Introduction

This guide covers installation, removal and technical

information for the following SFP Transceivers:

1000BASE-SX SFP Transceiver (3CSFP91)

■

1000BASE-LX SFP Transceiver (3CSFP92)

■

Each transceiver, when installed into a 3Com Switch,

provides a high-speed Gigabit Ethernet connection over

fiber-optic cable, using a fiber optic duplex connector

(LC). These transceivers can be installed and removed

with your system powered up.

Installation and Removal

The following instructions, warnings and notes apply to

both transceivers.

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 powered-

up. 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.

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.

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.

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.

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 anti-

■

static 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 fiber connector is

toward you and the product label is visible.

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. Ensure

the wire release lever is closed (in the upright

position).

5 Use a fiber 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.

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.
