2. Remove the cable TRENB 101 03 from connection X112 and X113 on the backplane.

3. Remove cable TRENB 101 05 from connector X102 on the backplane, remove the dummy plug

from the connector and connect the cable to connectors X112 and X113. The red wire must be

connected to connector X112 on the backplane (see figure
