2.1.2 Installing the cradle
After mounting the rack mounting rails, install the cradle:
1. Slide the cradle into the rack so it is supported by the L-shaped mounting rails.
2. Fix the cradle to the front rack posts using four M6-screws (not supplied with the unit).
2.1.3 Transporting rack mounted XCUs
When transporting rack mounted XCUs in a flightcase make sure to take the following
precautions:
• Use proper shock absorbers for the rack to prevent damage during transport.
• To prevent any horizontal movement of the cradle and XCU during transport, make sure
there is as little horizontal clearance as possible between the cradle and the mounting
rails:
• To prevent any vertical movement of the cradle during transport, lock up the cradle
between other units and the vertical rail stands as indicated in the illustration below. Make
sure there is enough support at the back of the unit, at a minimum distance of 400 mm
