Reset Test (#889)
The reset action initializes the Packet Interface and causes the Packet Interface
firmware on the TN2401/TN794 NetPkt circuit pack to run a comprehensive set of
diagnostic tests.
The demand reset action aborts if the specified Packet Interface is on an active
SPE (versus a standby SPE) and if that Packet Interface is in the in-service state.
A Packet Interface is put in the out-of-service state automatically if it has been
reset 4 times by background maintenance within the last 15 minutes, independent
of the results of the reset action.
If the system is equipped with the High Reliability or Critical Reliability
Configuration and if the Packet Interface is on the standby SPE, the demand reset
action runs independently of the service state of the Packet Interface.
2 FAIL No response from the active Packet Interface to a request to
the Packet Interface on the active SPE for peer link setup
between the active and standby Packet Interfaces.
1. Retry the test command after a one minute delay.
2. If the test continues to fail:
a. Use the display alarms command to display the active
alarms. Verify that there are no alarms on the standby
SPE components other than the alarm for the Peer Link
failure. If there are, clear those alarms first.
b. Initiate an SPE interchange by moving the SPE
SELECT switches on the DUPINT circuit packs to the
position corresponding to the carrier location of the
standby SPE. This will cause an SPE interchange using
a WARM restart. Established calls will not be
disconnected.
c. Replace the TN2401/TN794 NetPkt circuit pack on the
standby SPE and restore the SPE SELECT switches to
their neutral position.
PASS The SPE is able to communicate with the Packet Interface. If
problems are still reported, check for errors on the Private
Looparound Tests (#885) and Maintenance Looparound Tests
(#886).
