9-180ATM-EI (Expansion Interface Circuit Pack)
9
l. Error Type 1537: LAN bus time out. The circuit pack is transmitting a
packet larger than 1,024 b ytes. Replace the circ uit pack.
m. Error Type 1538: A hyperactive ATM-EI circuit pack is generating an
abnormal amount of control messag es to the processor. When this error is
generated, the system automatic ally resets the ATM-EI.
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 indicate s 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 connec ted 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 the
LAN/Packet Bus (could be d ue to packet bus problems).
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.
Duplicated PNC? Then:
Y service to the EPN is disrupted
N the system switches to the standby PNC
