j. Error Type 1537: LANHO bus timeout. The circuit pack is transmitting too
many bytes on the LAN bus for a single frame. This can be due to:
■
an on-board fault.
■
a faulty data received on one of the circuit pack’s external ports.
If the error occurs 3 times in 10 minutes, the board is isolated from the
Packet Bus and the board is alarmed. To clear the alarm:
1. Restore this circuit pack to the Packet Bus with this command
sequence:
a. busyout board UUCSS
a. reset board UUCSS
a. test board UUCSS long
a. release board UUCSS
2. If the problem persists and there are no PKT-BUS or port alarms,
replace the circuit pack.
k. Error Type 1538: The ATM-TRK circuit pack is hyperactive (sending an
abnormal number of control messages to the processor). Use the following
command sequence for this ATM-TRK circuit pack:
1. busyout board UUCSS
2. reset board UUCSS
3. test board UUCSS long
4. release board UUCSS
5. If this error persists, replace the circuit pack.
27 SIGCON_DOWN
ATM switch high
level signal. The board cannot communicate with the ATM switch.
Busyout the board (busyout board UUCSS).
Test the board (test board long UUCSS).
If Test #1260 fails, replace the board.
If Test #1260 passes, make sure the ATM address on both the
DEFINITY and the ATM switch sides are the same for this board.
If the address is the same, change the port on the ATM switch side.
If the error is resolved, the problem is on the ATM switch port.
