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.Important Notes

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).
