Chapter 4 Rack and Optional Product Installation
This chapter explains the requirements for installation of racks and the optional products for an
ETERNUS DX Disk storage system.
4.1 Rack Installation Requirements
This section explains the requirements for installing the ETERNUS DX Disk storage system in a
19-inch rack.
Enclosures are installed in the following order (from bottom to top).
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.
Table 4.1 Enclosure installation order
Order Enclosure Size (height)
1 Power distribution unit (PDU) 1U/2U
2 Controller enclosure (CE) 2U
3 Drive enclosure (DE) 2U
Install the controller enclosure and drive enclosure in the same rack.
• When determining the rack-mounting layout, consider the placement of
each enclosure and the power distribution unit in the rack and the length
of each cable. For example, if the ETERNUS DX Disk storage system is
installed at the top of a 1800mm rack, the surplus length of the power
cord at the bottom of a rack should be about 2m.
• 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.
