Replacing a QSFP transceiver

About this task

The device supports only IBM-qualified transceivers. If you use an unqualified transceiver, the switchshow command output shows the port in a Mod_Inv state. Fabric OS also logs the issue in the system error log. Also note the following:
  • Each QSFP contains four individual 16 Gbps or 32 Gbps ports. Be aware that any problems with one port could affect all four ports in the quad if the QSFP must be replaced.
  • Although installation and removal procedures are the same for QSFP transceivers installed in port blades and extension blades, these transceivers are not interchangeable between the two blade types.
  • Some QSFPs, such as the 4x16 Gbps 2 km QSFP, have an integrated cable attached. You do not need to install a separate cable.

Complete the following steps to remove and then install a new QSFP transceiver.

Procedure

  1. Remove any cables that are inserted into the transceiver.
    Note: If your transceiver has an integrated cable, you cannot remove the cable.
  2. Grasp the transceiver pull tab and gently pull the transceiver straight out from the port.
    Note: Grasp the pull tab near the body of the transceiver to reduce the chances of bending the pull tab. As the transceiver may be hot, always use the pull tab and avoid touching the transceiver body.
  3. To insert the replacement transceiver, use the pull tab to carefully push the transceiver into the port. Transceivers are keyed so that they can only be inserted with the correct orientation. If a transceiver does not slide in easily, ensure that it is correctly oriented. Gently push the correctly oriented QSFP transceiver until the latching mechanism clicks.

    The port's status LED initially blinks amber after installation, then displays steady amber.

  4. Position a cable so that the key (the ridge on one side of the cable connector) is aligned with the slot in the transceiver. Insert the cable into the transceiver until the latching mechanism clicks.
    Note: If your transceiver has an integrated cable attached, you will not install a cable.

    The port's status LED displays steady amber until both ends of the cable are inserted and the link is established. When the link is fully established, the LED displays steady green.

    Note: Cables are keyed so that they can be inserted in only one way. If a cable does not slide in easily, ensure that it is correctly oriented.
  5. Organize cables to avoid covering LEDs and air vents. Refer to Cable management.
