2.5 Environmental Limitations
The MCPA is designed to operate in an environment as noted in Table 1 of this
manual. The MCPA must be installed in an area where an adequate and unrestricted
supply of air is available for cooling. Adequate clearance must be provided to prevent
obstruction of airflow. Confirm that proper dc power is available for the equipment.

The amplifier is produced in a Blind Mate configuration as shown in Figure 2. The
Blind Mate configuration is designed for mounting in an Ericsson Amplifier
Technologies subrack, and features a single connector on the rear panel for all RF, DC
and I/O interface connections. The following paragraphs provide installation details.
