The SRU 5 is a multi-card enclosure that accepts up to five MARC70 interface modules. The SRU
5 can be mounted either inside or outside the pressure vessel. When less than five interface modules
are used with the SRU 5, cover plates are placed over the unused card slots. If additional cards are
required at a later date, the cover plates can be removed and the appropriate interface card installed.
When installing the SRU 5 ample room should be allowed for both connector clearance and for
inserting and removing the interface modules. The SRU 5 as well as the interface modules can be
mounted in any axis.
1.1.5 SRU 10
The SRU 10 is multi-card enclosure that accepts up to ten MARC70 interface modules. It is ideally
suited for installations that will require more than five interface modules. As with the SRU 5, un
-
used slots are covered with cover plates included in the installation kit. These extra slots can be used
on future installations, eliminating the need for additional mechanical engineering and approval.
The SRU 10 can be installed either inside or outside the aircraft’s pressure vessel. For installation
flexibility, the SRU 10 and the installed interface modules can be mounted in any axis. Ample room
should be allowed for both the connector and for inserting and removing the interface modules.
1.2 TECHNICAL CHARACTERISTICS
The conditions and tests performed for FAA-PMA approval of these articles are minimum perfor-
mance standards. It is the responsibility of the installing agency to determine that the aircraft operat-
ing conditions are within these FAA-PMA parameters.
