NOTE:
If a program installation is being performed to a SYSCTL at the far end, it
is normal for the FAULT LED on the near-end SYSCTL to flash and the
MJ and NE ACTY LEDs to light on the User Panel. If there is a MJ alarm
at the end receiving the program, trouble is indicated. You should check if
a program installation is being done.
Is new software generic being downloaded (program upgrade) to the SYSCTL
at the far end terminal?
If YES, STOP. YOU HAVE COMPLETED THIS PROCEDURE.
If NO, continue with Step 14.
14. In alarm report, is there any indication of OLIU or fiber trouble at near end or
far end such as inc. OC1 FERF, inc. OC3 FERF, or inc. OC12
FERF alarm message?
If YES, continue with Step 15.
If NO, proceed to Step 17.
15.
NOTE:
If there is a DCC failure, a remote login to the shelf connected through
the Source Address cannot be done. The rtrv-alm and
rtrv-map-network or rtrv-map-neighbor command 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.
Reference: DLP-523

reseat the SYSCTL.
18. Is the FAULT LED on the SYSCTL circuit pack still flashing (section DCC
channel failed)?
If YES, continue with Step 19.
