ATM-EI (Expansion Interface Circuit Pack)
Issue 1 May 2002
8-201555-233-143
1. Enter the reset board UUCSS command for this ATM-EI circuit
pack.
2. If the same error persists, replace the ATM-EI circuit pack.
n. Error Type 1793 — LANHO transmit FIFO overflow error (the transmit
FIFO RAM buffers on the circuit pack overflowed). This most likely
indicates a hardware problem on the circuit pack, because the speed of the
LAN/packet bus is much higher than the speed of the link connected 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 Types 2049 and 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 suggested for this
test.
p. Error Type 2305 — Too many parity errors on data received from the
LAN/packet bus (could be due to packet-bus problems).
1. Test the ATM-EI circuit pack (test board UUCSS).
2. If Test #598 fails, follow the repair procedures suggested 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 — The packet-interface chip (LANHO) is malfunctioning.
1. Test the ATM-EI circuit pack (test board UUCSS).
2. If Test #598 fails, follow the repair procedures suggested for this
test.
q. Error Type 2561 — ATM-EI 2-way transmission failure (circuit pack is
having problems creating connections to other EPNs in the system).
1. Test the ATM-EI circuit pack (test board UUCSS).
2. Follow the repair procedures suggested for Test #241.
