5.0 Switch and LED Indicator Functions
5.1 Switch Functions
The Configure pushbutton takes the DLPCIe out of On-Line operation mode and puts it in the
BIOS Manager mode. The BIOS Manager mode also allows for configuration parameters to be
downloaded from or uploaded to the Windows based configuration software (EQ32). When this
mode has been entered the STATUS LED will be RED and BUS LED will be Green while NET
LED will be off. To put the unit back On-line use option 7 from the BIOS menu or can power
off then on the PC.
5.2 Indicator Functions
5.2.1 Power-Up and Reset Sequence
On Power-up the DLPCIe executes a self diagnostic check-up or the ram and flash firmware.
The correct LED indicator sequence to show the DLPCIe is functioning properly is as follows:
After all LEDS go out.
LED STATUS
STATUSLED RED for 0.5 seconds
BUSLED Green for 0.5 seconds
NETLED Green for 0.5 seconds
After this sequence the DLPCIe goes into the On-line mode of Operation. The LED indicators
will behave in the certain way defined by the DLPCIe model used. Most likely all LEDS will be
off waiting for communication on its channels.
