Features

• Recommended settings for Dante are provided
  Recommended settings (such as QoS, EEE, and IGMP Snooping) for stable operation of the Dante network can be specified with only DIP switch. The 10GBASE-SR/LR ports support 10 gigabit, allowing operation without fear of insufficient bandwidth even on a Dante network that is set to a sampling frequency of 96 kHz.

• VLAN presets provided
  Three types of preset VLAN settings are provided, allowing a more stable network to be constructed by dividing audio signals and control signals with a single SWP2 unit. The user can also customize the settings.

• Visualize the network status
  The “Yamaha Audio Network Monitor” Windows application allows you to monitor the status of the network and the Dante devices. The unit’s indicators also show which VLAN is connected to which port.

• Hardware that supports safety and peace of mind
  All models can be rack-mounted. In consideration of temporary setups or other environments in which cables are liable to be pulled out, etherCON and opticalCON are provided as standard. In addition to an AC IN jack with V-lock, an XLR-4-32 type EXT DC INPUT jack is also provided. Redundant power can be provided by using a PA-700 or other external power supply (+24V).

Related software
If you are using VLAN, connect the computer to the VLAN 1 port.

• Yamaha Audio Network Monitor (Windows application)
  This is used to monitor the entire network, including SWP2 data as well as all Dante devices on the Dante network.
  Download this application from the following website. http://www.yamahaproaudio.com/

• Web GUI
  Use this to view or edit the settings of SWP2 units on the network from a web browser.
  Access the Web GUI from the Yamaha Audio Network Monitor.
  To use the Web GUI, connect a computer to the VLAN 1 port.
  When accessing the Web GUI, the “Windows Security” dialog box may appear. With the factory settings, the administrative password is set as follows.

Terms

• VLAN
  This stands for Virtual Local Area Network. A virtual network is constructed separately from the physical connections. When there are multiple networks of differing types, setting up a VLAN allows a logically separate network to be constructed that shares the same physical switches.
  A VLAN can be either a “Port-based VLAN” which constructs groups using a physical connection for each port, or a “Tag VLAN” which differentiates VLAN groups by assigning a tag to each Ethernet frame. In the case of a port-based VLAN, each VLAN requires a connection to communicate with another switch. Using a tag VLAN allows multiple VLANs to be combined into a single trunk connection (cable) that connects switches, ensure that the total amount of data does not exceed 1 Gbps for the LAN ports or 10 Gbps for the 10GBASE-SR/LR ports. The VLAN preset A and B of the SWP2 use tag VLAN.

• Link aggregation
  Link aggregation is a function that bundles multiple LAN/SFP+ ports that connect network devices, and treats them as a single logical interface in order to expand the communication bandwidth. A group that is bundled using link aggregation is called a link aggregation group (LAG).
  Link aggregation is a technology that is useful when multiple communications are occurring. The communications can be distributed between the aggregated connections by using a load balancing function. Since load balancing distributes the load according to IP address, we recommend that you fix the IP addresses of each device in order to stabilize load balancing.
  Even if a problem occurs on one of the LAN/SFP+ ports that are bundled by link aggregation, so that this port is unable to communicate, communication will continue via the remaining ports.

• Trunk
  This function adds tags to multiple VLANs so that they can be transmitted and received via a single connection. When one SWP2 transmits VLAN 1 data via the trunk connection, the SWP2 unit that receives this will transmit the data only to the port that corresponds to its own VLAN 1.
  Communication speed for a metal trunk connection on the SWP2’s VLAN preset B is 1 Gbps per cable. If there is only one cable, and the total bandwidth passing through the trunk connection exceeds
  1 Gbps, packets will be delayed or dropped. Some of the SWP2’s VLAN presets enable link aggregation of the trunk connection. If the bandwidth will exceed
  1 Gbps for a LAN port or 10 Gbps for a 10GBASE-SR/LR port, or if you want to provide redundancy to guard against cable breakage, you should use two trunk cables.

Controls and Functions

Front panel
The explanation here is based on the SWP2-10MMF.

1. LAN ports
   These are etherCON (RJ-45) ports for connecting Ethernet cables (CAT5e or better is recommended). A cable with an RJ-45 connector can also be connected.
   All ports support 1000BASE-T, 100BASE-TX, and 10BASE-T.

