Reference Materials (MSER)
Maintenance Philosophy
The EBTS has been designed using a Field Replaceable Unit (FRU) maintenance
concept. To minimize system down time, faulty FRUs may be quickly and easily
replaced with replacement FRUs. This helps to restore normal system operation
quickly.
Due to the high percentage of surface mount components and multi-layer circuit
boards, field repair is discouraged. Faulty or suspect FRUs should be returned to
the Motorola Customer Support Center for further troubleshooting and repair.
Each FRU has a bar code label attached to its front panel. This label identifies a
sequential serial number for the FRU. Log this number whenever contacting the
Motorola Customer Support Center. For complete information on ordering
replacement FRUs, or instructions on how to return faulty FRUs for repair,
contact:
