Troubleshooting your DSTREAM unit
Your DSTREAM unit indicates any problems using various LEDs.
Perform these basic checks before looking at the more in-depth problems.
Procedure
1. Ensure all the cables are connected and seated properly.
2. Observe the progress of the boot sequence to confirm that your DSTREAM unit is booting properly.
3. Fix the problem indicated by the LEDs on the unit:
•
If the STATUS LED flashes red, it signifies that a boot failure has occurred.
•
If the Dynamic Host Configuration Protocol (DHCP) LED illuminates red when an Ethernet cable
is connected and the link light on the Ethernet socket illuminates, it indicates that the unit has
failed to obtain an IP address.
The DHCP LED is accessible through the access panel on the underside of the unit.
