11 Maintaining the
Eclipse HX-Median
The Eclipse HX-Median matrix system connects a complex network of microprocessor
controlled devices.
Due to the complexity of the system, field service should be limited 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.
Tip: For an overview of the Eclipse HX-Median, see 3 Overview .
Servicing instructions are for use by qualified personnel only. To reduce the risk
of electric shock, do not perform any servicing other than that described by this
guide, unless qualified to do so. Refer all servicing to qualified service
personnel.
11.1 Routine maintenance recommendations
11.1.1 Cleaning the matrix frame
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.
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.
