Replacing SFPs on GE I/O Modules

This section describes how to replace small form-factor pluggable transceivers (SFPs) on Gigabit Ethernet (GE) 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.

Warning: Do not insert any metal object, such as a screwdriver, or place your hand into an open slot or the backplane when the E-series 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.

Caution: 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.

Removing SFPs

To remove the SFPs:

1Obtain an antistatic container for the SFPs you will remove (see Storing Modules and Components, earlier in this chapter).

2Put the antistatic wrist strap on your wrist, and connect the strap to the ESD grounding jack on the system.

3Disconnect the cables from one of the SFPs on the module.

4Identify the release mechanism for the SFP.

Different SFPs use different release mechanisms (see Figure 9-4). Possible release mechanisms include:

•A button that you press inward

•A ring that you press inward

•A bar that you pull sideways, then outward

•A tab that you pull sideways, then outward
