12 • Broadcast Time Delay
Front Panel Features
Power ON/OFF button
The blue front panel button initiates start-up and shut-down of the Broadcast Time Delay. Press it
momentarily to start the server. A sequence of start-up screens will appear, ending with the 3-channel
graphic user interface.
When the Broadcast Time Delay is running, pressing the blue button momentarily will cause the
system to begin an orderly shutdown. This can also be initiated from the GUI by selecting
START > SHUTDOWN > SHUTDOWN. In most cases the power will shut off automatically,
however if the front panel lights begin to blink the file system has been properly closed and it is safe to
force the power off by holding the front panel button in for 4 seconds.
In the event that the system has stopped responding to commands and will not shutdown, hold the
button in for 4 seconds to force a power down.
Do not use the rear panel switch on the power supply to shut down the Broadcast Time Delay. Abrupt
power loss can cause loss of information stored on the disk array. The rear panel power switch can be
used to prevent re-application of power during service procedures once the normal shut down
sequence is complete.
CAUTION:
LOSS OF DATA CAN OCCUR IF THE POWER IS TURNED OFF WITHOUT A SHUTDOWN.
USE THE FOUR SECOND SHUTDOWN ONLY IF THE SYSTEM IS NOT RESPONDING OR THE
SHUTDOWN PROCESS DOES NOT TURN THE POWER OFF AUTOMATICALLY.
Indicators
Five blue LED Status Indicators appear on the front panel. These indicators are illuminated
continuously when the system is functioning normally. See the table Front Panel Indicators on page
30 for diagnostic meanings.
The Status Indicators are also available as GPI outputs, along with additional output warnings for loss
of input and loss of genlock. See GPI Interfacing for details.
