Page 9: Preface
The purpose of this document is to provide a procedure to help experienced technicians/engineers install and commission an in-building wireless enhancement repeater system using Westell Technologies digital repeaters. This document was written to address the practical concerns of the installer. Following the procedures in this manual will minimize risks associated with modifying a live system and will prevent service interruptions. -

Page 11: Figure P-1: Product Registration Information
Failure to comply with these precautions or specific warnings elsewhere in the manual violates safety standards of design, manufacture, and intended use of equipment. Westell Technologies assumes no liability for the customer’s failure to comply with these requirements: Grounding: This digital repeater system is designed to operate from 100 - 240 VAC and must always be operated with the ground wire properly connected. -
Page 12: Canadian Compliance Information
Unauthorized use may result in significant forfeiture penalties, including penalties in excess of $100,000 for each continuing violation.” WARNING! Changes and Modifications not expressly approved by Westell can void your authority to operate this equipment under Federal Communications Commission’s rules. -

Appendix B describes the band plans and the convention Westell uses to identify and store the files that make up the filter set. All Westell repeaters are shipped with an active filter set that is programmed according to customer specifications. -
Page 14: Led Indicator
1.3 LED Indicator Westell Technologies automatic safety precautions are built into the amplifier system. In the case of a catastrophic system event, a shutdown circuit will disable all emissions if the uplink input or downlink input is overdriven or if an oscillation or output overpower event occurs. -
Page 15: Local Communication Interface Ports
1.4 Local Communication Interface Ports To allow monitoring and control, Westell repeaters are equipped with four ports that provide external communication access: one ethernet, one DB-9 serial, and two USB ports. The ethernet port is a primary communications port to the PC. -
Page 16: Ethernet
This port is used to provide local or remote access to the GUI. 1.8 Monitoring and Alarms The DSP85 Series can be monitored via an ethernet connection using SNMP, SSH and/or HTTP protocols. Public safety DSP models have dry contacts for traditional alarm panel monitoring as well. -

Page 74: Dsp85-250 And Dsp85-251 Series Mounting
Wall mounting uses four brackets, one at each corner. Figure F-3: Wall Mounting NOTE Westell digital repeaters must be supported in the rack system with a shelf or slide rail. Do not rely on the brackets exclusively to support all the weight of the modules. -

Interconnection of the repeaters in the rack or wall mount configuration requires the short RF jumpers supplied with the CBC Module. The actual interconnections will depend on the bands and cross band coupler module being used. Contact Westell’s technical support line at 1.877.844.4274 should you have questions about your specific application. -
