Redundancy load module, plug-in card
The redundancy load module does not have a microprocessor, I2C bus or an alarm line. It will not be recognised by the ViaLiteHD SNMP
and web controller or included in the GUI. The alarm line of the module is resistively pulled down.
The
ViaLiteHD
Redundancy load module may have hot surfaces when operating under full load. Suitable precaution should be taken when
handling this device, see safety instructions.
