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.

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.

Scenario 1

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.

4 Installing Adjustable Guide Rails

5 Installing Floating Nuts (for 4U Devices Only)

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.

1 General View of Cable Connecting Ports

2 Connecting Ground Cables

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.

Directly connecting host ports to the application

server

Scenario 2

Connecting host ports to the application server

through FC switches

Scenario 1

Directly connecting the management network port to

the maintenance terminal

Scenario 2

Connecting the management network port to the

maintenance terminal through an Ethernet switch
