Installing the SFP Output Module
Introduction
Installing and removing the SFP output interface cartridge requires special care. This annex
describes the process.
Rear panels incorporate one or two SFP interface(s). The interface consists of two parts:
• A socket on the rear panel into which an SFP interface module is plugged
• An SFP (Small Form-factor Pluggable) module that performs output medium
translation to which connections are made for optical fibers, coaxial copper, and so on.
Installing an SFP module
1 Make sure that the bale clasp lever is in the closed position.
CAUTION
• SFP fiber Transmitter modules contain a class 1 laser, which emits invisible
radiation whenever the module is powered up. Because the SFP is hot-
swappable, the modInstallation & Service Manualule may be powered up
as soon as it is installed.
• DO NOT LOOK INTO AN OPERATING SFP FIBER MODULE’S CONNECTORS,
AS EYE DAMAGE MAY RESULT.
• The SFP module is sensitive to electrostatic discharge (ESD). It is
recommended that you use an ESD-preventive wrist strap grounded to the
Densité 3+ FR4 chassis while handling the SFP module.
• SFP modules are subject to wear, and their useful lifetime is reduced each
time they are inserted or removed. Do not remove them more often than
is absolutely necessary.
• Never remove or install an SFP fiber module with the fiber optic cables
connected. Damage to the cables could result.
• The presence of dust and debris can seriously degrade the performance of
an optical interface. It is recommended that you insert a dust plug into the
SFP fiber module whenever a fiber optic cable is not connected.
