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 the
system operator 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, expansion 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 analog port interface malfunctions, the malfunction will normally
affect only the panels connected to that analog port interface. 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.
