NOTE:
If there is a DCC failure, a remote login to the shelf connected through
the Source Address cannot be done. The rtrv-alm,
rtrv-map-network, and rtrv-map-neighbor commands can be
used to check for dcc failure for main. Also, use rtrv-fecom command
to see if "fecom" has been disabled.
Note Source Address of DCC channel failure. Check optical fibers
connected through the Source Address per local procedures. If no trouble
found, replace near-end OLIU first then far-end OLIU.
