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).

3.3CE Conformity
10 Operating Manual
3.3. CE Conformity
The device complies with the requirements of EC directives 2004/108/EEC regarding
“Electromagnetic Compatibility“ and 2006/95/EEC “Low-Voltage Directive“. This is indicated
by the CE certificate label (CE = Communauté Européenne) on the back of the device.
3.4. RFI Suppression
All other equipment which is connected to this product must also have radio noise suppression in
accordance with EC directive 89/336/EEC.
Products which meet this requirement are accompanied by a certificate to that effect issued by the
manufacturer and/or bear the CE mark. Products which do not meet this requirement may be operated
only with the special permission of the German Federal Approvals Office for Telecommunications (BZT).
This is "Class A" equipment. This equipment may cause harmful inter- ference in residential areas.
In this case, the user may be required to take appropriate measures and bear the costs resulting
from these measures.
3.5. Notes on Mounting the Rack
●For safety reasons, at least two people are required to install the storage subsystem because of its
weight and size.
●When connecting and disconnecting the cables, observe the notes in the operating manual for
your system and the chapter “Important notes”in the technical manual for the relevant rack.
●Ensure that the anti-tilt bracket is correctly mounted when you set up the rack.
●For safety reasons, no more than one unit may be pulled out of the rack at any one time during
installation and maintenance work.
●If more than one unit is pulled out at any one time, the rack may tip over.
●The rack must be connected to the mains by an authorized specialist (electrician).

3.6. Environmental Protection
Notes on packaging
Do not throw away the packaging as you may need it for future transport. If possible, devices should be
transported in their original packaging.
This packaging information doesn’t apply to the Japanese market.
Notes on labeling plastic housing parts
Avoid sticking your own labels on plastic housing parts whenever possible, as this makes recycling more
difficult.
Take-back, recycling and disposal
The device must not be disposed of together with regular household refuse. This device is
labeled according to European directive 2002/96/EC on Waste from Electrical and Electronic
Equipment - WEEE).
This directive sets the framework for EC-wide take-back and recycling of used devices. To return
your device, please use the return or collection systems available to you.

ATTENTION!
When handling systems and boards, make sure you observe the safety information in the chapter
“Important Notes” on page 7.
4.1. Preparation
To replace components which are not hot-pluggable, proceed as follows:
Shut down the server connected to the storage subsystem; wait until the server and the storage
subsystem are switched off.
Unplug the two power plugs of the storage subsystem from the mains.
Disconnect the SAS cable(s) from the SAS expander module (after keeping a record for the
correct reconnection).
