Rack mounting template

Attention: Duplicate copies of the rack mounting templates are provided in

Appendix B, “Rack mounting template,” on page 121. If you want to tear out the
templates from this document for easier use, use the copies in Appendix B, “Rack
mounting template,” on page 121 rather than the copies provided in this section.
Use the following templates (Figure 9 on page 21 and Figure 10 on page 22) to
identify the proper locations for inserting M6 screws when mounting the support
rails and DS4100 to a rack cabinet. The locations for the M6 screws are highlighted
in the templates.
The DS4100 is 3 U high. Align the template with the rack at a U boundary. U
boundaries are shown as horizontal dashed lines in the rack mounting templates.

Note: The mounting holes that are shown in the following templates are square.

The holes in your rack cabinet might be round, square, or threaded.
