6.2.1 Overview

Caution Only trained and qualified personnel should be allowed to install, replace, or service this

equipment. Statement 1030

OL-19519-01

Caution - Refer installation and service to qualified service personnel only. No user serviceable parts inside.

- Installation must be done in accordance with the instructions contained in this manual.

- Read these instructions before installing.

- Save these instructions.

Warning

Installation of the equipment must comply with local and national electrical codes.

The Radio Unit (RU) is a lightweight unit that connects easily with the Antenna Unit (AU) to form the
complete BWX 8415 Basestaion (BS). All customer accessible connectors will be located on the bottom
of the RU (

Note that the circuit cards inside the BS are not field replaceable. Therefore, if a severe fault occurs, the
entire unit is removed and replaced. The design intent is to cut down on the time it takes to troubleshoot
or otherwise have a field support person onsite.

The fiber-optic port, console port (RJ-45 connector), GPS antenna port, and the DC power connections
(two -48V, 2 RTN, and one GND) are located on the bottom of the RU.

At no time should a field person remove the RU’s cover or otherwise open the unit. In fact, doing so
may void the warranty.

6.2.2 BWX 8415 Basestation Radio Unit Field Testing

PRELIMINARY

6.2.2 BWX 8415 Basestation Radio Unit Field Testing

THIS SECTION WAS WRITTEN/DEVELOPED, BASED ON THE FIELD TEST KIT LIST OF
MATERIALS AND VERBAL DESCRIPTIONS OF HOW THE FIELD TEST KIT IS INTENDED
TO BE USED. ONCE THE FIELD TEST KIT IS DEVELOPED, THIS SECTION WILL BE
UPDATED TO REFLECT THE ACTUAL EQUIPMENT.

It is recommended that the RU be tested, to ensure that the unit is functioning properly, prior to
installation into the AU. Perform the following steps to connect the RU to the Field Test kit and test the
RU.

Step 1 Connect the RU to the Fan/Cal Board assembly. Refer to Figure 6-2.

- Connect the RU to the fans/cooling system

- Connect the RU to the Cal board (using the 9 RF cables included in the Field Test kit)

- Connect the GPS antenna to the GPS Antenna port on the bottom of the RU.

Figure 6-2 RU to Fan/Cal Board Assembly Connection

Step 2 Connect a ground cable to the RU ground. Tighten the nuts to 48 in. lbs. (5.4 Nm). Refer to Figure 6-3.

Step 3 Connect the DC power cable leads (2 RTN and 2 -48V) to the RU. Tighten the nuts to 48 in. lbs.

(5.4 Nm). Refer to Figure 6-3.

Figure 6-3 Ground Cable and DC Power Cable Connections

Step 4 Connect an RJ-45-to-DB-9 serial cable to the Console port on the RU and to the Field Technician’s

laptop PC.

- Using a terminal application (such as TeraTerm or Hyperterminal), set the following port
parameters:

Baud Rate: 9600
Data: 8 bit
Parity: None
Stop: 1 bit
Flow Control: None

OL-19519-01

Step 5 Power up the RU by connecting the DC power cable to a DC power source (48V power supply).

Note Once the RU is powered up, it will begin to boot. The boot process can be monitored from the terminal

application on the laptop PC.

Step 6 Modify the bootline parameters as necessary. (MORE DETAILS ONCE FIELD TEST KIT IS

Step 7 Once the bootup is completed, perform a calibration to verify the RU is functioning properly. (MORE

DETAILS ONCE FIELD TEST KIT IS AVAILABLE)

Step 8 After the calibration has been completed successfully, power down the RU. Disconnect the RU from the

DC power source.

Step 9 Disconnect the ground cable and DC power leads from the RU.

Step 10 Disconnect the RF cables and GPS cable from the RU.

Step 11 Disconnect the fans/cooling system.

Warning

Do not work on the system or connect or disconnect cables during periods of lightning activity.

Statement 1001

Warning

Step 1 Remove the two lower faceplate covers on the back of the AU, to access the RF calibration board and

Ensure that the power to the RU unit is OFF before installing the unit into the AU.

RF Calibration Board Mechanical Interlock Pin Holes

Caution Do not attempt to insert the RU into the AU without removing the lower faceplate covers. These faceplate

covers have a mechanical interlock pin, which inserts into the RU, and if the faceplate covers are not
removed when inserting the RU, damage could occur to the RU and the mechanical interlock pins.

Step 2 Insert the RU into the AU, as shown in Figure 6-5.

Step 3 Connect the RF cables and the Cal cable, coming from the RF calibration board, to the RF connectors

and Cal connector on the RU unit.

Step 4 Replace the faceplate covers. Be sure to insert the pin on the faceplate covers into the mechanical

interlock holes on the AU and RU units, these holes should align when the RU is inserted into the AU.

Caution Ensure that the faceplate covers are properly secured to prevent water from leaking into the unit.

Step 5 Install the lower manifold.

Caution Ensure that the lower manifold is properly secured to ensure that the air flow for the heat exchangers is

contained within the unit.

Step 6 Install the I/O cable cover. (It is not necessary to completely tighten these covers at this time. The covers

are being installed to prevent them from swinging while the BWX 8415 Basestation is being hoisted.)

Step 7 Once installed, proceed to the next section of this Guide.

Note To remove the RU, after it has been installed, refer to Appendix F, “Radio Unit Removal”.
