Multi-Modular I/O System
Clock Master LED
The Clock Master LED indicates that a Pro64 device is providing the master clock sync for the Pro64 network.
When an F6 Modular I/O Frame is used as the network’s Control Master, it automatically becomes the Clock
Master. With at least one C4dio Digital I/O card installed in the F6, external clocks can also be used to sync the
network. External clock choices include Word Clock or the clock embedded in an AES3 digital stream.
Thermal Monitor LED
The F6 Modular I/O Frame constantly monitors its internal temperature as well as the status of its built-in fan unit.
If the device’s internal temperature gets too high, the Thermal Monitor LED will begin to blink to indicate that
temperature of the F6 and its surrounding enclosure should be checked. If the temperature continues to rise,
the LED will light solid when the temperature reaches an unacceptable level. Correct the ambient temperature
problem as soon as possible to avoid damaging the product.
Fan Monitoring
The Thermal Monitor LED is also used in conjunction with the onboard firmware to monitor the condition of
the built-in fans used to keep the F6 cool. In case of a fan failure, the yellow LED will blink slowly to indicate the
problem. Replace the fan as soon as possible if this warning occurs. The Fan6 Replacement Fan Tray Assembly is
an optional accessory that is an exact replacement for the standard fan assembly in the F6.
Error LED
This red LED will be activated by software when a hardware error is detected. For example, if an unrecognized I/O
card is installed, the Error LED will flash to indicate the incompatibility. Updating the F6 firmware and/or version
of the Pro64 Network Manager software should correct and clear this error state.
