2.6 Grounding and Potential Balancing / Erdung und Potenzialausgleich Especially when running a combination of different communications equipment, it is important to establish correct grounding and potential balancing between them − depending on the local grounding measures.

Insbesondere bei gemeinsamer Verwendung verschiedener Kommunikationsgeräte ist es wichtig − abhängig von den örtlichen Erdungsmaßnahmen − auf korrekten Erdungs- und Potenzialausgleich zu achten.

After mounting the systems into the rack, before attaching the connecting cables, and before commissioning, first check the grounding and potential balancing connections to agree with EN50310 and ETSI EN 300 253.

Nach dem Einbau der Systeme in das Gestell sind – vor dem Anschluss der Verbindungskabel und vor der Inbetriebnahme – die Erdungs- und Potenzialausgleichsverbindungen gemäß EN50310 und ETSI EN 300 253 zu über-prüfen.

The grounding must be effective as long as external cables are connected to the equipment.

Die Erdung muss bestehen bleiben, solange Kabel von außen an die Geräte angeschlossen sind.

If a subrack is not installed in a system rack you must ensure that it is properly grounded in some other way (according to ETSI EN 300 253).

Wenn die Baugruppenträger bzw. Einsätze nicht in einem Systemgestell montiert werden, müssen Sie auf andere Weise für geeignete Erdung sorgen (gemäß ETSI EN 300 253).

Grounding or potential balancing points are normally labeled with one of the signs shown below.

Erdungs- oder Potenzialausgleichspunkte sind normalerweise mit einem der nach-folgend dargestellten Zeichen gekennze-zeichnet

Protective earth (PE)

Schutzerde (PE)

Ground (E)

Erde (E)

In both rack and wall mounted applications, the subrack Protective earthing must be assured by connecting a PE cable as depicted in the Cabling Plan document. The PE cable must be connected before each other cable connection, and discon-nected last.

Sowohl bei Gestellmontage als auch bei Wandmontage des Baugruppenträgers muss die Schutzerdung dadurch sichergestellt sein, dass ein Schutzerdungskabel entsprechend dem Kabelführungsplan angeschlossen ist. Das Schutzerdungskabel muss als erste Verbindung (vor jeder anderen) ange-schlossen und als letzte Verbindung getrennt werden.

2.9 Fiber-optic Cables and Connectors / Lichtwellenleiter und optische Steckverbinder

For laser safety remarks, see Chapter 2.10.

Laser-Sicherheitshinweise siehe Kapitel 2.10.

Optical connectors are precision-made components and must be handled accordingly. To ensure faultless functioning, the following points must be observed.

Optische Steckverbindungen sind Präzisionsteile und müssen dementsprechend behandelt werden. Eine einwandfreie Funktion ist nur dann sichergestellt, wenn nachfolgende Punkte berücksichtigt werden.

The minimum bending radius for optical fibers is 30 mm!

Für LWL-Leitungen darf ein Biegeradius von 30 mm nicht unterschritten werden!

Mechanical damage to the surfaces of optical connectors impairs transmission quality by higher attenuation.

Mechanische Beschädigungen der Stirn-flächen von optischen Steckverbindungen erhöhen die Dämpfung und mindern deshalb die Übertragungsqualität.

For this reason, do not expose the con-nectors to impact.

Vermeiden Sie deshalb Stoßbeanspru-chungen der Steckverbinder.

Always fit optical fiber connectors with protective caps to guard them against me-chanical damage and contamination. The protective dust caps should only be removed immediately prior to installation.

Schützen Sie LWL-Steckverbinder grund-sätzlich mit einer Schutzkappe vor mech-anischen Beschädigungen und Verschmutzungen. Die Staubschutzkappe soll erst unmittelbar vor dem Einbau entfernt werden.

Once the protective dust caps have been removed, you must check the surfaces of the optical fiber connectors to ensure that they are clean, and clean them if necessary.

