Installation overview

Statement 4:
≥18 kg (39.7 lb) ≥32 kg (70.5 lb) ≥55 kg (121.2 lb)
CAUTION:
Use safe practices when lifting.
Attention: A fully configured DS5020 weighs up to 40 kg (88 lb).At least two
other people should help you lift the DS5020 from the shipping box. If desired, open
the sides of the shipping box and remove the CRUs from the DS5020 before you lift
it from the shipping box in order to lighten the storage subsystem. See “Removing
the CRUs” on page 36.
The following steps summarize the DS5020 installation process. Each step below is
detailed in this chapter or next two chapters, Chapter 3, “Cabling the storage
subsystem,” on page 45 and Chapter 4, “Operating the storage subsystem,” on
page 93.
1. Review the preparation guidelines. See “Preparing for installation” on page 29.
2. Prepare the installation site. See “Preparing the site” on page 31.
3. Prepare the rack cabinet. See “Preparing the rack cabinet” on page 32.
4. Fold down and open the sides of the shipping box. Without removing the
DS5020 from box, you can remove the DS5020 rack mounting rails and
hardware from the box. The DS5020 rack mounting rails and hardware are
placed on the bottom of the shipping box (under the DS5020 storage
subsystem). Install the support rails in the rack cabinet. See “Installing the
support rails” on page 32.
