1.1Documentation Overview
4 Operating Manual
1. Preface
The storage subsystem is a passive system that can be directly attached for data management or for
expanding the hard disk capacity of connected servers.
With 2 height units (HU), the storage subsystem satisfies the requirements of both compactness and
maximum hard disk capacity in 19-inch rack infrastructures.

2. Procedure
ATTENTION!
The activities described in this manual should only be performed by engineers, service personnel or
technical specialists.
First of all please familiarize yourself with the safety instructions in the chapter “Important Notes” on
page 7.
Make sure that all the manuals you need are available, printing out the PDF files if necessary. You
will definitely need the operating manual for the storage subsystem.
Shut down the server connected to the storage subsystem correctly (see the operating manual for
the relevant server).
Pull out the power plugs of your storage subsystem and – if necessary – also disconnect the cables
of the expander module as described in the chapter “Replacing Components” on page 12.
Replace the defective component as described in the relevant chapter.
If necessary, reconnect the cables of the SAS expander module to the storage subsystem.
Plug the power plugs into the grounded power outlets.

3. Important Notes
3.1. Notes on Safety
This chapter provides safety instructions which you must observe when handling your storage subsystem.
The device complies with the relevant safety regulations for data processing equipment.
The following safety instructions can also be found in the manual entitled “Safety notes and other
important information”. Please also read the notes in the operating manual for the attached system.
If you have any questions on setting up and operating the device in your particular environment, please
contact your sales outlet or one of our Service Desks.
ATTENTION!
● The activities described in this manual may only be performed by specialist technical personnel.
Equipment repairs must only be performed by service staff. Any unauthorized opening or improper
repairs could endanger the user (through electric shock, energy hazard, fire hazard) or damage
the equipment. Please note that any unauthorized opening of the device will result in the
invalidation of the warranty and exclusion from all liability.
● Transport the device only in its original packaging or in packaging which protects it from knocks
and jolts.
● If the device is brought in from a cold environment, condensation may form both inside and on the
outside of the machine. Before operating the device, wait until it is dry and has reached
approximately the same temperature as the installation site. Failure to observe these guidelines
can lead to material damage of the device.
● Check that the rated voltage specified on the device's ID plate is the same as the local mains
voltage.
● Only connect the device to a properly grounded wall outlet (the device is fitted with a tested and
approved power cable).
3.1Notes on Safety
8 Operating Manual
ATTENTION!
● Make sure that the sockets on the device and the power points used are freely accessible.
● Switching off the devices does not disconnect them from the mains. To completely disconnect it
from the mains voltage, you must remove the power plugs from the power outlet.
● Before opening the device pull out the power plug first.
● Route the cables in such a way that they do not form a potential hazard (tripping) and cannot be
damaged. When connecting a device, refer to the relevant notes in the appropriate operating
manual.
● Do not connect or disconnect any data transmission cables during a thunderstorm (lightning
hazard).
● Systems which comprise a number of cabinets must use a separate fused socket for each cabinet.
● Always connect the server and the directly connected external storage subsystems to the same
power supply distributor. Otherwise you run the risk of losing data if, for example, the central unit is
still running but the storage subsystem has failed during a power cut.
● Make sure that no objects (such as bracelets or paper clips) fall into or liquids spill into the device
(risk of electric shock or short circuit).
● In emergencies (e.g. damaged casing, control elements or cable, penetration of liquids or foreign
bodies), unplug the device from the mains immediately, and contact your customer service center.
● Note that proper operation of the system (in accordance with IEC 60950-1/EN 60950-1) is only
guaranteed if slot covers are installed in all vacant slots and/or dummies in all vacant bays and the
housing cover is fitted (cooling, fire protection, RFI suppression).

3.2. ESD Label
Components which can be damaged by electrostatic discharge (ESDs, electro- static-sensitive devices)
may have the following label:
Figure 1: ESD label
When handling modules with ESDs, it is essential that you observe the following guidelines:
You must electrostatically discharge yourself (e.g. by touching a grounded
object) before handling modules with ESDs.
Any devices or tools that are used must be free of electrostatic charge.
Pull out the power plug before installing or uninstalling modules containing
electrostatic-sensitive components.
Touch modules containing electrostatic-sensitive components only at the edges.
Do not touch any connectors or conduction paths on a module containing electrostatic-sensitive
components.
While installing modules, wear a suitable grounding strap that connects you to the system unit.
Place all the components on a pad which is free of electrostatic charge.
For a detailed description of how to handle ESD-module components, see the relevant
European or international standards (EN 61340-5-1, ANSI/ESD S20.20).
