Switch and LED Indicator Functions
4.1 Switch
Functions
Reset Pushbutton
The Reset pushbutton will perform a complete hardware reset of the DL4500. It is
identical to a complete power cycle and will cause the DL4500 to go through its LED
start-up sequence as defined in Section 5.2.1.
A complete hardware reset is needed on
changing any online operating parameters.
Configure Pushbutton
The Configure pushbutton takes the DL4500 out of On-Line operation mode and puts it
in the BIOS Manager mode. When this mode has been entered the Ethernet and Status
will be RED and A-B Network will be out. To put the unit back On-line it is necessary to
either press the Reset or cycle the DC power supplied to the DL4500.
4.2 Indicator
Functions
4.2.1 Power-Up and Reset Sequence
On Power-up or after the Reset button has been pressed the DL4500 executes a self
diagnostic check-up or the ram and flash firmware. The correct LED indicator sequence
to show the DL4500 is functioning properly is as follows: After all LEDS go out.
LED
Status
Power
Green Continuously
Status
Green for 0.5 seconds
A-B Network Green for 0.5 seconds
Ethernet
Green for 3 seconds
After this sequence the DL4500 goes into the On-line mode of Operation. The LED
indicators will behave in the certain way defined by the DL4500 model used. Most likely
the A-B Network will be solid or flashing depending on the A-B Network used.
