Setting up and operating the BUC system
Block Up Converter Systems 6700/6900 series User Guide 79
Warm standby
In warm standby, only the power amplifier of the on-line BUC
is activated. This provides a lower power consumption than
the hot standby system. The power amplifier of the off-line
BUC is automatically activated when the stream switches to
on line.
To set the BUCs to operate in warm standby:
1 Set the Redundancy mode to Warm standby using
a Hand-held Controller 6560, a Remote Controller 6570,
or serial commands on a PC running terminal-emulating
software.
NOTE
Codan recommends that you set the
Redundancy mode of both BUCs to
Hot standby. This keeps the off-line
stream in hot standby ready for immediate
operation. It also enables detection of
faults in the power amplifier of the off-line
BUC through the normal fault detection
system, or via the transmit power alarm
threshold facility.
