To separate the rails:
1. Extend the rail assembly by pulling the extension outwards (D).
2. Extract rail A from rail C by pushing it outside from the rear part of the assembly. To allow com-
plete separation of rail A from rail C, press the quick-release latch.
Before mounting the system to the rack, select the way you wish to place the system. Pay atten-
tion to the airflow within the rack cooling, connector and cabling options.
While planning how to place the system, review the following points:
• Make sure the system air flow is compatible with your installation selection. It is import-
ant to keep the airflow within the rack in the same direction.
• In case there are cables that cannot bend within the rack, or in case more space is needed
for cable bending radius, it is possible to recess the connector side or the FRU side by 3"
or 4" (7.62 or 10.16cm) by optional placement of the system's rails.
• The FRU side is extractable. Mounting the sliding rail inverted to the system will allow
you to slide the FRU side of the system, in and out.
Insert 10 cage nuts into the desired slots of the rack: 4 cage nuts in the non-extractable side

and 6 cage nuts in the extractable side.
