Troubleshooting

This chapter provides information about product issues in the Cisco 600 series

CPE.

WAN Link and Power-Up Issues

When you power up the CPE, this is the normal sequence of events:

•

The ALARM light comes on within 5 seconds, flashes for half a second, then

goes off.

•

Between 1 and 10 seconds after the ALARM light goes off, the WAN-LNK

light starts blinking, indicating that the CPE is attempting to establish

communication with the central office equipment. After communication is

established, the WAN-LNK becomes solid.

So under normal conditions, the ALARM light should be off within six seconds

of powering up the CPE, and within one minute the WAN-LNK light should

become solid.

If the CPE cannot establish communication with the service provider equipment,

the WAN-LNK light will go off and the CPE will wait 10 seconds. The

WAN-LNK light will start blinking when the CPE tries again to establish

communication.

If, after repeated attempts to establish communication, the WAN-LNK light

continues blinking, turn the power off and then on. If the WAN-LNK light still

does not become solid within one minute, call your service representative.
