Use the following templates and instructions to identify the proper locations for
inserting M5 screws when mounting the support rails and DS5100 and DS5300 to a
rack cabinet. The locations for the M5 screws are highlighted in the templates.
Hold the appropriate template up to each side of the rack cabinet at the 4–U
section where you will install the DS5100 and DS5300. 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 DS5100 and DS5300 to the front and rear of the
cabinet.
The DS5100 and DS5300 is 4 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.
