Preparing the Installation Site

It is your responsibility to prepare the site prior to installing the rack. If available, refer to the site planning guide for any server or equipment you plan to install in the rack for additional site preparation requirements.

Prior to installing the rack, perform the following tasks:

  1. Thoroughly clean and vacuum the area in preparation of the installation.

  2. Note any problems or peculiarities at the site that require special equipment.

  3. Verify that the installation site flooring has a high enough strength rating to withstand the combined weight of the rack and any installed equipment.

  4. Install all necessary electrical equipment and ensure that sufficient power is provided.

    Refer to the Sun Rack II Power Distribution Units User’s Guide for the power requirements of the Sun Rack II power distribution units.

  5. Ensure that the installation site provides adequate air conditioning.

  6. Operate the air conditioning system for 48 hours to bring the room to the appropriate temperature.

Mounting Holes and Cable Routing Floor Cutout

You can permanently mount the rack to the installation site floor using the same mounting brackets that secured the rack to the shipping pallet. If you plan on stabilizing the rack using these mounting brackets, prepare the installation site by drilling four holes into the floor. See Bottom View of Sun Rack II 1042 Showing Mounting Hole and Floor Cutout Dimensions for the Sun Rack II 1042 hole spacing locations and Bottom View of Sun Rack II 1242 Showing Mounting Hole and Floor Cutout Dimensions for the Sun Rack II 1242 hole spacing locations.

If you will route data or PDU power cords down through the bottom of the rack, you need to cut out a hole in your installation site’s floor. Cut out a rectangular hole below the rear portion of the rack, safely between the two rear casters and behind the rear RETMA rails. See Bottom View of Sun Rack II 1042 Showing Feet and Castor Dimensions and Bottom View of Sun Rack II 1242 Showing Feet and Castor Dimensions for the location and dimensions of this floor cutout.


Note - The Sun Rack II cabinet is secured to its heavy-duty shipping pallet with six mounting brackets. Use only four brackets (two front and two rear) to stabilize the rack securely to the installation site floor. See Stabilize the Rack With the Mounting Brackets for the mounting instructions.



Caution

Caution - Avoid creating a hole where the rack’s castors or leveling feet brackets will be. See Leveling Feet and Castor Dimensions for the location of these parts.
