    Could You help me to know if the DAC 10 G is compatabile to run on this server HPC7000 and the other side EX4600 ?hp-bladesystem-c7000-blade-enclosure-8ac.jpg

    EX4600 supports 10G DAC in general, you can find the complete list of supported transceivers here:



    If HPC7000 is working with DAC transceivers as well, you need to check in your lab, especially with the DAC transceivers you are using (original Juniper or 3rd party)

    Hi HDawood,


    Good day!!


    The 24 small form-factor pluggable (SFP) network ports on EX4600 switches support 10-Gigabit Ethernet transceivers and direct-attach copper (DAC) cables. The switch also supplies four quad small form-factor pluggable plus (QSFP+) ports for use as uplinks. These 40-Gigabit Ethernet ports support QSFP+ transceivers, QSFP+ DAC cables, and DAC breakout cables (DACBO). Each QSFP+ port on an EX4600 switch can be configured to operate as 10-Gigabit Ethernet interface by using a breakout cable or as a single 40-Gigabit Ethernet interface. The ports on an EX4600 switch are disabled by default. You enable a port through the CLI.

    This can only be confirmed by testing the Juniper DAC cable with your HPE server, I don't think this is officially supported by HPE.


    Also I know that there are  4 QSFP  ports ,Can I use them with DAC 10 G ?


    10G DAC cables are SFP+ transceivers, while QSFP Ports are slots for QSFP transceivers (40G). So you cannot use 10G DAC cables with QSFP ports, as you simply cannot plug it in.