Prüfen Sie nach Entfernen der Staub-schutzkappen die Stirnflächen der LWL- Stecker auf Sauberkeit und reinigen Sie sie gegebenenfalls.

For cleaning, a special optical fiber cleaning tool or a clean, lint-free cellulose cloth or a chamois leather is suitable. Freon TF, isopropyl alcohol (99 %), or white spirit can be used as cleaning fluids.

Zum Reinigen kann ein spezielles LWL- Reinigungswerkzeug oder ein einwandfrei sauberes, fusselfreies Zellstofftuch oder Fensterleder verwendet werden. Als Reinigungsflüssigkeit kann Freon TF, Iso-propylalkohol (99 %) oder Spiritus verwendet werden.

To ensure safe operation of the entire optical path, the laser safety shutdown must be activated, see Chapter 2.10.2.

Für den sicheren Betrieb der ge-samten optischen Strecke muss die Lasersicherheitsabschaltung aktiviert sein, siehe Kapitel 2.10.2.

Commissioning should be performed with fuse protection in the closed system.

Die Inbetriebnahme soll abgesichert im geschlossenen System erfolgen.

To avoid damage to health, you must

observe the regulations regarding protection against radiation from laser devices (EN 60825-1/ IEC 60825-1).

Zur Vermeidung gesundheitlicher Schäden müssen Sie die Vorschriften zur Strahlungssicherheit von Lasereinrichtungen (EN 60825-1 / IEC 60825-1) beachten.

If it cannot be avoided in an exceptional case to apply the hazard level 1M regu-lations (see above), you always must use dedicated laser-protective goggles.

Falls die Gefährdungsklasse 1M im Aus-nahmefall nicht vermieden werden kann (siehe oben), müssen Sie stets eine Laser-Schutzbrille tragen.

2.10.2 Laser Safety Circuit / Lasersicherheitsabschaltung

Under normal operating conditions, the maximum transmit levels of the optical in-terface units stay below the limit values defined in EN 60825-1 / IEC 60825-1, Laser Class 1.

Unter normalen Betriebsbedingungen bleiben die maximalen Übertragungspegel der optischen Anschlussbaugruppen unterhalb der Grenzen, die nach EN 60825-1/ IEC 60825-1, Laser-Klasse 1, erlaubt sind.

However, all optical transmitters (except at the Ethernet interfaces) are fitted with automatic laser shutdown circuits to safe-guard against any possible hazard. This shutdown circuit can be configured and is active in the basic state. It trips, if no input signal is received by the optical receiver, i.e. if there is a break in the link. This prevents any uncontrolled laser emission if a fiber-optic connector is faulty or not connected.

Als Schutz gegen eventuelle Gefährdungen sind alle optischen Sender (außer an den Ethernet-Schnittstellen) mit einer au-tomatischen Laserabschaltung ausgestattet. Diese Abschaltung kann konfiguriert werden und ist grundsätzlich aktiv. Sie löst aus, wenn ein Eingangssignal am zugehörigen optischen Empfänger fehlt, z. B. bei unterbrochener Verbindung. Dies verhindert jede unkontrollierte Laserabstrahlung, wenn der optische Steckverbinder fehlerhaft oder nicht angeschlossen ist.

To ensure safe operation of the entire optical path, the laser safety shutdown must be activated.

Für den sicheren Betrieb der gesamten optischen Strecke muss die Laser-Sicherheitsabschaltung aktiviert sein.

Even with this safeguard, fiber-optic cables which are open at one end should always be considered to be “live”. Never look into open fiber-optic cable ends, as this may damage your eyes.

Auch unter Beachtung dieser Vorsichts-maßnahmen sollen Glasfaserkabel, die an einem Ende offen sind, immer so behandelt werden, als würden sie ständig Laserlicht führen. Nie direkt in die Enden sehen, da sonst die Augen geschädigt werden können!

In case of doubt always use dedicated laser-protective goggles!

