Installation and Removal

Safety Precautions

Be sure you follow all safety precautions when you install or replace an SFP Transceiver. To avoid electric shocks and burns to yourself and damage to the equipment, read and follow these warnings:

WARNING : When the system is on:

■

Never insert a metal object such as a screwdriver or a finger with jewelry into open module slots

Do not touch any connections inside the chassis with your hands or fingers.

WARNING : Fiber Optic ports - Optical Safety.

Never look at the transmit laser while it is poweredup. Never look directly at the fiber TX port and fiber cable ends when they are powered-up.

WARNING : Use of controls or adjustments of performance or procedures other than those specified herein may result in hazardous laser emissions.

WARNING : RJ-45 Ports. These are shielded RJ-45 data sockets. They cannot be used as standard traditional telephone sockets, or to connect the unit to a traditional PBX or public telephone network.

Only connect RJ-45 data connectors, network telephony systems, or network telephones to these sockets.

Either shielded or unshielded data cables with shielded or unshielded jacks can be connected to these data sockets.

AVERTISSEMENT : Quand le systeme est allumé:

■

Ne jamais introdure d'objet métallique, tel qu' un tourne vis ou meme votre doight si vous portez un bijou dans le reserve au module.

Ne touchez aucun engrenage à l' interieur du chasis avec le doight ou la main.

AVERTISSEMENT : Ports pour fibres optiques – sécurité sur le plan optique.

Part No. DIASFP91-AAA03

Published October 2003

Ne regardez jamais le laser tant qu'il est sous tension.

Ne regardez jamais directement le port TX

(Transmission) à fibres optiques et les embouts de câbles à fibres optiques tant qu'ils sont sous tension.

AVERTISSEMENT : L'utilisation de contrôles, de réglages de performances ou de procédures autres que ceux qui sont spécifiés au sein du présent document risquent d'entraîner l'exposition à des rayonnements laser dangereux.

AVERTISSEMENT : Points d’accès RJ-45. Ceux-ci sont protégés par des prises de données. Ils ne peuvent pas être utilisés comme prises de téléphone conventionnelles standard, ni pour la connection de l’unité à un réseau téléphonique central privé ou public. Raccorder seulement connecteurs de données RJ-45, systèmes de réseaux de téléphonie ou téléphones de réseaux à ces prises.

Il est possible de raccorder des câbles protégés ou non protégés avec des jacks protégés ou non protégés à ces prises de données.

VORSICHT : Wenn das Betriebssystem angeschaltet ist:

■

Führen Sie niemals einen Metallgegenstand wie z.B. einen Schraubenzieher oder einen beringten

Finger in den offenen Modulschlitz ein.

Berühren Sie keine Verbindungen innerhalb des

Gehäuses mit Ihren Händen oder Fingern.

VORSICHT : Faseroptikanschlüsse – Optische

Sicherheit.

Niemals ein Übertragungslaser betrachten, während dieses eingeschaltet ist. Niemals direkt auf den Faser-

TX-Anschluß und auf die Faserkabelenden schauen, während diese eingeschaltet sind.

VORSICHT : Die Verwendung von Steuerelementen oder die Anpassung von Leistungen und Verfahren in anderer als der hierin genannten Weise kann zu gefährlichen Laseremissionen führen.

VORSICHT : RJ-45-Porte. Diese Porte sind geschützte

Datensteckdosen. Sie dürfen weder wie normale traditionelle Telefonsteckdosen noch für die

Verbindung der Einheit mit einem traditionellem privatem oder öffentlichem Telefonnetzwerk gebraucht werden. Nur RJ-45-Datenanscluße,

Telefonnetzsysteme or Netztelefone an diese

Steckdosen anschließen.

Entweder geschützte oder ungeschützte Buchsen dürfen an diese Datensteckdosen angeschlossen werden.

Handling SFPs

To prevent potential damage from electrostatic discharge, always observe the following when handling SFP

Transceivers:

■

Always wear an anti-static wristband connected to a suitable earth point.

Do not remove an SFP Transceiver from its packaging until you are ready to install it into a switch.

Do not touch any of the pins, connections or components of an SFP Transceiver.

Always store or transport an SFP Transceiver in antistatic packaging.

Regulatory Compliance

Laser Eye Safety: FDA 21(J) CFR, EN 60825-1/2.

Electrical Safety: EN/UL 60950

Inserting the Transceiver

The SFP Transceiver is keyed and there is only one way in which it can be installed correctly. It is not necessary to power-down your Switch.

1 Read and follow all safety precautions stated earlier in this guide.

2 Hold the transceiver so that the connector is toward you and the product label is visible. Ensure the wire release lever is closed (in the upright position). See

Figure 1.

3 Gently slide the transceiver into the SFP port until it clicks. If the transceiver does not click into place, remove it, turn it over and re-insert.

4 Remove the plastic protective cover if fitted.

5 Use an appropriate cable to connect the transceiver to a suitable device.

Removing the Transceiver

It is not necessary to power-down your Switch.

1 Disconnect the cable from the transceiver.

2 Move the wire release lever downwards until it is pointing toward you.

3 Pull the wire release lever toward you to release the catch mechanism; the transceiver will then easily slide out.

Problem Solving

If you suspect a problem, carry out these steps before contacting your supplier:

■

Refer to the documentation supplied with your Switch for general problem solving information.

Ensure that you have followed the installation instructions in this guide, and the transceiver is correctly installed in the Switch.

Ensure that the Switch in which the transceiver is fitted

■

■ is powered-up.

Ensure that the device at the far end of the link is powered-up and operating correctly.

Ensure that all connectors on the fiber optic segment are correctly engaged (1000BASE-SX, 1000BASE-LX,

1000BASE-LH70 SFP Transceivers only).

Clean the fiber terminators by wiping them gently with a clean tissue or cotton bud moistened with a little ethanol. Dirty fiber terminators on the fiber optic segment impair the quality of the light transmitted through the cable (1000BASE-SX, 1000BASE-LX,

1000BASE-LH70 SFP Transceivers only).

To remove an LH70 SFP Transceiver that has been inserted with the wire release lever pointing down, push the blue plastic at the base of the transceiver inwards towards the unit to release the catch mechanism.

Technical Specifications

1000BASE-LH70, 1000BASE-SX, 1000BASE-LX SFP Transceivers

The 1000BASE-LH70 SFP Transceiver supports a direct connection to single-mode fiber-optic cable, the 1000BASE-SX SFP Transceiver supports a direct connection to multi-mode fiber-optic cable and the 1000BASE-LX SFP Transceiver supports a direct connection to both. Table 1 shows the ranges for each connection.
