When S1-1, S1-2, and S1-3 are used to set the subnode address, make sure that the DIP switch settings
are consistent with the data configuration. But the subnode address value cannot be the same as that of
the environment monitoring board.
Fan Speed Adjustment
Set the fan speed adjustment mode to "automatic" or "manual" in the command line interface
(CLI). After the fans are installed, they work in automatic mode by default.
l Automatic mode
– Control-system-triggering: The control system automatically adjusts fan speed
according to the board temperatures for energy conservation.
– Monitoring-board-triggering: Electric switches 7 and 8 of the SW2 DIP switch on
the monitoring board are set in four different ways to achieve four speed adjustment
policies (the ETSI subrack supports only the third policy).
NOTE
The automatic mode has two variants (automatically selected by the system): control-system-
triggering and monitoring-board-triggering.
l Manual mode
