ECLIPSE OMEGA MATRIX INSTRUCTION MANUAL
6-2
DUAL, INDEPENDENT POWER SUPPLIES
The Eclipse Omega matrix includes two Euro Cassette power supply units. 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 a power failure on one of the AC branches.
CAUTION: To reduce the risk of electric shock, plug each of the power cords to
separate branch circuits with different service ground.
POWER SUPPLY ALARM OUTPUT
The power supplies contain an over-temperature sensor that is connected to both
an audible alarm and a warning light, giving you the necessary forewarning to
diagnose and correct any power anomalies while the system remains operational.
If any individual power supply fails, an alarm can be issued to a remote location
to alert operators that part of a power supply has failed. The failure of a single
supply will issue an alarm, but the Eclipse Omega system will continue to operate
normally, powered by the second supply.
“HOT PATCHABILITY”
All CPU cards, port cards, and all Euro Cassette power supplies are “hot
patchable”– that is, they can be plugged in or removed from the matrix while the
power is on, and they will be neither damaged, nor will they cause damage to the
system. In addition, the system smoothly incorporates a newly added card.
Sometimes re-inserting a CPU card can reset the matrix. Replace CPU cards
during maintenance down times if possible.
ONBOARD PROCESSORS
If one port card malfunctions, the malfunction will normally affect only the
panels connected to that port card. The malfunction should not affect any other
cards or panels in the system. In all cases, removing a faulty card affects only the
devices connected to that card.
FAIL-SAFE COMMUNICATION
In the event of a CPU card failure, the second CPU card takes over operation of
the system, while the first card is repaired or replaced.
TROUBLESHOOTING
When attempting to identify the cause of the trouble, it is helpful to begin with
the two most basic areas which cause malfunctions:
• The flow of electric current from the power supplies to the cards.
