Small form-factor pluggable (SFPs) and XFPs are optical transceivers
that are installed in IOCs and SPCs.
SFPs and XFPs are hot-insertable and hot-removable. Removing
an SFP or XFP does not interrupt IOC or SPC functioning,
but the removed SFP or XFP no longer receives or transmits data.
To remove an SFP or XFP transceiver (see Figure 64):
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 ESD points on the chassis.
Label the cables connected to the transceiver so
that you can reconnect them correctly 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 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.
Caution:
Make sure that you open the ejector handle completely until
you hear it click. This prevents damage to the transceiver.
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 IOC.
Using your fingers, grasp the body of the transceiver
and pull it the rest of the way out of the IOC.
Figure 64: Removing SFPs or XFPs
Place a rubber safety cap over the transceiver.
Place the removed transceiver on an antistatic
mat or in an electrostatic bag.
