Table 4-1 summarizes the self-test failure codes displayed by the LEDs; these patterns appear when the
Cisco CVA122/CVA122E Cable Voice Adapter has failed to complete a self-test and enters its
diagnostics mode.

If the main memory initialization routine successfully completes, all LEDs turn off.
If all self-tests passed, the cable voice adapter boots the Cisco IOS image stored in its Flash

memory. The Message LED blinks during the boot process and continues blinking until it finishes
booting the Cisco IOS image; after loading the image, the Message LED turns off. If the Message
LED does not start to blink, or if it continues to blink for more than ten minutes, proceed to the
"Troubleshooting Subsystems" section.
The cable voice adapter starts normal operations after it starts up the Cisco IOS image. At this

point, the LEDs indicate the status of the cable voice adapter:

When the cable voice adapter and computer have booted successfully, you should be able to access

an Internet web site, which will confirm that the cable voice adapter is configured correctly. If you
cannot access a web site, proceed to the "PC Subsystem" section on page 4-10.

The cable voice adapter then attempts to clear the BSS area of the DRAM; if this fails, the
Cable Status and Ethernet LEDs light and remain on to indicate a memory or controller
problem. If this test succeeds, the Message LED begins blinking.
Finally, the cable voice adapter attempts to clear the rest of DRAM. If this fails, the Ethernet
and USB LEDs remain on to indicate a possible memory or controller problem.

The Cable Activity LED blinks to indicate activity on the cable interface and remains on
otherwise.
The Ethernet LED goes on solid when the Ethernet interface is properly connected to an
Ethernet network interface card on a PC. The Ethernet LED also blinks to indicate activity on
the Ethernet interface.
The USB LED goes on solid when the USB port is properly connected to a USB port on a PC.
The USB LED also blinks to indicate activity on the USB interface.
The service provider controls the Message LED, which can be used to notify the user of special
events, such as waiting voicemail or email. Contact your service provider for details on this
LED.
