3 Chapter 3: Installing the Hardware Infrastructure Chapter Overview This chapter describes how to install the DecisioNet hardware infrastructure. This includes the following components: • CBSs • CBS power supplies • Data and power cables • Transmit and receive antennas For information about ordering these parts, refer to Appendix A. After the DecisioNet hardware is installed, the DecisioNet software must be configured and the site must be RF certified.
3-2 Chapter 3: Installing the Hardware Infrastructure Installation Recommendations • The most efficient way to install the DecisioNet hardware infrastructure is in one pass through the store. Install the CBSs, antennas, power cables, and data cables all at the same time • Label all cables and document labeling for future reference. • Neatness makes servicing the system much easier. • Allow slack in cables, especially in receive antenna cables. • Test the system as it is being installed.
Chapter 3: Installing the Hardware Infrastructure 3-3 General Layout Instructions • The cable length between any two devices (hub to CBS or CBS to CBS) cannot exceed 100 m (328 ft.). • The maximum number of Ethernet levels beyond the primary CBS is three (3). • The maximum total cable length is as follows: Cable Maximum Cable Length Ethernet (primary CBS to last CBS in chain) 300 m (984 ft.) Power supply to last CBS in the chain 162 m (532 ft.) • Use only NCR authorized communication cable.
3-4 Chapter 3: Installing the Hardware Infrastructure • The minimum distances between a communication cable and electrical equipment/associated power cables are as follows: Maximum Rated Circuit Power Unshielded Power Cables Shielded Power Cables 1 kVA 2 kVA 5 kVA Over 5 kVA 30.5 cm (14 in.) 45.7 cm (18 in.) 60.9 cm (24 in.) 152.4 cm (60 in.) 2.54 cm (1 in.) 5.08 cm (2 in.) 15.24 cm (6 in.) 30.48 cm (12 in.
Chapter 3: Installing the Hardware Infrastructure 3-5 CBS Installation The following sections describe the preparation, cabling, and installation of the CBS and its related components. CBS Ethernet Cable Connections The Release 3.0 CBS uses a star topology and has an integrated Ethernet hub that can connect to three other CBSs. DecisioNet III supports up to three (3) levels below the primary CBS. This topology results in the 40 CBS maximum mentioned in the General Layout Guidelines section.
3-6 Chapter 3: Installing the Hardware Infrastructure CBS Numbering CBS’s are identified in the CBS Manager section of the DecisioNet CBS configuration file (DNCBSCONFIG.XML) with a unique number (1-99) and a host name or IP address. Using the numbering scheme shown in the illustration helps identify the level in which the CBS is connected in the topology when running diagnostic tests and analyzing diagnostic logs.
Chapter 3: Installing the Hardware Infrastructure 3-7 CBS Power Supply Cable Connections The CBS Power Supply can support up to five (5) CBSs, however, power requirements in EU/EC countries limit the number of CBSs connected to a power supply to three (3). The following illustration shows an example power supply wiring scheme for a 14 CBS nonEU/EC configuration.
3-8 Chapter 3: Installing the Hardware Infrastructure EU/EC Installations Power requirements in EU/EC countries limit the number of CBSs connected to a power supply to three (3). The following illustration shows power supply cable connections for a 12 CBS configuration using 4 power supplies. This cabling scheme may be extended to support 40 CBSs.
Chapter 3: Installing the Hardware Infrastructure 3-9 Sample Store Cabling The following illustration shows a non-EU/EC country store layout with 13 CBSs and 3 power supplies. Ethernet and power supply cables originate in the back office and are bundled together to accomplish this configuration.

Chapter 3: Installing the Hardware Infrastructure 3-11 Power and Data Cables The power and data cables must be purchased in bulk from a third party. NCR recommends using the Belden cables described in the following table. Comparable cables from other manufacturers are acceptable. The wire colors referenced in the text and illustrations that follow are consistent with the recommended Belden cables. If you are using a comparable cable from another manufacturer, your wire colors may be different.
3-12 Chapter 3: Installing the Hardware Infrastructure Power Cable Connectors Each CBS is shipped with a 4-wire connector that plugs into the 8-wire power receptacle. The only tool required to install the power cable into the connector is a small screwdriver. Data Cable Connectors An RJ45 connector is required for each of the CBSs data connectors. The RJ45 connectors must be purchased from a third party. A crimp tool is required to install the data cable into the RJ45 connector.
