123 FAIL The SNI circuit pack cannot communicate with its neighbor via the packet path.
1. Fix any on-board errors (SNI-BD, EXP-INTF, and/or DS1C-BD) against the
components of this fiber link by using display errors and display alarms
and following the associated repair procedures. (Use the list fiber-link
command to find the fiber link associated with this SNI. The display
fiber-link command can then be used to find the endpoints of the fiber link
and the DS1C circuit pack locations if this fiber link has a DS1 Converter
complex administered.)
2. Enter display errors and display alarms and follow the associated repair
procedures for any SNC-BD error entries with corresponding on-board
alarm entries.
3. Enter display errors and follow the associated repair procedures for any
SYNC entries.
4. If this FIBER-LK has circuit, packet, and control path errors, check the
lightwave transceiver connections or metallic connections. Use the LED
states to verify whether the connections are correct. Also, a test fiber-link s
command can be run to determine whether a fiber out of frame condition
exists on the fiber link; the SNI Fiber Out-of-Frame Query (#989) reports
whether a fiber out of frame condition exists for an SNI endpoint and the
Expansion Interface Fiber Out-of-Frame Query test (#238) reports whether
a fiber out of frame condition exists for an Expansion Interface endpoint.
5. Replace the lightwave transceivers if present.
6. Replace one of the endpoint boards.
7. Replace the other endpoint board.
8. Replace the DS1 CONV circuit packs if a DS1 CONV converter complex is
administered on this fiber.
PASS The SNI can communicate with the peer SNIs and the neighbor over the packet
path.
0NO
BOARD
No board was detected by the test.
1. Check that board is properly translated and inserted.
2. Run the test again. If it fails, reset the board. An SNI should be reset
instead of reseating the circuit pack. The reset board command should
almost never be used on an SNI. It may be necessary to use the reset
board command if the SNI circuit pack gets into a mode where it cannot
communicate with software. If an SNI with active errors and alarms is
reset, the errors and alarms may take a while to come back, therefore the
reset board command can mask real problems.
3. Run the test again. If it fails, the ID chip on board may be bad. Replace
the board and retest.
