4
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 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).
