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.
Note the following when installing the ETERNUS DX Disk storage system in the rack.
4.1.1
Placement in the Rack
Enclosures are installed in the following order (from bottom to top). Tall racks (such as the
40U/36U) will have a higher center of gravity and anti-tipping measures are required.
Table 4.1
Enclosure installation order
Install drive enclosures in order of DE-IDs (drive enclosure numbers).
Order
Enclosure
Size (height)
1
Power distribution unit (PDU)
1U/2U
2
Controller enclosure (CE)
2U
3
Drive enclosure (DE)
2U
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.
