Installing the support rails
Important: Duplicate copies of the rack mounting templates are provided in
Appendix B, “Rack mounting templates,” on page 171. If you want to
tear out the templates from this document, use the copies in
Appendix B, “Rack mounting templates,” on page 171.
Use the following templates (Figure 12 and Figure 13 on page 34) to identify the
proper locations for inserting M5 screws when mounting the support rails and
DS3950 storage subsystem to a rack cabinet. The locations for the M5 screws are
highlighted in the templates.
Hold the applicable template up to each side of the rack cabinet at the 3U section
where you will install the DS3950. U boundaries are shown as horizontal dashed
lines in the rack mounting templates. The highlighted squares on each side of the
template mark the positions where you will thread the M5 screws that secure the
rails and the DS3950 to the front and rear of the cabinet.
Note: The mounting holes that are shown in the following templates are square.
The holes in your rack might be round, square, or threaded.
