MY16-CII Owner’s Manual

 Panel Connectors and Indicators

1 [PRIMARY] and 2 [SECONDARY] Connectors

These are 100Base-TX Ethernet connectors. The MY16-CII provides two Ethernet connectors to allow

construction of redundancy networks employing dual (primary and secondary) circuits. The [PRIMARY]

connector is for connection to the main circuit, while the [SECONDARY] connector is for connection to

the backup circuit.

If a failure occurs on the PRIMARY circuit (e.g. a cable failure, accidental disconnection, network switch

failure, etc.) the SECONDARY circuit will automatically take over. Basic redundancy network setup is

described on page13.

Use STP (Shielded Twisted Pair) cables to protect against electromagnetic interference.

3 [IN USE/CONDUCTOR] Indicators

These are the LED indicators to the left of the [PRIMARY] and [SECONDARY] connectors.

These indicators will light when power has been properly applied to the MY16-CII card. These indicators

will flash when the MY16-CII is operating as the network conductor. If an error occurs on the connected

network, both the [PRIMARY] and [SECONDARY] connector [IN USE/CONDUCTOR] indicators will flash

orange.

If both the [PRIMARY] and [SECONDARY] connector [IN USE/CONDUCTOR] indicators flash orange,

try disconnecting the corresponding Ethernet connectors. The indicator will go out if a cable, network

switch, or other device connected to the network has failed. If the indicator continues flashing orange

even after the cable is disconnected, there may be a fault in the MY16-CII card itself. In this case please

refer the problem to qualified Yamaha service personnel.

4 [LINK/ACTIVITY] Indicators

These are green indicators to the right of the [PRIMARY] and [SECONDARY] connectors. The indicator

for each connector will light or flash slowly when a network cable is properly connected, and will flash

rapidly while data is being properly transferred via the corresponding connector.

5 MAC Address

The MAC (Media Access Control) address allows the CobraNet Manager to differentiate between

individual MY16-CII unuts.
