PASS When this test (#242) and the EI Local Looparound test (#240) pass, this
indicates that the EI board is functioning properly, but it does not verify that the
optical portion of the lightwave transceiver is functioning.
1. Issue the test board UUCSS command on the EI board on both ends of
fiber. If this test passes from both sides, but other tests fail, such as #241,
this condition indicates either a faulty lightwave transceiver or the fiber
itself has failed. To determine whether a lightwave transceiver or the fiber
itself has failed, execute the EI Manual Loop-Back procedure described in
a previous section.
NOTE:
Test #242 can only be run from both EIs if they are the standby pair and
the active pair is working properly.
2. If this EI board is failing other tests, execute the EI Manual Loop-Back Test.
3. If problems still exist after the EI Manual Loop-Back Procedure indicates
both EI boards and both lightwave transceivers are healthy, manually
check out the building fiber. Verify that each optical fiber connects to a
transmitter at one end and a receiver at the other.
0NO
BOARD
No board was detected by the test.
1. Check the error log for wrong board (Error 125) or no board (Error 131).
Resolve either of these issues, if applicable.
2. Check that the board is properly translated and inserted. If so, check for
hyperactivity (Error 1538). If hyperactive, use the reset board UUCSS
command.
3. Run the test again. If it fails, the ID chip on board may be bad. Replace
the board and retest.
