    when tried to upgrade the software version on this switch to the recommended one which is 19.1R3-S2
    through the USB and followed the steps mentioned inside this article through this link :

    but unfortunately didn't find the option of boot from USB !
    Please advise

    Another inquiry this Part number of SFP ( 740-013111 ) was inserted inside EX4650 but didn't work, However it runs on EX 4600 !
    and from the hardware compatibility tool we can see both EX 4650 and EX 4600 support this part number of SFP ( 740-013111 )
    from this link :
    please advise  why on EX 4650 didn't work does this related to software version run on the switch ..
