1. Make sure that the rack cabinet has already been installed.
2. Make sure that a stabilizer has been correctly attached to the bottom front of
the rack to prevent the rack from tipping forward while the DS5020 is being
installed.
Refer to the installation and service guide, or equivalent, for the rack as
required.
3. Locate the two support rails, eight of the twelve M5 screws, and eight washers
that are supplied with the DS5020.
Note: The M5 screws and washers might already be attached to the support
rails. If so, remove them from the support rails.
4. The rack-mounted unit is three EIA units high. Decide accordingly where you
are going to install the support rails.
Important: Duplicate copies of the rack mounting templates are provided in
Appendix B, “Rack mounting templates,” on page 167. If you want
to tear out the templates from this document, use the copies in
Appendix B, “Rack mounting templates,” on page 167. Use the
preceding templates (Figure 13 on page 33 and Figure14 on page
34) to identify the proper locations for inserting M5 screws when
mounting the support rails and DS5020 storage subsystem to a
rack cabinet. The locations for the M5 screws are highlighted in
the templates.
Note the following considerations before you choose where to install the rails:
vIf you are installing the DS5020 into an empty rack, install it into the lowest
available position so that the rack does not become unstable.
vIf you are installing more than one DS5020 in the rack, start at the lowest
available position, and work upward.
vIf applicable, allow for possible later installation of other units.
vIf necessary, remove the rack power distribution unit before you install the
support rails.
vFor procedures and more information, refer to the installation and service
guide, or equivalent, for the rack.
