Installing an SFP Module
When installing SFP modules, observe these general precautions:
To install an SFP module, follow these steps:
Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface.
To avoid damage to the converter module, first install the converter module in the switch 10-Gigabit
Ethernet slot before installing the SFP modules.
For switches without SFP module slots, install a converter module in the 10-Gigabit Ethernet module
slot as described in the
Find the send (TX) and receive (RX) markings that identify the top side of the SFP module.
On some SFP modules, the send and receive (TX and RX) markings might be replaced by arrows that
show the direction of the connection, either send or receive (TX or RX).
If the SFP module has a bale-clasp latch, move it to the open, unlocked position.
For 24- and 48-port switches, position the SFP module face up to install in the upper converter module
slot (slot 1). Position the module face down to install in the lower converter module slot (slot 2). See
For Catalyst 3560E-12D switches, position the SFP module top facing right to install in a converter
module slot. See
For Catalyst 3560E-12SD switches, position the SFP module face up to install it in a module slot. See
If the module has a bale-clasp latch, close it to lock the SFP module in place.
Remove the SFP dust plugs and save.
Connect the SFP cables.
Do not remove the dust plugs from the SFP modules or the rubber caps from the fiber-optic cable
until you are ready to connect the cable. The plugs and caps protect the module ports and cables
from contamination and ambient light.
Removing and installing an SFP module can shorten its useful life. Do not remove and insert any
SFP module more often than is absolutely necessary.
To prevent ESD damage, follow your normal board and component handling procedures when
connecting cables to the switch and other devices.
