8-280 Issue 1 May 2002
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 UUCSS command; 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.
3. If it does the problem is off-board.
4. 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 (reset board UUCSS).
2. If the error persists, replace the board.
The board cannot communicate with the ATM switch.
1. Busyout the board (busyout board UUCSS).
2. Test the board (test board long UUCSS).
3. If Test #1260 fails, replace the board.
4. If Test #1260 passes, make sure the ATM address on both the
S8700 Multi-Connect 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.
an on-board fault.
a faulty data received on one of the circuit pack's external ports.
