This chapter explains the rack installation specifications of the ETERNUS DX.
2.1

Rack Installation Requirements

This section explains the requirements for installing the ETERNUS DX in a 19-inch rack.
2.1.1

Placement in the Rack

Note the following when installing the ETERNUS DX 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).

*1: This is an Uninterruptible Power Supply.
*2: This is an optional product for only the ETERNUS DX.
When determining the rack-mounting layout of each enclosure and power distribution unit, consider the
•
length of each cable. For example, if the ETERNUS DX is installed at the top of a 2,000mm rack and a 4m
power cord is used, 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.
