Rack Installation
This chapter describes the procedure for installing the ETERNUS DX Disk storage system in a rack.
Make sure to check the manual that contains the safety precautions before installing the ETERNUS DX Disk
storage system in a rack. Also refer to the manual provided with racks.
CAUTION
• If the storage system is installed at the bottom of a rack, a space for the surplus of cables may not be
available in some racks, preventing the storage system from being pulled out when maintenance work is
required. In this case, secure a space of 1U or more at the bottom when installing the storage system.
• To install an enclosure, power distribution units, power synchronized units, and UPS units in a single rack,
mount the devices in the following order (from bottom to top).
Drive enclosures must also be installed in order of DE-ID (DE_No. label).

Do
• Make sure to wear a wrist strap or discharge static electricity by touching the
metal frame of the ETERNUS DX Disk storage system before starting each
operation, as failure to discharge static electricity may cause device failure.
• If components are installed in a way other as described in this section,
damage and/or device failure or electrical shock may occur
• Do not install the ETERNUS DX Disk storage system with cables, such as power
cords, connected.
• The ETERNUS DX Disk storage system contains delicate components, and
should be handled gently. Do not drop or knock the ETERNUS DX Disk storage
system against the rack when installing it. Also, do not knock the other
devices installed in the rack.
• The center of gravity must be taken into consideration to prevent a rack from
toppling over. Enclosures should generally be installed from bottom to top to
lower the center of gravity and to ensure the safe use of racks.
