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/m2, and the height between the floor and the ceiling must be more than

Storage Enclosure Quick Start Guide
8
2.7 m. The loading capability of the rack can be computed in 10 kg/U, e.g., for a
4U chassis, the required loading capability of the rack is 40 kg.
Ensure adequate air ventilation of the rack.
Close all the doors and windows to prevent the dust or use a dust-filtering
ventilation device. The dust particulate (≥5μm) must be less than 18,000
particulate / (dm)³.
In a conditions of non-working status of the device, the horizontal and vertical
vibration acceleration value of the floor surface of equipment room must be
lower than 0.5m/S².
The rack or surface on which the device is installed must be properly grounded,
and ensure that each device is grounded as well. The resistance between the
device casing and the ground must be less than 4Ω.
2.2 Installation and Initial Power-on
The device shall be placed on the fixed flat surface. Tilting surface is not allowed.
You can use the standard plate in the industrial cabinet or use the guide rail (not
provided) to install the device to the rack. It is recommended to use the bolts to
fix the device to the rack through the mounting screw holes on the rack.
Connect all the power cords of the device to the power socket and wait for 12
hours before starting up. The temperature of the device and the equipment
room must be consistent to prevent the damage caused by a huge temperature
difference.
If the device has been transported and stored for more than 10 days; perform
the previous operation and then start up and run the device for 30 minutes
without the hard disks. And then you shut down the device, insert the hard disks
and start the device again.
2.3 Installation Notes
The device is a high-precision equipment. Please keep stable and gentle when
moving it.
Installation and running environment must meet standards. Take regular
investigations and records for the equipment room, or apply a remote
monitoring for the working status of the device.
Do not unplug the power cord when the device is running.
In case of alarm beeper produced during the system running, please take
immediate check and solution.
2.4 Power on/off
Step 1 If the storage enclosure is configured with redundant power supplies, please
make all connections of the power.

Please check the following hardware connection
Power cord connection: connect the power cord to 110V~220VAC power supply.
Connect the SAS cable to storage system. The default interface is UP1.
before installing device, please wear a wrist strap and ensure it is correctly grounded.
3.2.2 Install HDD
Select HDD Model
It is recommended to adopt the certificated professional HDD models so as to ensure
the stable running of the system and the reliable data storage. It is highly
recommended to purchase the enterprise-class hard disks, e.g., Seagate
Constellation™ ES, Western Digital WD RE3 and WD RE4 series hard disk.
The use of non-enterprise hard disks for establishing RAID may cause instability of
the system running and thus lead to data damage. In case of hard disk failure, please
replace it with the functioning one immediately so as to prevent the data loss or
performance effect. Please refer to the List of Compatible HDD Models of our
company for the recommended HDD models.
In order to avoid damages during transportation, it is recommended to package and
transport the hard disks separately with the chassis of network storage system.
Install HDD
Follow the steps below to install HDDs. We use 24 slots device as an example to
describe the following operations.
Step 1 Use the panel key to unlock the front panel and then pull out the front panel.
Step 2 Press the spring lock of the HDD on the left, draw the handle and then pull out
the HDD bracket from the chassis along the guide apparatus.
Step 3 Use four screws to secure the HDD (with the PCB side downward) to the
bracket. In order to ensure the HDD pin holds the line with the rear of the plate,
mount screws to the specific screw hole as shown.
Step 4 Insert the HDD bracket (with the PCB side towards the left of the chassis) to
the chassis and push it along the guide apparatus to the bottom. Then, press
the securing handle to ensure the bracket has been seated into position and
lock it.
Step 5 Repeat the operating steps above till all HDDs have been installed.

Figure 3-7 HDD Installation Diagram
Precautions during HDD Installation
When you plug or unplug the hard disks, please take the following precautions:
After you have plugged the hard disk to its mounting bracket, please use the
provided screws to fix the four edges of the mounting bracket.
Make sure the HDD mounting bracket is steadily plugged to the chassis along the
slot.
When you unplug the hard disk, unplug it about 3cm away from the chassis and
then make it stay about 30 seconds on the slot guide before totally unplug it
from the chassis. Since the discs of the hard disk are still spinning at a high speed
just after powering off, unplugging the hard disk immediately will damage the
discs.
The system supports disk hot swapping, yet the data storage safety is not
ensured.

Storage Enclosure Quick Start Guide
16
Please avoid frequent plugging/unplugging of the hard disks during the system
running so as to maintain long service life of the hard disks.
Take regular check and examine of the working status of the hard disks every two
months, or configure the system with auto check and examine task.
Please avoid unplugging a hard disk when it is writing/reading data so as to prevent
data loss.
