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.
4.1.1
Placement in the Rack
Note the following when installing the ETERNUS DX Disk storage system 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.
•
Enclosures are installed in the following order (from bottom to top).

Install drive enclosures in order of DE-IDs (drive enclosure numbers)
.
•
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.
•
If drive enclosures are to be added in the future, securing sufficient space for power distribution units in
the bottom of the rack is recommended.
