MAINTENANCE
INTRODUCTION
The Eclipse Median system connects a complex network of
microprocessor controlled devices. Due to the complexity of the
system, field service should be limted to isolating a problem to the
specific circuit board that may be causing the problem. Once the circuit
board has been identified, it can be either repaired or replaced.
ROUTINE MAINTENANCE RECOMMENDA-
TIONS
MAINTAINING THE MATRIX
Because the matrix has moving air in it, the entire matrix should be
cleaned at least once a year. To clean the matrix, shut off AC power,
remove all cards, and use compressed air to remove any dust buildup
in the matrix itself. Clean all cards with a brush to remove dust buildup.
WARNING: Care should be taken not to induce a static discharge
in the cards. Use of a grounding wrist strap is recommended. If a
grounding wrist strap is not available, touch an unpainted metal
surface on the matrix chassis periodically to neutralize static electricity.
RECOMMENDED SPARE PARTS
To facilitate quick repair of the system with minimum downtime,
Clear-Com recommends keeping the following spare system
components in good working condition at all times:
• One CPU card
• One port card
• One Euro Cassette power supply module of the type fitted to the
matrix
• One of each type of intercom panel in the system
• One of each type of interface in the system
FAIL-SAFE MODES
High reliability is one of the main objectives of the Eclipse Median
system design. The following features of the system minimize the
effects of a component failure.
Due to the complexity of the
system, field service
generally should be limited to
isolating the specific
component with the problem.
