between the MVME162 and the IP-Dual P/T module. Under these conditions,
a 10° C rise between the inlet and exit air was observed. At 70° C exit air
temperature (60° C inlet air), the junction temperatures of devices on the
MVME162 were calculated (from the measured case temperatures) and did
not exceed 100° C.

aution
For elevated-temperature operation, the user must perform
similar measurements and calculations to determine what
operating margin exists in a specific environment.
The following are some steps that the user can take to help make elevated-
temperature operation possible:
1. Position the MVME162 board in the chassis for maximum airflow over the
component side of the board.
2. Avoid placing boards with high power dissipation adjacent to the
MVME162.
3. Use low-power IP modules only. The preferred locations for IP modules
are position a (J2 and J3) and position d (J18 and J19).
FCC Compliance
The MVME162 was tested without IndustryPacks in an FCC-compliant chassis
and meets the requirements for Class A equipment. FCC compliance was
achieved under the following conditions:
1. Shielded cables on all external I/O ports.
2. Cable shields connected to earth ground via metal shell connectors
bonded to a conductive module front panel.
3. Conductive chassis rails connected to earth ground. This provides the
path for connecting shields to earth ground.
4. Front panel screws properly tightened.
For minimum RF emissions, it is essential that the conditions above be
implemented. Failure to do so could compromise the FCC compliance of the
equipment containing the module.
