The System Status LEDs indicate the unit's operational status:
LED Display
Status Description
Power is correctly supplied to the unit (+5 V present on the D400 Main
Board).
Initialization (boot-up and self-diagnostics) of the D400 is complete and the
unit is ready to process data.
IRIG-B signal is being correctly processed. This LED flashes at a 1 Hz rate.
Link integrity for the Ethernet Switch in NET1 and NET2 slots. See note below.
Transmission activity for the Ethernet Switch in NET1 and NET2 slots. See
note below.
The NET2 ACT/LINK LEDs on the front panel may not be properly driven on the D400 Main
Module with FPGA revision V1.4 and earlier when using the Redundant TP Ethernet + COM2
Port card (GE Item No. 520-0218LF). To check the FPGA revision, enter dmesg -s 16392 |
grep -i FPGA at the D400 command prompt and search for FPGA in the output.
The Serial Port Status LEDs provide a visual indication of the status for each serial
communication port. For a given serial communication port:
LED Display
Status Description
TXD
Serial transmission activity on the serial port
RXD
Serial reception activity on the serial port
If a pair of LEDs is not lit, it does not indicate a problem, only that the connected device is
not active at that moment.
If a serial communication card slot is empty, (that is, no card is installed) the serial Receive
(RXD) LED may be lit.
The D400 includes a built-in HMI (human machine interface). The HMI is your window into
the D400. Through the HMI you can monitor the status of your substation network, view
data, execute control commands, configure devices and SCADA masters, and change the
system set-up.
