ERROR LED: indicates the initialization status or a hardware error of the unit
•
It is red lit during the boot of the system. If it doesn’t extinguish within some
seconds, the unit needs servicing.
POWER LEDs: indicate the status of the unit power supply: MAIN (main power supply)
and BACKUP (redundant power supply).
Status:
•
Off: no mains input.
•
Green: power supply ON.
LAN LEDs: indicate the status of the audio local area network: LAN 1 (main interface)
and LAN 2 (secondary interface).
Status:
•
Off: no local network connection.
•
Blinking green: link is established at data level.
If the boards are wired to a dedicated audio network using a switch, only LAN 1 should
be blinking. If the wiring is connected in "Daisy Chain" mode, without switches, or there
is a redundant network, both LEDs should be blinking. IMPORTANT NOTE: When there
is a redundant network, primary and secondary interfaces must be connected to
separated networks.
On / Off switch.
2.3.2. Description of the back panel and connections.
2.3.2.1. Ethernet Ports (LAN 1 and LAN 2).
NETBOX DSP includes two Ethernet ports: LAN 1 must always be wired, while LAN 2 is only
used when the system is wired in "Daisy Chain" mode or a redundant system is set up.
IMPORTANT NOTE: When there is a redundant network, primary and secondary interfaces
must be connected to separated networks.
Physically, both are RJ45 10/100/1000, connectors, with the pinout described below:
