Replacing an SFP or XFP Transceiver from an MX240 DPC, MPC, MIC, or PIC
Small form-factor pluggable transceivers (SFPs) and XFPs are optical transceivers that
are installed in a DPC, MPC, MIC, or PIC. SFPs and XFPs are hot-insertable and
hot-removable.

Removing an SFP or XFP Transceiver from an MX240 DPC, MPC, MIC, or PIC
Removing an SFP or XFP does not interrupt DPC, MPC, MIC, or PIC functioning, but the
removed SFP or XFP no longer receives or transmits data.
To remove an SFP or XFP transceiver (see Figure 144 on page 324):
1. Have ready a replacement transceiver or a transceiver slot plug, an antistatic mat,
and a rubber safety cap for the transceiver.
2. Attach an ESD grounding strap to your bare wrist and connect the strap to one of the
ESD points on the chassis.
3. 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
ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cable
connected to a transceiver emit laser light that can damage your eyes.
4. Remove the cable connector from the transceiver.
5. 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 transceiver.
6. Grasp the transceiver ejector handle, and pull the transceiver approximately 0.5 in. (1.3
cm) out of the DPC, MPC, MIC, or PIC.
7. Using your fingers, grasp the body of the transceiver, and pull it the rest of the way
out of the DPC, MPC, MIC, or PIC.