2. 10GBASE-SR ports (SWP2-10MMF)/ 10GBASE-LR ports (SWP2-10SMF)
   This is an opticalCON DUO port for connecting an optical fiber cable. LC Duplex connectors can also be connected.
   If you use a cable with an LC Duplex connector, fasten the dust cap attached to the cable connector to prevent dust from adhering when the cable is not in use.
   NOTE

   • Use an opticalCON DUO optical fiber cable made by Neutrik Corporation. Since optical fiber cables are vulnerable to being bent or pulled, you can reduce the occurrence of problems by using a cable that has a strong sheath and is equipped with a locking mechanism.
   • The SWP2-10MMF can use GI-type multi-mode fiber cables that have a core diameter of approximately 50 μm and cladding diameter of approximately 125 μm. The maximum length between devices is 300 m.
   • The SWP2-10SMF can use SM-type single-mode fiber cables with a core diameter of approximately 9 μm and a cladding diameter of approximately 125 μm. The maximum length between devices is 10 km.
   • In some cases, the specifications might not be satisfied because of the optical fiber cables that are used and the conditions of installation.
   • Link up is possible only for 10GBASE-SR/LR between the same standards. 10GBASE-SR/LR can not link up with 1000BASE optical standards.
     Cleaning
     Correct communication might not be possible if debris and/or dust has adhered to the ends of optical fiber cables or the ports. Clean the equipment regularly by using commercially available optical fiber cleaning products.

3. LED mode indicators
   This indicates what the status indicators are showing.

4. [LED MODE] button
   This switches what the status indicators are showing.

5. Status indicators
   These indicate the status of each port. The displayed content depends on the mode. For details on the display in each mode, refer to “Status indicator display.”

6. DIP switches
   These specify startup settings for the unit.
   Set the DIP switches when the power is turned off. The settings are not applied if you change the setting while the power is on.
   The switch illustrations indicate the up/down position as follows.

DANTE

| The unit starts up with settings optimized for a Dante network. This setting is read only.

1

|

USER

| The unit starts up with user settings. This setting can be read or written; when you change the setting, the unit starts up the next time as well with that setting.

Caution when using this unit together with another manufacturer’s switch

Dante supports both IGMP V2 and V3, but you must set all switches in the same network to operate using the same version.
If the SWP2 starts up with DANTE settings, it operates using IGMP V3. In this case, if the network includes even one switch that is operating with IGMP V2, problems such as dropouts in the sound might occur.

Switch 2 and 3 (VLAN PRESET)
Specifies the VLAN preset that is used when switch 1 is in the [DANTE] position. This setting is ignored if switch 1 is set to [USER].
If you change the settings via the web GUI or a command, the settings are applied temporarily but is not stored; the next time the unit starts up, it returns to the VLAN preset setting.

Rear panel

Grounding screw
Since the included power cord has a three-pin plug, this unit will be appropriately grounded if the AC outlet is grounded. In some cases, you may be able to reduce hum noise and interference noise by connecting this screw to ground as well.

AC IN connector

Connect the included power cord here. First connect the power cord to this unit, and then connect the power supply plug to an AC outlet; the SWP2’s internal power supply turns on.
The supplied AC power cord features a V-lock mechanism via a latch, which prevents the power cord from coming off accidentally.
Insert the cable plug all the way until it locks in securely.
Press the latch button on the plug to disconnect the power cord.

[EXT DC INPUT] connector
This is an XLR-4-32 type jack for supplying an external power supply (+24V) as a backup for the SWP2’s internal power supply.
Connect a Yamaha PA-700 AC adaptor or an equivalent product recommended by Yamaha.

CAUTION

• Before connecting the external power supply, you must turn off the external power supply. Failing to do so may cause electrocution or malfunctions.
• EXT DC INPUT connector is intended to be supplied by Power Supply certified with “Limited Power Source” or “LPS” and rated 24 Vdc.

NOTE

• If an external power supply is connected, the SWP2 will operate normally when its internal power supply and the external power supply are on, as well as when only one is on.
• If both power supplies are on, and one of them is interrupted during operation, the unit will continue to operate normally.

LAN ports

These are etherCON (RJ-45) ports for connecting Ethernet cables (CAT5e or better is recommended). A cable with an RJ-45 connector can also be connected.
All ports support 1000BASE-T, 100BASE-TX, and 10BASE-T.

VLAN Use Cases

Redundant Dante connections

This case double the cables between devices as a safeguard against cable breakage. This diagram shows a setup using VLAN preset C.

Separating control signals from audio signals
This case logically separates control signals such as for Editor or StageMix from Dante’s audio signals, making the network more stable. This diagram shows a setup using VLAN preset B.
If VLANs are not used, and control signals and audio signals flow across the same network, the two will compete for communication bandwidth. In order to prevent such an effect, we recommend that you use VLANs to separate the control signal and audio signal networks.