Tragen Sie im Zweifelsfall stets eine Laserschutzbrille!

2.10.3 Handling Batteries / Handhabung von Batterien Some equipment may contain accumulators or batteries of different technologies − e. g. lithium batteries or others.

Bestimmte Geräte können Akkumulatoren oder Batterien verschiedener Technologien enthalten − z. B. Lithium-Batterien oder andere.

Observe the following international

standards, if applicable: IEC 60130-17 (device interconnec-tions) IEC 61429 (recycling symbol) IEC 61438 (safety and health haz-ards) IEC 60086-4 (handling lithium bat-teries)

Beachten Sie gegebenenfalls auch folgende internationale Normen: IEC 60130-17 (Geräteverbindungen)IEC 61429 (Recyclingsymbol) IEC 61438 (Sicherheits- und Gesundheitsrisiken) IEC 60086-4 (Umgang mit Lithium- Batterien)

Pay attention to error messages re-ferring to the accumulator or the battery.

Achten Sie auf Fehlermeldungen, die sich auf den Akkumulator bzw. die Batterie beziehen.

Accumulators or batteries which are inte-grated in the device should only be replaced by the equipment manufacturer.

Ins Gerät eingebaute Akkumulatoren oder Batterien sollen nur beim Gerätehersteller ausgetauscht werden.

If replacement is necessary, do not remove the accumulator or the battery from the device, but send in the complete device / the module (card) or the removable battery pack.

Wenn ein Austausch erforderlich ist, dann bauen Sie nicht den Akkumulator oder die Batterie aus dem Gerät aus, sondern schicken Sie das komplette Gerät / die Baugruppe oder das herausnehmbare Batteriepack ein.

In order to prevent loss of data, the battery should only be replaced by the equipment manufacturer.

Zur Vermeidung von Datenverlust soll die Batterie nur durch den Gerätehersteller ausgetauscht werden.

There is risk of explosion if the battery is not replaced correctly!

Wenn die Batterie nicht ordnungsgemäß ausgetauscht wird, besteht Explosionsgefahr!

If you depollute batteries, you must observe the local regulations applicable to hazardous waste.

Beim Entsorgen von Batterien müssen die örtlichen Vorschriften über Beseitigung von Sondermüll eingehalten werden.

Never short circuit batteries directly without using a discharging resistor! Without a resistor very high current will flow causing a risk of explosion!

Schließen Sie niemals Batterien direkt ohne Entladewiderstand kurz! Ohne Widerstand können so hohe Ströme fließen, dass Explosionsgefahr besteht.

2.10.4 Emergency Switching OFF / Notabschaltung

Especially if smoke or fire escapes from the device (or in other emergency situations), switch OFF the device immediately - by all relevant circuit breakers in the connector panel of the rack.

Insbesondere falls Rauch oder Feuer aus dem Gerät austritt (oder in anderen Notsituationen), schalten Sie das Gerät sofort aus - mit allen zugehörigen Sicherungsautomaten im Gestell- Anschlussfeld.

If possible, first switch OFF the protection power supply and then the working power supply.

Schalten Sie möglichst zuerst die Ersatz-Stromversorgung aus, dann die Betriebs-Stromversorgung.

However, consider that such an emergency shut-down can disconnect important communication lines which may be required just in the case of emergency.

Bedenken Sie jedoch, dass durch solch eine Notabschaltung wichtige Kommunikationsleitungen unterbrochen werden können, die gerade im Notfall eventuell dringend benötigt werden.

For this reason, shut down the device only if it is inevitable. Otherwise perform the normal switch-off procedure.

Nehmen Sie deshalb nur dann eine Notabschaltung vor, wenn es unumgänglich ist. Verfahren Sie sonst entsprechend der normalen Abschaltprozedur.

After the emergency shut-down, and if it is possible without danger, check if the device is dead - either by using a measuring device or by the LED display of the device, if ap-plicable.

