A router software failure was detected. When this error occurs, this

 

 

 

 

 

pattern of LEDs appears for only a few seconds until the router

 

 

 

 

 

reboots (which will occur unless Auto Reboot in the configuration

 

 

 

 

 

has been disabled). If Auto Reboot has been disabled, reset the

 

 

 

 

 

router module to reboot it.

 

 

 

 

 

After the router reboots, information about the failure will appear in

 

 

 

 

 

the crash history (which can be displayed using the NCL Crash

 

 

 

 

 

command) and in the event log (which can be displayed from the

 

 

 

 

 

Main menu).

1. Verify that the node at the other end is up and running.

 

 

 

 

 

2. If this error persists, make sure the WAN is specified correctly in

 

 

 

 

 

the configuration. (Refer to “Create or Modify a Router

 

 

 

 

 

Configuration”, page 2-5.)

 

 

 

 

 

3. If the error still persists, check for a fault in the network equipment

 

 

 

 

 

or links.

 

 

 

 

 

4. If the error still persists, replace the WAN cable.

 

 

 

 

 

5. If the error still persists, replace the router module.

Either a device has not yet been connected, or the connection to the

 

 

 

 

 

remote device has been lost. The broken connection can be

 

 

 

 

 

detected if the Remote signal & sense parameter is enabled in the

 

 

 

 

 

configuration or if a protocol is running on this port. The circuit will

 

 

 

 

 

be enabled again when the connection is restored.

 

 

 

 

 

For point-to-point non-X.25 circuits, if Remote signal & sense is

 

 

 

 

 

enabled, then the WAN port is not hearing properly addressed

The router module’s LAN driver is unable to send data. (Data is sent

 

 

 

 

 

by a protocol or when XCVR Signal Polling is enabled on the internal

hardware, excessive collisions, or excessive deferrals. Call for

 

 

 

 

 

service from your HP dealer or service provider.
