To remove an SFP or XFP transceiver (see
Have ready a replacement transceiver, or a transceiver slot plug, an antistatic mat,

and a rubber safety cap for the transceiver.
Attach an ESD wrist strap to your bare wrist and connect the wrist strap to one of the

later.
WARNING: Do not look directly into a fiber-optic transceiver or into the
end of a fiber-optic cable. Fiber-optic transceivers contain laser light
sources that can damage your eyes.
Remove the cable connector plugged into the transceiver.

Carefully drape the disconnected cable over the bobbins in the cable management

system below the FPC card cage to prevent the cable from developing stress points.
CAUTION: Avoid bending fiber-optic cable beyond its minimum bend
radius. An arc smaller than a few inches in diameter can damage the cable
and cause problems that are difficult to diagnose.
Pull the ejector handle out from the transceiver to unlock the transceiver.
6.
CAUTION: Make sure that you open the ejector handle completely (you
will hear it click). This prevents damage to the transceiver.
For the 10-port Gigabit Ethernet PIC, use needlenose pliers to pull the ejector handle
out from the SFP.
Grasp the transceiver ejector handle and pull the transceiver approximately 0.5 in (1.3

cm) out of the PIC or CFPC.
For the 10-port Gigabit Ethernet PIC, use needlenose pliers to grasp the SFP ejector
and pull the SFP approximately 0.5 in (1.3 cm) out of the PIC.
Using your fingers, grasp the body of the transceiver and pull it the rest of the way out
