ICSU Status LEDs Test (#1227)
The TN464F UDS1 circuit pack has four status LEDs on the faceplate in ad dition
to the three standard facep late LEDs. These four status LEDs are associated with
the 120A1 Channel Service Unit (CSU) Module that can b e connected to the
TN464F board via the I/O connector p anel on the back of the port c arrier. The
TN464F circuit pack comb ined with the 120A1 CSU Module forms an Integ rated
CSU (ICSU).
This test is a visual test. It will light the four status LEDs red for 5 secon ds, then
light them green for 5 second s, then light them yellow for 5 second s, then turn
the LEDs off and returns control of the status LEDs to the circu it pack.
This test will only be executed on TN464F or later suffix UDS1 circuit p acks
administered for 24-channel op eration (1.544 bit rate).
If the 120A1 CSU Module is not physically in stalled, the status LEDs are always
off and this test will abort.
PASS The active long-duration loopback or span test on the TN464F circuit pack
was successfully terminated.
0NO
BOARD The test could not relate the internal ID to the port (no board). This could be
due to incorrect translations, no board is inserted, an incorrect board is
inserted, or an insane b oard is inserted.
1. Ensure that the board translations are correct. Execute the add ds1
UUCSS command to admini ster the UDS1 interface if it is not alread y
administered.
2. If the board was already administered correctly, check the error log to
determine whether the board is hyperactive. If this is the case, the board
is shut down. Reseating the b oard will re-initialize the board .
3. If the board was found to be correctly inserted in step 1, then issue the
busyout board command.
4. Issue the reset board command.
5. Issue the release busy board command.
6. Issue the test board long command.
This should re-establish the linkage between the internal ID and the port.
