Operating Conditions
Safety
The module presents no hazard to the user.
EMC
The module is designed to operate within an enclosed host system that provides
adequate EMC shielding. Operation within the EU EMC guidelines is only guaranteed
when the module is installed within an appropriate host system.
The module is protected from damage by fast voltage transients introduced along
output cables from outside the host system.
Short-circuiting any output to ground does not cause the host PC system to lock up
or reboot.
General Requirements
The module must be fixed to a TIM40-compliant carrier board.
The SMT376 TIM is in a range of modules that must be supplied with a 3.3v power
source. In addition to the 5v supply specified in the TIM specification, these new
generation modules require an additional 3.3v supply to be presented on the two
diagonally-opposite TIM mounting holes. The lack of this 3.3v power supply should
not damage the module, although it will obviously be inoperable; prolonged operation
under these circumstances is not recommended.
This module is not directly compatible with earlier generations of TIM motherboards,
although the 3.3v supply can be provided from a separate source. It is, however,
compatible with the latest generation of Sundance TIM carrier boards such as the
SMT310Q and subsequent versions (PCI), and SMT328 (VME), which present the
3.3v via conductive mounting pillars.
Use of the TIM on SMT327 (cPCI) motherboards may require a firmware upgrade. If
LED D6 on the SMT376 remains illuminated once the TIM is plugged in and powered
up, the SMT327 needs the upgrade. The latest firmware is supplied with all new
boards shipped. Please contact Sundance directly if you have an older board and
need the upgrade.
The external ambient temperature must remain between 0°C and 40°C, and the
relative humidity must not exceed 95% (non-condensing).
Power Consumption
The power consumption of this TIM is dependent on the operating conditions in terms
of core activity and I/O activity. The maximum power consumption is 3W.
