Replacing SFP, SFP+, and XFP Transceivers on the SRX3400 Services Gateway

 

Small form-factor pluggable (SFP), enhanced small form-factor pluggable (SFP+), and 10-Gigabit SFP (XFP) are transceivers that you install in sockets in various cards or modules in the services gateway. These transceivers are hot-insertable and hot-removable. Removing a transceiver does not interrupt the functioning of the card or module, but the removed transceiver no longer receives or transmits data.

Caution

If you face a problem running a Juniper Networks device that uses a third-party optic or cable, the Juniper Networks Technical Assistance Center (JTAC) can help you diagnose the source of the problem. Your JTAC engineer might recommend that you check the third-party optic or cable and potentially replace it with an equivalent Juniper Networks optic or cable that is qualified for the device.

For the services gateway to meet NEBS and ETSI standards, all transceivers installed in the services gateway must be of extended temperature (ET) type.Table 1 describes the applicable transceivers available from Juniper Networks.

To replace an SFP, SFP+, or XFP transceiver:

  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 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 cables 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 until you hear it click. This prevents damage to the transceiver.

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

  9. Place a rubber safety cap over the transceiver.
  10. Place the removed transceiver on an antistatic mat or in an electrostatic bag.
  11. Repeat steps 3 through 10 for each transceiver you need to replace.
  12. Take each new transceiver to be installed out of its electrostatic bag and identify the port on the IOC where it will be installed.
  13. Verify that each transceiver is covered by a rubber safety cap. If it is not, cover the transceiver with a safety cap.
  14. Carefully align the transceiver with the slot in the SFB or CFM. The connectors should face the SFB or CFM.
  15. Slide the transceiver until the connector is seated in the SFB or CFM slot. If you are unable to fully insert the transceiver, make sure the connector is facing the right way.
  16. Close the ejector handle of the transceiver.
  17. Remove the rubber safety cap from the transceiver and the end of the cable. Reconnect the cables into the transceivers.
  18. Verify that the status LEDs on the SFB or CFM faceplate indicate that the SFP or XFP is functioning correctly. You can also verify that the SFB or CFM is functioning by issuing the show chassis fpc pic-status command.
