If one of the power supplies malfunctions, (power cord disconnected, power switch is off, fuse is blown,
rear fan is stopped, etc,) then its PSU STATUS LED will go Off, and the red FRAME STATUS LED on
both power supplies will turn ON. (If the power supplies are fitted with green FRAME STATUS LEDs
they will turn OFF) The PSU STATUS LED on the power supply that is functioning will remain ON. If
the frame is connected to VistaLINK
®
then the power supply fault will send a trap message from the
frame.
If there is a fuse failure,
contact Evertz customer service regarding the
power supply immediately. The power supplies are short circuit protected
and should not blow the fuse under a short circuit condition.
2.7. FRAME STATUS FAULT CONDITIONS
The Frame is fitted with a global Frame Status monitoring buss that is connected to each of the power
supplies and to each of the modules. When a fault condition occurs on one of the power supplies, or
one of the modules, a Frame Status Fault condition is active on the frame status buss. When this
occurs, the red FRAME STATUS LED on the power supply will come on and the relay on the Frame
Status Tally terminal block will activate.
Power supplies, will assert a frame status fault when their PSU STATUS LED is off.
Each module has a large red LOCAL FAULT LED and a large green MODULE OK LED at the top of the
card edge. This green LED indicates good module health while the red LED indicates that there is a fault
condition on the module. Each module has its own criteria that determine when the red fault LED comes
on. When the red LOCAL FAULT LED is On the module can also assert a fault condition on the Frame
Status buss. On each module there is a jumper that disables sending local card fault information to the
Frame Status Buss. For more information about fault conditions on individual modules, and for the
location of the Frame Status Jumper on the module consult the individual chapter for the module. For
example, if a module requires video or audio for its functionality and the video or audio is not present, the
red LOCAL FAULT LED on the module will be On and the fault will be reported on the frame status buss
if the FRAME STATUS jumper on the module is set to the On position (default).
