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.
