switcher’s output; a critical feature should one power source fail during an on air
broadcast.
The Synergy MD-X rack frame uses an N+1 power supply organization. Two power
supplies can provide the complete power requirements of the frame. A third power
supply, purchased with this option, adds redundancy in the event that one power source or
power supply is lost. All rack frame power supplies are fully hot swappable without
affecting switcher operation.
The fourth power supply slot is not used at this time.
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
• Supply 3 failure
• Supply 4 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.
Spare Parts Kit S4MDX-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 and
is easily repairable in the field.
• The part is used in system power management and is easily repairable in the field.
• The part can be lost easily.
Parts that fall outside of the above criteria are not included.
An exception to the above criteria is rack frame and control panel power supplies. These
are expensive parts and spares are ordered separately.
Note: A major item included in this kit is a loaded replacement system hard disk drive.
This Ross-approved 80GB drive contains boot software, Linux OS, switcher system
software, and standard video images. For critical on air applications, this option is
recommended.
