Repair procedure
The far end is detecting a major problem with the signal that this
board is transmitting. The transmitted payload is invalid.
1. Make sure the ATM switch port (or a MUX port, if present
between ATM switch and the ATM-TRK board) is the same as the
ATM-TRK circuit pack’s cable interface.
2. Run test board location.
If Test #1259 fails with Error Code 23, connect a fiber
back-to-back in a looped mode (one strand of fiber connecting
the transmit transceiver to the receive transceiver of the
board) and see if the amber LED flash goes away.
● If it does the problem is off-board.
● If the amber LED continues to flash, replace the circuit
pack.
On board ATM framer chip is not able to frame cells based on the
cell header.
1. Reset the board with reset board location.
2. If the error persists, replace the board.
The board cot communicate with the ATM switch.
1. Busyout the board (busyout board location).
2. Test the board (test board long location).
3. If Test #1260 fails, replace the board.
4. If Test #1260 passes, make sure the ATM address on both the
server and the ATM switch sides are the same for this board.
5. If the address is the same, change the port on the ATM switch
side.
6. If the error is resolved, the problem is on the ATM switch port.
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 three 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 location
b. reset board location
c. test board location long
