mainframe hardware is probably working correctly. This
means that the problem is elsewhere. Do the following to
help isolate where the problem lies.
1. Check the SDN cable to see if it is missing or
defective. If it is, replace or install a new one as
required.
2. Make certain there are not duplicate SDN beds. If
there are, reconfigure the receiver mainframe for
other branches or move one bedside to another
branch.
3. Make certain that two receiver mainframes do not
have identical SDN Unit numbers. If they do,
reconfigure one receiver mainframe with another
SDN unit number.
4. If it is a non-SCC system, an SDC cable may have
been used instead of an LDC cable. Check the cable
to make certain an LDC cable is being used.
5. The breakaway board portion of the SDN board
could be broken. Replace the SDN board.
