Replacing SFPs on GE I/O Modules
E-Series Routers
9-11
Caution: Be sure to position the SFP correctly before you install it.
3 Hold the SFP so that:
• The connection circuitry is adjacent to the TX and RX markings
on the module’s faceplate.
• The front will be visible when you install the SFP.
For a picture of the correct orientation, see Figure 9-6 .

Insert the SFP as far as you can into the I/O module.
The SFP should slide smoothly into the I/O module and should click
into place. If the SFP does not slide smoothly into the I/O module,
check that the orientation of the SFP is correct.
5 Gently pull the SFP to confirm that it is inserted correctly.
The SFP should not move when you pull it. If the SFP comes out of
the slot when you pull it, repeat step
4 .
6 Remove the dust cover that protects the ports.
7 Connect the new cables to the SFP.
If you are using the redundant port on the E-series GE I/O module,
repeat steps
2 through 7 for the other port.
