1. Enter the reset board UUCSS command for this ATM-EI circuit
pack.
2. If the same error persists, replace the ATM-EI circuit pac k.
n. Error Type 1793: LANHO transmit FIFO overflow error (the transmit FIFO
RAM buffers on the circuit pac k overflowed). This most likely indicates a
hardware problem on the ci rcuit pack, bec ause the speed of the
LAN/Packet Bus is much higher than the sp eed of the link connecte d to
the port.
1. Test this ATM-EI circuit pack (test board UUCSS).
2. If Test #598 fails again, replace the ATM-EI circuit pack.
o. Error Type 2049, 2050: the ATM-EI is out of lock with the backplane system
clock.
1. Test this ATM-EI circuit pack (test board UUCSS).
2. If Test #304 fails, follow the repair procedures sugg ested for this
test.
p. Error Type 2305: too many parity errors on data received from t he
LAN/Packet Bus (could be due to packet bus p roblems).
1. Test the ATM-EI circuit pack (test board UUCSS).
2. If Test #598 fails, follow the repair procedures sugg ested for this
test.
3. If the test passes, look for and resolve any PKT-BUS (Packet Bus)
alarms/errors.
4. If there are no PKT-BUS errors and the problem persists, escalate
the problem.
Error Type 2309: packet interface chip (LANHO) malfunctioning.
1. Test the ATM-EI circuit pack (test board UUCSS).
2. If Test #598 fails, follow the repair procedures sugg ested for this
test.
q. Error Type 2561: ATM-EI 2-way Transmission Failure (circuit pack is having
problems creating c onnections to other port networks in the system).
1. Test the ATM-EI circuit pack (test board UUCSS).
2. Follow the repair procedures sug gested for Test #241.
r. Error Type 2817, 2818: DSP test failure detected along the circuit p ath of
the ATM-EI circuit pack.
