Chapter 5: Troubleshooting

Check with the WAN Service Provider to ensure that the circuit has been configured by them and is active.

NOTE

It may be necessary to provide proof of proper configuration of your WAN connection. Service Providers typically require proof that the customer’s equipment is configured correctly before checking their own configuration.

Status (S) LED is OFF

The port is operating normally. If it is not, and this LED is OFF, the port may be disabled. Use management to make sure that the WAN interface on the HSIM-W85 is configured correctly.

Status (S) LED is RED

A RED alarm indicates that the WAN connection is not receiving proper framing or has lost framing from the remote device.

Verify the framing, zero suppression.

Verify the use of proper cabling on the WAN connection.

Status (S) LED is AMBER

The device is in Yellow alarm mode. A Yellow alarm indicates that the HSIM-W85 is receiving proper framing from the Telco, but the Telco is not receiving proper framing.

Check for faulty or incorrect cabling between the Telco and the HSIM-W85.

Request that the Telco verify the configuration and operation of the circuit.

Status (S) LED is GREEN (blinking)

Device is in test mode.

The HSIM-W85 is running its Power-up Diagnostic Tests.

Loopback Testing is underway on a WAN circuit. Loopback testing can be initiated by the Telco.
