This section describes how to replace small form-factor pluggable transceivers (SFPs) on modules that support these devices. A range of SFPs that support different optical modes (multimode and single mode) and cabling distances is available. You can replace the SFPs without disabling the interfaces or removing the module from the system.
Do not insert any metal object, such as a screwdriver, or place your hand into an open slot or the backplane when the router is on. Remove jewelry (including rings, necklaces, and watches) before working on equipment that is connected to power lines. These actions prevent electric shock and serious burns.
When handling electronic components, use an antistatic wrist strap connected to the system's ESD grounding jack, and hold components by their edges. Do not touch, pins, leads, or solder connections. Store components in antistatic bags. These actions help to protect modules from damage by electrostatic discharge.
To remove the SFPs:
Different SFPs use different release mechanisms. (See Figure 40.) Possible release mechanisms include:
For port redundancy to operate correctly, both the primary and redundant ports on a GE I/O module must use the same type of SFP.
To install SFPs:
The cable connectors are protected by a dust cover.
Figure 41: Example of SFP
Be sure to position the SFP correctly before you install it.
For the correct orientation, see Figure 42.
Figure 42: Installing an SFP on a GE I/O Module
If the SFP does not slide smoothly into the I/O module, make sure that the orientation of the SFP is correct.
If the SFP comes out of the slot when you pull it, repeat Step 4.
If you are using the redundant port on the GE I/O module, repeat Steps 2–7 for the other port.
After you have replaced the SFPs and connected the cables, issue the show interface gigabitEthernet command for each interface to make sure that the interface is operational (up).
