Removing an SFP or XFP Transceiver

Small form-factor pluggables (SFPs) are optical transceivers that can be removed from a PIC (for more information, see M120 Physical Interface Cards (PICs) Description).

SFPs and XFPs are hot-insertable and hot-removable. Removing an SFP or XFP does not interrupt PIC functioning, but the removed SFP or XFP no longer receives or transmits data.

To remove an SFP or XFP transceiver (see Figure 1):

  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 wrist strap to your bare wrist and connect the wrist 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 end of a fiber-optic cable. Fiber-optic transceivers contain laser light sources that can damage your eyes.

  4. Remove the cable connector plugged into the transceiver.
  5. 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.

  6. Pull the ejector handle out from the transceiver to unlock the transceiver.

    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.

  7. 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.

  8. Using your fingers, grasp the body of the transceiver and pull it the rest of the way out of the PIC or CFPC.

  9. Place a rubber safety cap over the transceiver.
  10. Place the removed transceiver on an antistatic mat or in an electrostatic bag.

Caution: After removing a transceiver from the chassis, wait at least 30 seconds before reinserting it or inserting a transceiver into a different slot.
