POWER OK LED
Under normal operating conditions, the
POWER OK
LED remains green
while the NI 1450 is powered on. A green
POWER OK
LED indicates that
NI 1450 main power is receiving power and that the NI 1450 is not in a fault
state. A red
POWER OK
LED indicates that the NI 1450 has shut down
because of a fault state. A fault state occurs when the user shutdown input
is asserted, the processor overheats, or the watchdog timer expires.
Note
The
POWER OK
LED does
not
indicate the status of the isolated power, Viso.
STATUS LED
The orange
STATUS
LED remains off under normal operating conditions
and flashes a specific number of times to indicate error conditions or certain
DIP switch settings. The
STATUS
LED remains lit if the NI 1450 detects
an internal error.
Refer to the
for information about LED error indications.
ACT/LINK LED
The orange
ACT/LINK
LED blinks when the NI 1450 receives data from
or transmits data to the network through the Ethernet connection. Unrelated
network activity causes this LED to blink occasionally even when the
NI 1450 is inactive.
Figure 3-2 shows the location of the
ACT/LINK
LED on the NI 1450.
100 Mbps LED
The green
100 Mbps
LED is lit when the network provides 100 Mbps
support and the NI 1450 is communicating at 100 Mbps. If the
100 Mbps
LED is not lit, the NI 1450 is not operating at 100 Mbps.
Figure 3-2 shows the location of the
100 Mbps
LED on the NI 1450.
