Eclipse Median Instruction Manual 2 - 1 1
• AES-6. Provides an interface for third party devices and digital
panels.
Each of these interfaces has its own individual manual in the Eclipse
set of manuals. Refer to an interface’s individual manual for more
information on operating, installing, or maintaining it.
Note: Unlike interfaces installed in a separate interface frame, the
interfaces installed in the Median are powered by the same
onboard power supply that also powers the CPU card and
port cards.
POWER SUPPLY DESCRIPTION
Eclipse Median has two Euro Cassette power supply units that you can
easily install or remove as needed. One power supply unit can power
an entire matrix; the second unit provides a backup in case of an
equipment failure.
In addition, the two supplies have separate IEC connectors to AC
mains power, and are designed for completely automatic and
transparent changeover between supplies in the event of an outage on
one of the AC mains circuits. For this feature to work, each power
supply should be connected to a different AC mains branch.
If the temperature inside the Eclipse matrix exceeds a threshold, both
an audible alarm and a warning light switch on, allowing you to
diagnose and correct power anomalies while the system remains in
operation.
Each cassette has two status lights located on the power supply unit in
the upper left corner. The green light stays on continuously to let you
know that the unit is receiving appropriate power. The amber light goes
on when a DC output or AC input falls too low.
DIAGNOSING POWER SUPPLY PROBLEMS
Figure 2-4 illustrates the front panel alarm lights, power supply lights,
and reset button. An alarm source triggers the main alarm light and
also one of the additional six red alarm lights, allowing you to identify
or correct alarm conditions before they affect the operation of the
matrix.
Each of the four green power supply lights stays on continuously to
show that the power supplies are receiving sufficient AC current. When
one of these lights switches off, the power supplies need to be
replaced or repaired.
Under normal operating conditions, the red front-panel alarm lights
stay off, while the green power supply lights stay on continuously.
The power supplies may need to be adjusted if E-Que or fiber cards
are installed. For details of the adjustments please refer to the system
upgrade manual.
