Installation

 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 attention 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.

Step 3.

Step 4.

Mount both of the outer rails (C) into the rack (as illustrated in Figure 9), and use 8 standard

pan-head screws (D) to fix them to the rack. Do not tighten the screws yet.

If cable accommodation is required, rout the power cable and/or Eth cable through either of the outer rails.

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. Secure the chassis in the inner rails screwing the 2 flat head Phillips screws in the designated points.

Step 5.

Step 6.

Slide the switch into the rack by carefully pushing the inner rails into the outer rails installed on the rack.

When fully inserted, fix the switch by closing the remaining 2 screws in the middle and tightening the 8 screws inserted in Step 2 with a torque of Min 2Nm.

2.4.2.1 Removing the System from the Rack

 To remove a unit from the rack:

Step 1.

Unscrew the two M6 screws securing the front of the inner rails’ ears to the outer rails and to the rack.

Step 2.

Step 3.

Pull the unit out until braking is felt. For safety purposes, the locking mechanism will not allow a complete removal of the unit at this stage.

Press on the locking spring (appears in red in Figure 14) on both sides simultaneously, and con-

tinue pulling the unit towards you until it is fully removed.
