
Planning the system’s placement in the rack
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
important 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
2” (5.08cm) 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.

Mounting the slides to the system
Step 1.
The recession feature is bi-directional, meaning that you can recess the system either backward
or forward.
Step 2.
Screw the system slides onto the system. Use 5 flat head 6-32 screws for a short system and 7
screws for a standard depth system to connect each system slide. The recommended tightening
torque is 1.5±0.2 Nm.

Step 3.
Clip the caged nuts into the holes in the rack on the side of the rack you will be sliding the sys-
tem into.
5 screws per side are needed for the short system.
7 screws per side are needed for the standard system.
If using a torque screwdriver to tighten the screws, set it to 1.5±0.2 Nm.
