  • 1.  How to patch with MX304 by 10G interface ?

    Posted 02-23-2024 05:09

    Hi, 

    I researched a while for MX304.  Seem MX304  MX304-LMIC16 supports 10G interfaces. But I checked that the Line card only provides 400G/100G ports. 

    Understand this situation, it can only support 100G/40G/25G SFP. How can I use 10G SPF to connect with other device ? 

    Is there any module to separate 100G to 10Gx10 directly? Like MPC7E, it can use QSFP+ to divide to 4x10G ports.

    The MX304 supports the Nvidia/Mellanox MAM1Q00A-QSA QSFP+ to SFP+ adapter.  That would let you use one of the 100G ports with a 10G SFP+.  Otherwise, you'd need a 4x10G QSFP+ with a breakout cable.

    Hi, 

    Under this situation, each port you can choose is Like this below ?

    1. 400G/100G/40G to occupy one port.
    2. 25Gx4 to occupy one port by an adapter 
    3. 10Gx4 to occupy one port by an adapter

    All ports on MX304 are QSFP28/QSFP-DD. Only ports with odd numbers (located in lower row) can be used for break-out connectivity. If a port is configured for 4x10G or 4x25G speed, the port above it can't be used.

    You can use Port checker tool to verify your port configuration:

    The MX304 Deep Dive mentions these...

    1GE, 10GE, 25GE, 40GE, 50GE, 100GE, 200GE, 400GE
     
    Many breakout options are mentioned also...
    2x
    3x
    4x
    8x

    https://community.juniper.net/blogs/reema-ray/2023/03/28/mx304-deepdive

    BTW, please let me know if you have a vendor that sells the rack mount that the 4x breakout cable mount into.  We can no longer get them and need a new source.
