Prerequisites:

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 two installation options shown in the table below, and consider 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 and avoid blocking the air flow.

  • The FRUs, as well as high-speed and MNG cables, must be extracted for replacement as part of the switch service. Consider this when planning the switch installation.|

The following steps details the installation process:

  1. Install both rack rails (A) by inserting their pins to the designated key holes in the rack, and aligning them in an angular position.

  2. Secure the assembly by gently pushing the rails' pins through the slider key holes, until locking occurs.

To mount the system into the rack:

Warning

At least two people and server lift are required to safely mount the system in the rack.

While the server lift is supporting the system’s weight, perform the following steps::

  1. Slide the system into the rails, until the black cubes which adjacent to the front panel, touching the rack.

  2. Tighten the captive screws on both sides to fully secure the system to the rack's posts.

Once the system is fully secured in the rack, install the two Black Cubes (C) on the back of the rack rail as shown, and tighen the two captive screws:

To remove the system from the rack:

  1. Turn off the system and disconnect it from peripherals and from the electrical outlet.

    While server lift is supporting the system’s weight:

  2. Loosen back captive screws and remove Black cubes (C).

  3. Loosen front captive screws and pull the system out.

    Warning

    This is a heavy system. Server lift is required to support the system weight safely.

  4. Release the rack rails and system rails:

    To release the rack rails, press the locking buttons on both sides and slightly push the rail towards the inside of the cabinet until the the rail pins removed out from the rack post holes.
