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:
1
Obtain an antistatic container for the SFPs you will remove (see
Storing Modules and Components , earlier in this chapter).
2
Put the antistatic wrist strap on your wrist, and connect the strap to
the ESD grounding jack on the system.
3 Disconnect the cables from one of the SFPs on the module.
4
Identify 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
