Expansion Interface Test (#244)
This test is potentially very destructive and requires the EI circuit pack to be
busied out prior to execution of this test.
The Expansion Interface test, which is not a part of either the short or long test
sequences, is executed via the reset board PCSS command where PCSS is the
address of the EI circuit pack to be reset.
ANY FAIL The transmitted data packet was not received correctly by the Packet Interface
circuit pack. The failure may be in the EI under test, the DS1 CONV circuit
packs, or the intervening Center Stage components.
1. Test the Packet Interface circuit with the test packet-interface CS
command where “C” is the IPSI’s carrier in a high- or critical-reliability
system, and “S” is the slot number where the IPSI’s Packet Interface
resides. If the Packet Interface circuit fails any tests, see‘‘PKT-INT (Packet
Interface)’’.
2. If the EI under test resides in a high-reliability system’s PN, (2 PN-to-CSS
fibers in an unduplicated PNC), run the short test sequence on both of the
PN’s EI boards, and follow procedures for Test #589.
3. Enter display errors and resolve any PKT-BUS errors.
4. Perform the ‘‘Fault Isolation for Fiber Links’’.
PASS Although this test has passed, there may be related problems on other EIs used
in connectivity to and from this EI. Software may have conducted tests on these
other components and determined that this board was functioning properly and
any problems were probably due to a problem with some other connectivity
component. Check the error and alarm logs for problems with other EI circuit
packs and resolve these errors.
1. Refer to other EI board tests if the link is not functioning correctly.
0NO
BOARD
No board was detected by the test.
1. Resolve either wrong board (Error 125) or no board (Error 131) issues.
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.
