General specifications for the MVME177 are listed in Table
The following sections detail cooling requirements and FCC compliance.
Cooling Requirements
The Motorola MVME177 VMEmodule is specified, designed, and tested to operate reliably with an incoming air temperature range from 0û to 55û C (32û to 131û F) with forced air cooling at a velocity typically achievable by using a 100 CFM axial fan. Temperature qualification is performed in a standard Motorola VMEsystem chassis.
While the exact amount of airflow required for cooling depends on:
❏Ambient air temperature
❏Type of board
❏Number of boards
❏Location of boards
❏Other heat sources
adequate cooling can usually be achieved with 10 CFM and 490 LFM flowing over the module. Less airflow is required to cool the module in environments having lower maximum ambients. Under
