Euphonix CO-600 Change-Over System For New Core DF66 Redundancy
11
Detailed Description and Service Info
The Change-Over System (COS) Chassis is designed to provide automated or manual
switching between redundant MADI streams in a critical production environment. It
does this by grouping redundant MADI media in sets of 4 MADI ins and 4 MADI outs to
be switched as a whole, then allowing up to four groups be switched by a single chassis.
Multiple Chassis can be daisy chained for larger scale systems. Various mechanisms
provide for the automatic and manual switching. Slots are keyed to avoid insertion of
the wrong card.
Power Supply
A single power supply card can be installed into either one of the top two right slots in
the COS chassis. Make sure the ejector clips are completely latched. Be careful during
installation that the card is aligned in the slot grooves for the card.
Due to the thickness of the pins used to connect the card to the chassis back plane,
some insertion force will be necessary. Press on the card front with your thumbs while
operating the ejectors to help get the ejectors latched. This will prevent excessive wear
on the plastic ejector mechanism.
Be aware that there is a specific IEC power connector on the rear of the chassis for each
power supply. The power supply card will only operate if the correct IEC power cord
is connected.
If two power supply cards are installed, they can be installed in either order.
Controller Card
Only one Controller card (FC 603) can be installed in a chassis. Install a Controller
Front in the bottom front controller slot on the right side of the chassis.
Make sure the ejector clips are completely latched. The card should not require excessive
force to insert, if the card does not seem to insert, check that the card is sliding evenly in
the slot grooves and that the alignment pins near the ejector clips are guiding card during
the last portion of insertion.
Install a Controller Rear card (FC 605) in the bottom rear controller slot on the right side
of the chassis. Use the same care in installing the rear card as the front card. Make sure
the ejector clips are completely latched.
Do not attempt to plug a Controller front/rear card into the identical CMM slot above it.
The cards may be damaged, and unexpected operation will occur.
