ATM-TRK (Circuit Emulation Service Circuit Pack)
Issue 1 May 2002
8-281555-233-143
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 UUCSS
b. reset board UUCSS
c. test board UUCSS long
d. release board UUCSS
2. If the problem persists and there are no PKT-BUS or port alarms,
replace the circuit pack.
k. Error Type 1538: The ATM-TRK circuit pack is hyperactive (sending an
abnormal number of control messages to the processor). Use the following
command sequence for this ATM-TRK circuit pack:
1. busyout board UUCSS
2. reset board UUCSS
3. test board UUCSS long
4. release board UUCSS
5. If this error persists, replace the circuit pack.
l. Error Type 1794: LANHO transmit FIFO overflow. The circuit pack’s
transmit buffers have overflowed.
1. Run test board UUCSS r 5.
m. Error Type 2049: ACL Link Failure (link is down). The ATM Control Link
(ACL) has failed, communication has been interrupted between the server
and the ATM-TRK circuit packs on the system, and signaling-group
parameters are not communicated across the packet bus.
1. Check the ‘‘PKT-BUS (Packet Bus)’’ on page 8-1230 and
‘‘SYS-LINK (System Links)’’ on page 8-1533 MOs, and follow the
repair procedures indicated.
2. Run test board UUCSS against the ATM-TRK circuit pack.
If Then
Test #598 fails Replace the circuit pack.
If Then
Test 598 fails. Follow the repair procedures suggested for that
test.
