This is normal when the MSD is initially turned on. The status lights will blink until the data system software is started or the pumpdown cycle is initiated. The data system then downloads the instrument control software to the LAN control card. When this occurs, the status LEDs will all light for a few seconds and then begin to operate normally, leaving the power LED on and the others off. If the status LEDs do not stop blinking, one of the following may be the cause:
A momentary loss of power to the MSD can interrupt communication between the MSD and the data system. This will cause the status LEDs to blink. A longer interruption will cause the MSD to shut down. When the power is restored, the MSD automatically pumps down but communications are not automatically reestablished so the status LEDs will blink. Reinitialize communication between the MSD and the data system.
A software malfunction can interrupt communications between the MSD and the data system. This will cause the status LEDs to blink. Reinitialize communication between the MSD and the data system.
Make sure the LAN cable is connected between the MSD and the data system.
Make sure the LAN cable is securely connected at both ends.
If that does not correct the problem, replace the LAN cable.
Reinitialize communication between the MSD and the data system.
