Chapter 2 Working Environment and
Installation
Devices described in this manual should be installed in the standard equipment
room.
2.1 Environment of Equipment Room
2.1.1 Power Supply System
The storage enclosure is sensitive to the change of a voltage, and an excessively high
or low voltage, or a sudden change of the voltage may delete the data in the memory
or even cause the damage of the components. To avoid of such damage, you must
ensure the power supply is stable and grounded. You are recommended to use the
UPS, or the multiple power supply if permitted.
Requirements:

The voltage should be in the range of 110V to 220V (allowed range is between
-4% to +4%), and the change must be in the range of 110V to 220V(allowed
range is between -15% to +15%); Frequency: 50~60Hz+/-0.5Hz;

Make correct neutral line and GND line connections, and the voltage between
them must be less than 1V.

Grounding for AC power supply system: ensure the GND line is properly
connected. The grounding for the chassis is recommended.

Grounding for DC power supply system: the chassis must be properly grounded.

Connect all power cords before applying power to the redundant power supply
module.

The storage system supports management for some UPS models.
2.1.2 Working Environment Control
The over-high or over-low temperature and other unsatisfying installation and
running environment factors may cause failures of the chip and mechanical
components of the device, and thus they affect the stable and reliable running of the
device as well as the data safety on the disks. Please follow the measurements shown
below to take proper measurements:

Use an air conditioner to control the temperature and the humidity at least 2 or
3 days before installing the device.

The floor in the equipment room must be capable of loading more than
600kg/m

, and the height between the floor and the ceiling must be more than
