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, 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.

Preparations for Installation

1 Verifying Installation Tools 2 Verifying Circuit Breakers

3 Verifying Materials

The installation tools needed to

prepare include:

Phillips screwdriver (M3-M6)

Flat-head screwdriver (M3-M6)

Diagonal pliers

Floating nut mounting bar

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 (2 U) Adjustable guide rails

Front panel (2 U)

Multi-mode optical fiber

Network cable

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.

Installing Devices

1 Planning Device Installation Positions

2 Removing Filler Panels

3 Determining Device Installation Positions with Installation Templates

Before the planning, you need to calculate the required cabinet space, as listed in the following table.

Installation position of a 2 U device (shown as the shade)

Installation Item Controller enclosure Disk enclosure

Required Space 2 U 2 U (for the 2U SAS disk enclosure)

Remarks: The total of the required cabinet space can be calculated through the following formula:

2 U + 2 U x (number of 2 U disk enclosures)

Figure 1 Figure 2

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 the floating nut mounting bar is

unavailable, 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 cause injuries.

Based on the calculated cabinet space, you can plan the installation positions of the devices for the convenience

of the installation and expansion.

4 Installing Adjustable Guide Rails

5 Installing the Controller Enclosure

Installing adjustable guide rails for a 2 U 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.

To avoid device damage, do not directly

pile up the devices but install the devices

onto the guide rails.

6 Installing the Disk Enclosure

Install the disk enclosure onto the adjustable guide rails in the method of installing the controller enclosure.

7 Installing Floating Nuts

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.

8 Installing Filler Panels

If you do not have a floating nut mounting 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 injure the hands or storage devices.

Connecting Cables

1 General View of Cable Connecting Ports

2 Connecting Ground Cables

The figure below shows the general view of cable connecting ports (using the AC controller enclosure

configured with 10 Gb TOE host ports as an example).

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.

3 Connecting Disk Enclosures to the Controller Enclosure

All EXP expansion ports on the storage devices only connect to the PRI expansion ports.

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.

Each 6 Gb SAS expansion port on the controller enclosure can be connected to a maximum of three

disk enclosures, each of which supports up to 25 disks.

The bend radius of the mini SAS cable should be larger than 150 mm (5.91 inches).

If the controller enclosure is connected to one or two disk enclosures: Expansion module on

controller A must connect to expansion module A on each disk enclosure. Expansion module on

controller B must connect to expansion module B on each disk enclosure.

If the controller enclosure is connected to three disk enclosures: The third disk enclosure is directly

connected to the first or second disk enclosure.

4 Connecting the Storage System to a Network

5 Connecting the Serial Port to the Maintenance Terminal

The controller enclosure is connected to the application server through FC host ports (8 Gbit/s), TOE

host ports (10 Gbit/s), or IB host ports (40 Gbit/s).

A management channel can be set up by connecting the management network port on the controller

enclosure to the network port on the maintenance terminal using a network cable so that the

maintenance terminal can manage and maintain the storage device.

For details about each port and the cable connected to it, see the OceanStor Dorado2100 G2 Storage

System Installation Guide.

After connecting the serial port to the maintenance terminal using a serial cable, you can manage

and maintain the storage system through the serial port.

Normally, the serial cable is an RJ-45 to DB-9 serial cable.

For details on how to connect a serial port, see the OceanStor Dorado2100 G2 Storage System Installation

Guide.

When connecting the DC power cables, ensure that the black cable leading from the anode of the DC

power source connects to the RTN (+) terminal and that the blue cable leading from the cathode of the DC

power source connects to the NEG (-) terminal.

6 Connecting Power Cables

Scenario 1

Connecting AC power cables

Complete view of the connected AC power cables

The AC device is allowed to connect to AC power supplies only, and the DC device is allowed to

connect to DC power supplies only.

The AC power modules and DC power modules of the storage system can connect to two routes of

power supplies. To ensure the high availability of the storage system and avoid unexpected power-

down of the storage system caused by the failure of the power supplies, connect the storage system

to two routes of power supplies.