Falls dies ohne Gefahr möglich ist, überprüfen Sie nach dem Notabschalten, ob das Gerät spannungsfrei ist - entweder mit einem Messgerät oder gegebenenfalls durch eine LED-Anzeige am Gerät.

3 Troubleshooting

3.1 Indicator and Control Elements on the hiT 7020 Network Elements

3.1.1 LEDS The LED displays the status of modules, there are four types of LED on the Mainboard, they are PWR, CR, MJ and MN. These comprise faulty LEDs and service/alarm LEDs, which are used particularly in maintenance tasks. Before you open the System Management Interface or remove any modules from chassis of all NEs SURPASS hiT 7020 and when doing any work with the subrack open, you must observe the measures contained in Chapter 2.

The indication of LEDs is described in the SURPASS hiT 7020 Installation and Test Manual.

3.2 TNMS-M SURPASS hiT 7020 LCT Connection Description

3.2.1 IP Address Setting There are two IP address in the Network Element, the one is Ethernet IP address, the other is the Node IP address. First of all, you should set the IP address of the SURPASS hiT7020 LCT and the NE’s Ethernet IP address in the same subnet. Then, you should add the static route on the local Server where you installed the SURPASS hiT 7020. How to set the static route please refer to TNMS-M SURPASS hiT7020 3.2 LCT User Manual. The Ethernet IP address and the Node IP address in the NE are different to each other. FTP Service have to use Ethernet IP in boot mode while use the Node IP in the running mode.

3.2.2 Trap Destination Polling Mechanism TNMS-M SURPASS hiT 7020 LCT polls the NE connected to it periodically and adds the LCT's IP address into the NE's trap destination table automatically. LCT's IP address can be added into the NE's trap destination by clicking the "Apply" button on the trap destination dialog of LCT, this dialog does not support adding any other IP into NE’S trap destination table, because it is meaningless.

3.3 Alarm Evaluation and Fault Isolation The Fig. 3.1 shows the basic options for alarm containment and alarm evaluation. Fig. 3.1 Basic Options for Alarm Containment and Alarm Evaluation Even without an operating terminal, it is possible to isolate faults as far as the module level with the aid of the module LEDs. Columns containing the relevant information are included in the alarm tables in Chapter 4.

3.4 Fault Clearance Procedures Refer to the ‘Actions’ rows in Alarm Tables in Chapter 4. They contain specific instructions regarding fault clearance.

3.4.1 Cables and Connectors Check the electrical connectors to ensure that they are fully engaged and that none of the pins is distorted. Check the optical fibers and optical connectors in accordance with the instructions given in Chapter 2. Check the cable layout (copper and optical fiber) in accordance with the wiring diagram.

3.4.2 Module Replacement Before replacing a module which is suspected of being defective, try to reactivate the system by means of a hardware reset (e. g. pulling and re-inserting the module), but do not do this if the red fault LED on the module is illuminated. When replacing modules, you must comply with the safety regulations, as described in Chapter 2.

See ITMN

A42022-L5966-B 57-1-7620 25

When replacing a module, it is essential to check and record the optical and the electrical transmitting power, using an optical or electrical power meter respectively, before the modules are returned to service. The module setup procedure can only commence once the module has been correctly inserted into the slot, as far as the stop, and then locked. Modules can be removed from or plugged into the slots while they are live. After a module has been replaced; the module status must be checked using the LCT or TNMS-M.

3.4.3 Special Fault Clearance In the event of faults occurring in the system which cannot be eliminated by applying the fault clearance procedures and instructions by the Alarm Tables, you can contact the relevant Siemens AG Service Agency. In order to provide effective support for the fault clearance operations, the following basic details will be required: - Complete reference numbers for the equipment affected by the fault - Software release numbers for the equipment affected by the fault - An accurate description of the fault (times of occurrence, apparent associations with

other factors, etc.) - Details of the attempts already made to rectify the fault.
