ETHERNET SWITCH INFORMATION
Important information about myMix and off-the-shelf Ethernet switches
  • Three or more myMix require an Ethernet switch (two myMix can be connnected directly to each other).
  • A myMix system with 16 or less channels, powered by the included power supplies, can use a standard 100Mbs unmanaged Ethernet switch.
  • POE (power over Ethernet) switches may be used to power each myMix. POE switches must be able to provide 15.4 watts of power on each port at the same time. Be cautious of marketing language that states "up to X watts per port". In many cases this is misleading and generally means that only a few of the ports will pass that amount of power at the same time. The best way to tell if a POE switch will power all of your myMix is to find the overall POE budget of the switch and divide that by 15.4. This will give you the number of myMix that can be powered by the switch.
  • A myMix system with more than 16 channels requires a managed switch. In many cases, POE switches that have enough wattage (POE budget) to adequately power several myMix are also managed. Managed switches should be configured with the following general settings (different manufacturers use different nomenclature, so if you are unsure contact the switch manufacturer directly):
    • Create a VLAN 2
    • Under Port Settings, set all ports within VLAN 2 to General
    • Under VLAN to Ports, set all ports within VLAN 2 to Tagged
    • IGMP Snooping status must be enabled for all VLAN
    • IGMP Querier status must be enabled for all VLAN
    • Bridge Multicast Filtering must be enabled for all VLAN
    • Unregistered Multi-cast must be set for Filtering on all ports
    • To allow proper synchronisaton (myMix uses PTP IEEE1588-2008, layer 2 transport), the clock needs to be exempt from filtering.  
    • If you plan to use multiple switches you need to configure a GB port on the switch as uplink to forward receive all data
    • They also need to be set to different IP addresses.
    • Note: myMix devices generate their IP addresses automatically (IPv4 Link-Local)

    • If you are connecting multiple switches you must assign a unique IP address to each switch

  • We recommend the Cisco 300 series family of switches as they are readily available around the world. The POE versions are extremely capable and provide a great value for the money. We offer preconfigured Cisco switches, or you can source and configure one of these switches yourself :
    • Cisco SF302-08 - non POE managed switch with 8 100Mbs ports and 2 GB ports
    • Cisco SF302-08MP - POE switch with 8 100Mbs ports and 2 GB ports, will power up to 8 myMix via POE
    • Cisco SF300-24P - POE switch with 24 100Mbs ports and 4 GB ports, will power up to 12 myMix via POE
    • Cisco SF300-48P - POE switch with 48 100Mbs ports and 4 GB ports, will power up to 24 myMix via POE 
  • Here are the instructions how to use the configuration files for a 300 Series switch.

  • On SF302-08MP port G2 is for uplink (to connecet a secend switch) only, the G1 can be used as the first 8 ports, without POE.
  • On SF300-24P and SF300-48P G4 is configured as uplink. If you use 2 switches that need to be connected via their uplink ports.
