2.2.4 Host System Card
The System Card contains the fan controller, the clocking circuitry (internal or
external), the temperature sensor and the DCC contacts. Its front panel provides
connections for alarm outputs, 10 MHz output, and status LEDs. This card may be
used to provide a 10 MHz clock reference to which the SeRF's Master clock is
frequency locked from the internal crystal oscillator. When the internal clock is not
used the clock can be obtained from an external 10 MHz input.
