To determine where to install the slide assemblies in the rack, perform the following steps: 1. Place the front of the template on the vertical rails at the front of the rack where you want to install the system. The printing on the template identifies the side facing outwards as the template front. 2. Position the bottom of the template where the system's lower edge will be located. 3. Mark the rack's front vertical rails with a felt-tip marker or place masking tape where the system's upper and lower edges will be located (see Figure 1-7). Make a mark or place tape on the vertical rails next to the template's V-shaped notches. 1-8 Dell PowerEdge 6x50 Systems Rack Installation Guide
