18. Connect each of the cables to the other port (the one to which the other cable
was originally attached). The following will now be true:
v The cable originally connected to port 0 will now be connected to port 1.
v The cable originally connected to port 1 will now be connected to port 0.
Attention: You must fully connect the cable and tighten the connector's
screws within 30 seconds of when the cable makes contact with the port. If
you do not the link will fail and you must disconnect and reconnect again. If
the connector screws are not tightened errors will occur on the link and it will
fail.

function to the frame and port pair that you recorded as the second failing
resource in column 'A'. In column 'B' record the port status for the same
two HSL ports on the second failing resource.
21. Determine what to record for all the rows of column 'C' by performing the
following:
v For the port status in column 'C', compare the port status that you recorded
in column 'A' to the port status you that recorded in column 'B'. If the
port's status is "Failed" in both column 'A' and column 'B,' then mark in the
same row of column 'C' the letter "X" otherwise, leave this row in column
'C' blank.
22. Refer to the information that you recorded in the "Appendix G. HSL Link
Status Diagnosis Form" on page 967.
