Preconditions

1 Introduction

This document provides instructions for installing an RBS 2409.

The RBS 2409 can be installed either on a wall, or hanging from a ceiling. Both
stand-alone and master-extension configurations are possible.

Target Group

The target group for this instruction is personnel involved in the installation of
an RBS.

Technicians working on Ericsson products or systems must have the necessary
training and competence required to perform their work correctly.

1.1 Revision Information

Other than editorial changes, this document has been revised as follows:

• Information about chapter Preconditions updated

2 Preconditions

This section provides preconditions that must be met before starting the
installation work.

Documentation

This section presents additional documents required for the installation
procedure.

The following documentation is referenced in this document.

Ensure that the following documents are read and understood:

• Personal Health and Safety Information, 124 46-2885

• System Safety Information, 124 46-2886

Ensure that the following documents are available:

1

41/1531-LZA 701 0001 Uen D 2008-04-23

RBS Installation Instructions

• Completed and approved record prepared during site preparation

• Site Installation Documentation, specific for the site (prepared by the
Installation Engineering department)

• Setting IDB Parameters, 46/1543-LZA 701 0001

• Verifying RBS Installations at Site, 11/1532-LZA 701 0001

General Preconditions

Before starting site work, ensure the following:

• Site access permission has been received

• Ordered RBS, equipment, specified tools and other necessary facilities
have been delivered

• Site power is available

• Transmission line from the BSC is available

If any of the above preconditions cannot be complied with, then contact the site
supervisor or person responsible for the activity that has been missed.

Additional Preconditions for Wall or Ceiling Mounted RBS

Before installing the RBS, ensure that the following preconditions are met:

• The type of fasteners are suitable for the kind of material on which the
RBS is to be mounted

• Vertical installation, which is important for correct cooling

• 100 mm free distance from top and/or bottom, if medium generates heat

• 75 mm free distance from top and/or bottom, if medium does not generate
heat

• 200 mm free distance from the sides

Note: Horizontal distance between two operational BSU is also possible

with less distance. However, the opening mechanism requires
insertion of a tool from the side of the cabinet. So, the actual
minimum horizontal distance is depending on the tool used to
open the cabinet.

If any of the above preconditions cannot be complied with, then contact the site
supervisor or person responsible for activity that has been missed.

4.7 Testing the Installation

The RBS is now ready for verification of the site installation.

The verification must be performed directly after the completion of the RBS
installation, see document Verifying RBS Installations at Site.

After the installation and integration testing is completed, perform concluding
routines as described below.

4.8 Performing Concluding Routines

This section describes the routines to be completed before leaving the site.

Note: Ericsson strongly advises that when cleaning up after installing the

RBS, the personnel performing the installation pay particular attention
to the environment. Primarily, recycle all waste materials that can be
recycled and sort waste so that it can be disposed of according to local
regulations.
