DSDA iSCSI Disk Array Series Precautions | en 3
1 Precautions
– The system is heavy even without disks installed. At least two people are required to
install the system.
– The rack cabinet into which this system will be installed must support overcurrent
protection and must not be overloaded by the modules installed. Other requirements,
such as ventilation airflow, rack stabilizing features, electrical earth, and electrical
distribution, must comply with the technical specifications listed in Section 8 Technical
Data, page 31 and in the documentation that came with this product.
– All systems must be mounted with and supported by the rails provided and secured in
position by the four screws in the front side flanges. In no instance is a system to be
mounted by the front side flanges only as this will result in the deforming of the systems
chassis causing unacceptably high pressures and/or torques to be applied to internal
components resulting in various failure modes.
– System Integrators should ensure that any integrated storage solution that includes this
product has been tested and proved to meet government regulations and codes for
subjects including safety, fire, and electrical.
– Make sure you have a soft, clean surface to place your system before working on it.
Placing the system on a rough surface during servicing may damage the chassis finish.
– Do not remove any module or component item from its anti-static bag until you are ready
to install it. Pick up and hold modules by their edges or canister. Avoid touching PCBs
and connector pins.
– Observe all standard ESD prevention methods, e.g., wear an anti-static wristband to
prevent static electricity from damaging the electric components.
– When replacing components insert them as gently as possible while assuring full
engagement. Vibration or shock can damage hard drives in the affected unit or other
units in the rack. Hard drives are very sensitive to shock and vibration, especially while in
operation and should always be handled very carefully.
– After all equipment is installed in a rack dress the power and data cables such that power
cables are not resting against data (SCSI, IP, RS-232) cables.

3 Unpacking and Installing the Hardware
NOTICE!
For more detailed information on the hardware installation please refer to the documentation
available on www.boschsecurity.com under Product Catalog > CCTV > IP Video > Disk
Arrays.
WARNING!
The storage system is heavy. Two people are required to lift a system.
CAUTION!
Only use the rail kit supplied with the system. Using a different rail kit can cause injury to you
or damage to your system.
1. Unpack your system by opening the packing box and lifting the outer shipping box off the
pallet.
2. Install the appropriate rack mount for your installation and system using the Rack
Installation flyer in the rail kit box for reference.
3. Install the appropriate rack mount for any disk shelves that will be connected to the
system
4. With two people, lift the system into the rack or system cabinet, and secure it to the rack
uprights. The system weighs slightly over 30 kg (67 lb) and requires one person at the
end of the system to guide it into the rail ends.
5. For installation and wiring of additional disk shelves, see Section 6 Adding Storage,
page 17.
6. Connect the power cords, making sure that the power supplies are connected to
separate AC power sources. This ensures redundant power sources.
Make sure to set the power cable retention clips properly.
Ensure that power supply LEDs are lit.

5 Configuration through the Web Interface
NOTICE!
Do not use the S5B50 management software StoreVault Manager for the configuration. The
DSA series come with a dedicated Bosch standardized system layout. StoreVault Manager is
not compatible with the Bosch layout.
Follow these steps to configure each system. This procedure is nearly identical for all three
types of storage systems.
1. Turn on the system.
DSA-S5B50: The power button is located on the front side on the left-hand side.
DSA-N2B20 / DSA- N2B50 / additional disk shelves: There is a power switch on each
power supply unit (right- and left-hand side) on the rear side of the device.
If there are additional disk shelves installed, first power on the base unit, then power on
the expansion units.
NOTICE!
It can take a few seconds until the LEDs on your system power supplies light up.
NOTICE!
The Java Runtime Environment must be installed on your computer in order to use the Web
interface. Always use the most recent version.
5.1 Configuration of the Network Settings and Access to the Interface
All systems are delivered with a default IP address configuration of 10.10.10.10, netmask
255.0.0.0. In order to connect to the system, you need to configure a network interface on
your computer to use the same network.

2. Select from the Control Panel of your computer Network Connections, Properties.
Here, configure your network interface to use IP address 10.10.10.9 with Subnet mask
255.0.0.0.
Example screen:
NOTICE!
The IP address 10.10.10.9 is an example. The IP addresses 10.10.10.10 and 10.10.10.11 are
the default IP addresses for the storage system and cannot be used otherwise.
3. Connect your computer directly to the network port labeled e0a on the storage system,
using a crossover cable.
Alternatively, connect your computer to the network the storage system is connected to.
4. Open a Web browser and enter http://10.10.10.10/na_admin.
You will be asked to log in.
