ex4300 errors when installing a specific transceiver that works fine on other switches

  • 1.  ex4300 errors when installing a specific transceiver that works fine on other switches

    Posted 13 days ago
    So i'm trying to utilize an aquantia aqs-107 copper transceiver which is specifically designed to support multigig 2.5/5/10g ethernet on an sfp+ port.  What's strange is this used to work on this very switch, i had this config running for over a year and then one day it stopped working.  I assumed the transceiver died.  I got another 10gb copper transceiver from fs.com, and it worked fine, i've also tried 10gtek and microtik copper transceivers with no issue.

    I managed to source some more of these aqs-107 transceivers and none of them will work on the ex4300.... Strange, so i put them in an old dell switch i had and all of them (including the one i thought died) came up with zero issues.

    If i run a 'show chassis hardware' with any aqs transceiver installed, it does not detect the transceiver at all.  same if i run 'show chassis pic fpc-slot 0 pic-slot 2' it will not show the transceiver if it's an aqs transceiver.

    If look at var log messages i get spammed with errors such as these that keep repeating

    I understand that is probably not a supported config with a non juniper transceiver, but my confusion is that this used to work, it worked for a year until it just stopped working.

    Could this be some kind of hardware issue with my EX-UM-4X4SFP add on card?
