NetMax N8000 System Controller
Owner’s manual
clock master breaks down or is removed from the network, another N8000 will take over this
function automatically.
SYSTEM STATUS-LEDs
These LEDs indicate device or system states. The READY-
LED is on when the device has booted after switch-on and
when it is ready for operation. An illuminated FAULT-LED
indicates an internal error in the N8000 or an error in the
NetMax system. During the configuration of the N8000, it
can be specified which errors should be displayed. If the FAULT display is on, the error should be
identified promptly. This can be done using the detailed diagnostics within the IRIS-Net PC
software. The source of the fault has to be remedied immediately.
POWER-LED
This LED is permanently green when the N8000 is powered
on. If the ON indication is not illuminated, even though the
device is switched on, this device may not be connected to
the power supply system or the primary fuse may be faulty.
USB Interface
A PC can be connected at the front panel via the USB
interface. Thus, it is possible to connect the N8000 with a
PC even it is already installed - i.e. when the Ethernet
interface at the rear panel is perhaps no longer accessible.
Via the USB interface the network parameters of the N8000
can be edited and files containing the entire N8000
configuration can be transferred. You can find the necessary USB driver in the subdirectory
\Driver\USB in the IRIS-Net setup directory. Please see chapter Interface description for more
information on technical details concerning the USB interface and the other interfaces of the
N8000 which are described in the following section.
