Introduction

Thank you for choosing the Yamaha SWP1-8, SWP1- 8MMF, or SWP1-16MMF L2 switch.
To take full advantage of the superior functions and performance offered by the SWP1, and to enjoy years of trouble-free use, be sure to read this owner’s manual carefully before operation.
This owner’s manual is intended to be read by audio networking personnel.

Included items

SWP1 Owner’s Manual (this book)
Power cord (three-pin plug)

Option item

MMF-SWP1 (optical expansion unit)
Installation must be performed by a Yamaha service engineer. Customers must not attempt to perform the installation themselves.

Precautions for Rack Mounting

This unit is rated for operation at ambient temperatures ranging from 0 to 40 degrees Celsius. When mounting the unit with other SWP1 unit(s) or other device(s) in an EIA standard equipment rack, internal temperatures can exceed the specified upper limit, resulting in impaired performance or failure. When rack mounting the unit, always observe the following requirements to avoid heat buildup:

When mounting the unit in a rack with devices such as power amplifiers that generate a significant amount of heat, leave more than 1U of space between the SWP1 and other equipment. Also either leave the open spaces uncovered or install appropriate ventilating panels to minimize the possibility of heat buildup.
To ensure sufficient airflow, leave the rear of the rack open and position it at least 10 centimeters from walls or other surfaces. If you’ve installed a fan kit, there may be cases in which closing the rear of the rack will produce a greater cooling effect. Refer to the rack and/or fan unit manual for details.

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.
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 SWP1 unit. The user can also customize the settings.
Visualize the network status
The “Yamaha LAN 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 (except the SWP1-8) 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. The internal power supply can be backed-up by providing external power (+24V) via this jack.

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, but the total amount of data must not exceed 1 Gbps. The VLAN preset A and B of the SWP1 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 SWP1 transmits VLAN 1 data via the trunk connection, the SWP1 unit that receives this will transmit the data only to the port that corresponds to its own VLAN 1.
The bandwidth of the trunk connection for the SWP1’s VLAN preset 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 SWP1’s VLAN presets enable link aggregation of the trunk connection. If the bandwidth will exceed 1 Gbps, 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 SWP1-16MMF

Front panel

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.
MMF port
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. You can expand the MMF ports by installing an optional MMF-SWP1 in the location where a cover is attached. Installation of the MMF-SWP1 must be performed by a Yamaha service engineer. Customers must not attempt to perform the installation themselves.
NOTE
• Use an opticalCON DUO multi-mode 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.
• 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
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.
LED mode indicators
This indicates what the status indicators are showing.
[LED MODE] button
This switches what the status indicators are showing.
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.”
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.

• Switch 1 (CONFIG)
Specifies whether the unit’s settings are optimized for a Dante network or are set by the user.

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 SWP1 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.

In the tables, “1,” “2,” “Tr1,” and “Tr2” respectively indicate VLAN 1, VLAN 2, trunk (LAG1), and trunk (LAG2).
For an explanation of VLAN, trunk, link aggregation, and LAG, refer to Terms on page 10. For details, you can download technical reference material (HTML).
SWP1-8/SWP1-8MMF

SWP1-16MMF
DIP switches Table 5
(1) In the VLAN presets, the IGMP Snooping function is turned on except for VLAN 2 in presets A and B, preventing multicast communication such as Dante’s multicast flow from being forwarded to unnecessary routes. For this reason, in the case of A or B you should use the VLAN 1 port for audio signals such as Dante, and use the VLAN 2 port for control signals.
(2) If you use setting C, connect the computer that is using Yamaha LAN Monitor to the VLAN 1 port.
The SWP1-8’s 9 and 10, the SWP1-8MMF’s 10, and the SWP1-16MMF’s 18 are available only if the MMFSWP1 option is installed.

[CONSOLE (RS-232C)] port
This is an RJ-45 port used to specify commands. Use an RJ-45/DB-9 serial cable to connect this to the RS-232C port (COM port) of your computer. Use an RJ-45/DB-9 serial cable that is wired as described in “Specifications.”
[POWER] indicator
This is lit when the SWP1 is powered-on.

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.

10. 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 SWP1’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.

11. [EXT DC INPUT] connector

This is an XLR-4-32 type jack for supplying an external power supply (+24V) as a backup for the SWP1’s internal power supply.

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 SWP1 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.

12. 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.
The SWP1-16MMF’s ports 9 through 12 are conventional RJ-45 ports. The others are etherCON (RJ45) ports.
All ports support 1000BASE-T, 100BASE-TX, and 10BASE-T.

Status Indicator Display

The status indicators show different things depending on the LED mode setting.

LINK/ACT setting

The status indicators show each port’s link status and connection status.

STATUS setting

The status indicators show the loop-related port’s status.

VLAN setting

The status indicators show the VLAN ID and trunk. If DIP switch 1 is upward ([DANTE]), VLAN 1 is shown by the upper indicator and the lower indicator unlit. VLAN 2 is shown by the upper indicator lit green and the lower indicator unlit. Trunk is shown by upper and lower indicators lit orange.

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.
