Cisco SFP and SFP+ Transceiver Module Installation Notes

Removing SFP and SFP+ Transceiver Modules

Step 14 Observe the port status LED:

• The LED turns green when the SFP transceiver module and the target device have an established

link.

• The LED turns amber while the STP feature discovers the network topology and searches for

loops. This process takes about 30 seconds, and then the LED turns green.

• If the LED is off, the target device might not be turned on, there might be a cable problem, or

there might be a problem with the adapter installed in the target device. See the Troubleshooting

section of your switch hardware guide for solutions to cabling problems.

Step 15 Reconfigure and reboot the target device if necessary.

Removing SFP and SFP+ Transceiver Modules

Caution The SFP and SFP+ transceiver modules are static sensitive devices. Always use an ESD wrist strap or

similar individual grounding device when handling the transceiver modules or coming in contact with

modules.

Caution Be careful when removing GLC-GE-100FX SFPs from a WS-C3750G-12S-S switch. The SFP

transceiver module temperature might go over 160°F (70°C) and be too hot to touch with bare hands.

If you are removing an SFP or SFP+ transceiver module, follow these steps:

Step 1 Attach an ESD-preventive wrist strap to your wrist and to the ESD ground connector or a bare metal

surface on your chassis.

Step 2 Disconnect the network fiber-optic cable or network copper cable from the transceiver module

connector. For optical transceiver modules, immediately reinstall the dust plugs in the transceiver

module’s optical bores and the fiber-optic cable LC connectors.

Tip For reattachment of fiber-optic cables, note which connector plug is send (TX) and which is receive

(RX).

Step 3 Release and remove the transceiver module from the socket connector, as shown in Figure 11, Figure 12,

Figure 13, or

• If the SFP transceiver module has a Mylar tab latch, pull the tab gently in a slightly downward

direction until the transceiver disengages from the socket connector, and then pull the SFP

transceiver module straight out. Do not twist or pull the Mylar tab because you could detach it from

the SFP transceiver module.
