Figure 7-4 Installing an SFP on an ERX GE I/O module
4Insert 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.
5Gently 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.
6Remove the dust cover that protects the ports.
7Connect the new cables to the SFP.
If you are using the redundant port on the ERX GE I/O module, repeat steps 2 through 7 for the other port.
Verifying the Installation
When you have replaced the SFPs and connected the cables, issue the show interface gigabitEthernet command for each interface to check that the interface is operational (up).
