Do not operate devices or handle cables on a stormy day.
To avoid injuries to eyes, do not stare into the optical outlets.
To avoid data loss, do not insert or remove disks, controllers, expansion modules, or cables during power-on.
To avoid device damage, ensure that the devices are properly grounded before power-on.

Safety Information
To avoid personal injuries, it is recommended to carry one fully configured controller enclosure or disk enclosure
by three persons.
Before handling devices, wear ESD clothes, ESD gloves or ESD wrist strap, and take off conductive objects such
as ornaments and watches.
Do not wear an ESD wrist strap during the power-on process to avoid electric shocks.

Diagonal pliers
Floating nut mount bar
Multi-mode optical fibre

Network cable Installation template (for 4U devices) Installation template (for 2U devices)
The above table only includes part of the materials to be used during the installation. For information about all the
materials, see the Packing List.
To prevent other devices connected to the circuit breakers from being
incorrectly powered off due to a power supply failure of the storage device,
you are advised to ensure that the electric current of the circuit breakers of the
external power supplies to which the storage device is connected complies
with the following specifications:
Controller enclosure:
16 A (for AC power supplies)
Disk enclosure:
16 A (for AC power supplies)

Installing Devices
Before the planning, you need to calculate the required cabinet space, as listed in the following table.
Installation Item Controller enclosure Disk enclosure Cable rack
Required Space 4U 2U (for the 2U SSD disk enclosure) 2U
Remarks: The total of the required cabinet space can be calculated through the following formula: 4U + 2U
x (number of 2U disk enclosures) + 2U.
Based on the calculated cabinet space, you can plan the installation positions of the controller enclosure, disk
enclosures, and cable rack for the convenience of the installation and expansion.
If the planned device installation positions
are occupied by filler panels, remove them in
the method shown in Figure 1.
After removing the filler panels, remove
floating nuts in the method shown in Figure 2.
If you do not have a floating nut mount bar,
you can use a flat-head screwdriver instead.
When using a flat-head screwdriver to
remove the floating nuts, handle it gently;
otherwise, the flat-head screwdriver may skid,
and thus injure the hands or storage devices.

Installing adjustable guide rails for a 4U device Scenario 2
Installing adjustable guide rails for a 2U device
The length of the adjustable guide rail ranges from 600 mm (23.64 inches) to 900 mm (35.46 inches), and
it can be installed in the cabinet with a depth from 800 mm (31.50 inches) to 1100 mm (43.34 inches).
The adjustable guide rails are initially equipped with positioning pins applicable to square installation holes
only. For round installation holes, replace the positioning pins.
After the left adjustable guide rail is installed, install the right adjustable guide rail in the same method.
If you do not have a floating nut mount bar, you can use a flat-head screwdriver instead. When using a
flat-head screwdriver to install the floating nuts, handle it gently; otherwise, the flat-head screwdriver
may skid, and thus injure the hands or storage devices.
For the 4U device, the adjustable guide rails provide installation holes for only the two lower M6 fixing
screws, and thus, the floating nuts for the two upper M6 fixing screws need to be installed.
For the 2U device, the adjustable guide rails provide installation holes for all the four M6 fixing screws,
and thus, no floating nut needs to be installed.

To avoid device damage, do not directly pile up
the devices but install the devices onto the guide
rails.
Install the disk enclosure onto the adjustable guide rails in the method of installing the controller enclosure.
Scenario 1
Installing the cable rack onto the rear channels
For the cabinet in the depth of 1 m or more, if the controller enclosure rear is more than 70 mm distant
away from the rear channels or if the rear channels are more than 150 mm distant away from the rear
cabinet door, the cable rack must be installed onto the rear channels of the cabinet.
For the cabinet in the depth of 1 m or more, if the controller enclosure rear is 70 mm or less distant away
from the rear channels or if the rear channels are 150 mm or less distant away from the rear cabinet
door, the cable rack must be installed onto the controller enclosure.
For the cabinet in the depth of 800 mm, the cable rack must be installed onto the controller enclosure.

Scenario 2
Installing the cable rack onto the controller enclosure
To ensure good ventilation, it is recommended to cover the unoccupied slots with filler panels. Before
installing the filler panels, check that required floating nuts are installed at the installation holes of the
M6 fixing screws.

Connecting Cables
Scenario 1
Connecting the ground cable to the controller
enclosure
Scenario 2
Connecting the ground cable to the disk enclosure
After connecting one end of the ground cable to the ground terminal of the storage device, connect the other
end of the ground cable to the ground terminal of the cabinet in the same method.
The figure below shows the general view of cable connecting ports.
The interface modules in Slot A0 and B0 of the controller enclosure connect to the disk enclosures only.

3 Connecting Disk Enclosures(SLC)
The expansion ports on the controller enclosure must connect to the PRI expansion ports on the disk
enclosures.
The expansion ports on controller A must connect to the PRI expansion ports on expansion module A of
the disk enclosure; the expansion ports on controller B must connect to the PRI expansion ports on
expansion module B of the disk enclosure.
Only one port on each 6 Gb SAS interface module of a controller enclosure is used to connect to a disk
enclosure.
Use the interface modules that reside in the slots corresponding to controllers A and B to connect to two
expansion modules of the same disk enclosure. For example, if port P0 on slot B1 of a controller
enclosure is connected to disk enclosure 1, then port P0 on slot A1 of the controller enclosure must also
be connected to disk enclosure 1. (One P0 port is connected to expansion module A and the other P0
port is connected to expansion module B.)
The EXP ports on expansion modules of each disk enclosure are idle.

4 Connecting Disk Enclosures(MLC)
The expansion ports on the controller enclosure must connect to the PRI expansion ports on the disk
enclosures.
The expansion ports on controller A must connect to the PRI expansion ports on expansion module A of
the disk enclosure; the expansion ports on controller B must connect to the PRI expansion ports on
expansion module B of the disk enclosure.
Both ports on each 6 Gb SAS interface module of a controller enclosure can be used to connect to disk
enclosures.
Use the interface modules that reside in the slots corresponding to controllers A and B to connect to two
expansion modules of the same disk enclosure. For example, if port P1 on slot B1 of a controller
enclosure is connected to disk enclosure 1, then port P1 on slot A1 of the controller enclosure must also
be connected to disk enclosure 1. (One P1 port is connected to expansion module A and the other P1
port is connected to expansion module B.)
The EXP ports on expansion modules of each disk enclosure are idle.
