How to unpack the small disk enclosure
1. Examine the packaging for crushes, cuts, water damage or any other evidence of mishandling during
transit. If you suspect that damage has happened, photograph the packaging before you open it: this is
for possible future reference.
2. The following figure shows the sequence for how to unpack.

How to plan and configure your installation
You should become familiar with the configuration requirements of your small disk enclosure system
before you begin installation. Refer to the section on system configurations for more information.
Requirements for installation of the racks
You can install the small disk enclosure in an industry standard 19 inch cabinet that is capable of holding
such enclosures.
• Minimum depth: 707mm (27.83 inches) from rack posts to maximum extremity of enclosure (excludes
rear cabling).
• Weight: up to 29kg (64lb), dependent upon configuration, per enclosure.
• There must be a minimum gap of 25mm (1 inch) clearance between the rack cover and front of drawer;
and 50mm (2 inches) rear clearance between the rear of the drawer and rear of the rack. This is to make
sure there is correct air flow around the enclosure.
• The rack should cause a maximum back pressure of 5 pascals (0.5mm water gauge).
Rack mount rail kit
Various sets of rack mounting rails are available for use in 19 inch rack cabinets. These rails have been
designed and tested for the maximum enclosure weight and to make sure that multiple enclosures may
be installed without loss of space within the rack. Use of other mounting hardware may cause some loss
of rack space.
