additional warning as to the director’s next move. “Green” tallies require the purchase of
the Extended Tallies option.
Redundant Power (Frame and Panel) S2-071A
The redundant power supply option provides protection against AC power failure. It allows
the switcher to receive power from two independent power sources. Complete failure of
one source will not affect the operation of the switcher in the slightest. If the main AC
power fails, the switcher instantly draws power from the remaining source. The transition
from one power source to the other is totally transparent and has no affect on the switcher’s
output; a critical feature should one power source fail during an on air broadcast.
There are two power fail indicator lights on the main panel. They indicate the following:
• loss of redundant power in the rack frame,
• loss of redundant power in the control panel.
In the rack frame, there are lights visible from the front of the unit that indicate the
following:
• All okay
• Supply 1 failure
• Supply 2 failure
• Cooling fan failure
Adding redundant power does not increase the amount of rack space required by the
switcher. It mounts inside the main electronics chassis.
Extender Board S2-072
The Extender Board is a printed circuit board having electrical contacts on the front and
back ends, but no components. It can be installed into any board slot in the rack frame. It
allows technicians easy and convenient access to any of the switcher’s video processing
boards allowing these boards to be powered up while outside of the rack frame.
All of the video processing boards in the Synergy switcher are mounted horizontally, not
vertically, making them convenient to work on.
Note
There are no adjustments on any of the switcher’s video processing
boards, as all of the circuitry is fully digital. The extender board is only
required for troubleshooting failures and as such should only be used
by a qualified technician.
Spare Parts Kit S2-073
It would be far too expensive to put every switcher part in the Spare Parts Kit. Parts were
chosen for the kit using the following criteria:
• The part comes into frequent contact with the user.
• The part can be easily damaged or may wear out with excessive use.
• The part can be damaged by connecting excessive voltage to an external connector.
• The part is used in system power management.
• The part can be lost easily.
ICs that fall outside of the above criteria are not included.
