Installing the SAN Volume Controller 2145-8A4 in a rack

After installing the support rails, you can install the SAN Volume Controller 2145-8A4 in the rack.

1. On each side of the node, reposition the rail that is attached to the side of the node. By doing this, the node is more secure if the rack is moved. Remove the larger screw  1  shown in Figure 1. Remove and save screw  2 . Loosen screws  3  and  4 . Slide the rail toward the back of the node and insert the screw that you saved into the position where the large screw  1  had been located. Tighten the three screws  2 ,  3 , and  4 .

2. Align the node on the slide rails and push the node fully into the rack. Secure the node to the front mounting flanges by tightening the captive thumbscrews  1  shown in Figure 2.
   Note: Leave the shipping brackets  2  attached to the slide rails unless the shipping brackets impede the node from sliding fully into the rack. If you need to remove the shipping brackets, continue with the next step.

3. Optionally, press on the release tab  1  that is indicated on the shipping bracket (shown in Figure 3), and remove the shipping bracket from the slide rail. Repeat this step for the other shipping bracket. Store the shipping brackets for future use.
   Note: You must reinstall the shipping brackets on the slide rails before you transport the rack with the node installed. To reinstall the shipping brackets, reverse this step.

4. Secure the slide rails to the rack, as shown in Figure 4. Slide the node out of the rack 15 cm (6 in) and insert the M6 screws in each slide rail. Push the node back into place.

   If you need to transport the rack to another location with the node installed, ensure that the rails are fully extended to the rear of the rack and that the shipping brackets are installed.

5. Secure the node to the front mounting flanges by tightening the captive thumbscrews  1  shown in Figure 2.
6. Repeat this procedure for each SAN Volume Controller 2145-8A4 node that needs to be installed.
   Tip: If you have available space, leave a 1U space between each node to improve the air circulation in the rack.
