The LEDs at the bottom of the Ethernet port display information about Ethernet speed and
activity:
• The green LED shows the Ethernet speed. When Off, it indicates a speed of 10Mbps, and
when On indicates a speed of 100Mbps.
• The yellow LED indicates that activity is taking place.
The RESET button is used to reset the DSTREAM unit when required:
• Press and hold the RESET button until the STATUS LED starts to flash green rapidly. If
you release the RESET button at this point, a normal reboot occurs.
• If you continue to hold the RESET button for 10 seconds more, the STATUS LED flashes
red rapidly. When you release the RESET button after this point, DSTREAM reboots and
enters a recovery mode, which enables you to update firmware.
The ports at the front of the unit are shown in the following figure.

The AUX port is included for future enhancement of the product.
