 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
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.
Step 1.
Install 10 cage nuts into the desired 1U slot of the rack: 4 cage nuts in the non-extractable side
and 6 cage nuts in the extractable side.
Step 2.
Mount both of the outer rails (C+D) into the rack (as illustrated in Figure 14), and use 8 stan-
dard pan-head screws (E) to fix them to the rack. Do not tighten the screws yet.
Step 3.
If cable accommodation is required, rout the power cable and/or Eth cable through either of the
outer rails.
Step 4.
Secure the switch to the left and right inner rails (A+B), by gently pushing the switch chassis’
pins through the slider key holes, until locking occurs.
Step 5.
Secure the chassis in the inner rails screwing the 2 flat head Phillips screws (F) in the desig-
nated points.
