ATM-TRK (Circuit Emulation Service Circuit Pack)
Issue 1 May 2002
8-283555-233-143
q. Error Type 3330: LANHO critical error. The circuit pack reports that the
on-board LANHO chip is insane (possibly due to a problem in packet-bus
arbitration, in the transmission line frame, or in the circuit pack itself). The
circuit pack cannot talk to the packet bus.
1. Check for PKT-BUS alarms.
r. Error Type 3585: Major board alarm; failure of critical components
involved in the operation of the circuit pack. The circuit pack has failed,
and the switch can no longer recognize it.
If Then
There is a
packet-bus alarm
There is probably a packet-bus problem,
particularly if other circuit packs on the packet bus
report the same error. See ‘‘PKT-BUS (Packet
Bus)’’ and ‘‘Isolating and Repairing Packet-Bus
Faults’’ for repair procedures.
There are no
packet-bus
alarms
Run the following command sequence:
1. busyout board UUCSS
2. reset board UUCSS
3. test board UUCSS long
4. release board UUCSS
The problem
persists
Replace the ATM-TRK circuit pack.
