Description:
Info
Some customers have reported that certain 16Gb and 32Gb small form-factor pluggables (SFPs), which use a pull tab for insertion and extraction, have gotten stuck in the cage, leaving them unable to be extracted. Attempts to apply force on the pull tab for removal can result in damage to the SFP. In certain instances the customer ended up pulling the tab completely out of the SFP. Only a small number of 16Gb and 32Gb SFPs on HPE B-series switches and directors will experience this issue, as it occurs infrequently and at random. Symptoms of this condition include the occurrence of more than typical extraction force necessary to extract an SFP; the best time to take action is at the point when this is noticeable. Typical extraction of an SFP in an HPE B-series switch or director is 12 newtons (1.2Kg) of force. HPE recommends following the actions in the Resolution section for any SFP that experiences a force that is double the typical amount of extraction force.
Scope
This advisory applies to all HPE B-series switches which use 16Gb and 32Gb SFPs with pull tabs.
Resolution
When the occurrence of more than typical extraction force is necessary to extract an SFP, follow the steps below in order to extract the SFP: Do not pull simultaneously on the optical patch cord and the SFP pull tab: Remove the optical cables and loop-backs prior to extracting the SFP. External extraction forces on the SFP can exacerbate the jamming condition. Push on the SFP nose with your thumb (or equivalent) while pulling on the pull tab to unload the shear pin during SFP extraction: The shear pin is the pin that gives the necessary retention force needed to keep the SFP plugged in when external forces (pulling the cable, for example) are pulling on it. By pushing on the SFP nose, it helps to unload it from the cage latch, allowing the pull tab to retract it, thus extracting it from the cage: In cases where it is difficult to get two hands onto a port, push in on the SFP before pulling out: Should the SFP be damaged to the point where the SFP pull tab pulls out, you will need to use needle nose pliers to extract the SFP. Use the push/pull method for extraction with pliers, which unloads the shear pin during SFP extraction: If the SFP is still unable to extract using needle nose pliers, then you will need to use a small, long, flat head screwdriver to lift up on the cage latch at the same time you extract with the needle nose pliers: NOTE : Do not reuse the SFP after extracting with pliers. NOTE: Products sold prior to the November 1, 2015 separation of Hewlett-Packard Company into Hewlett Packard Enterprise Company and HP Inc. may have older product names and model numbers that differ from current models.
