Chapter 8: Maintenance
Replacing DecisioNet Hardware
Except for the ESL battery replacement described in this chapter, the
DecisioNet System hardware does not require any preventive
maintenance. If there is a problem, trained NCR Customer Service
personnel or other trained personnel can use the information in
Chapter 7, "Testing and Troubleshooting," to analyze and isolate the
problem.
DecisioNet hardware is not field repairable. If it is determined that a
CBS, antenna, power supply, or ESL is defective, use the procedures
described in this chapter to replace the unit with a new one. If
appropriate, contact your NCR representative for information on
where to send the defective unit for repair.
Important Information: After removing or replacing the CBS or a
transmit antenna, it is recommended that you re-certify RF
communications. It is also recommended that the change in the site
configuration be noted for support purposes. For more information,
contact your NCR representative and reference the following:
•
DecisioNet Implementation Guide (B005-0000-1250)
•
Certification/Re-Certification Site Survey Policy (497-0410343)
