36.
NOTE:
A CP removed alarm will occur when the OLIU is removed.
An inc. OC12 LOS (blinking FAULT LED on OLIU) alarm
will occur at the other node connected to the removed fibers.
Other nodes will receive inc. VT AIS and inc.
STS AIS alarms.
At Node 4, remove optical fibers and lift the faceplate latch of
MAIN-1 OLIU, then remove MAIN-1 OLIU.
37.
NOTE:
When the 29-Type OLIU is installed in this step, an
unexpected CP type status alarm will occur. When fibers
are reconnected, the inc. OC12 LOS alarm will clear at
the connecting Node.
At Node 4, install a 29-Type OLIU into MAIN-1 OLIU slot and
reconnect optical fibers.
38. At Node 4, switch STS-1 and/or VT1.5 path from MAIN-2 to
MAIN-1 with the switch-path-sts1: and/or
switch-path-vt1: commands.
39. Use the
rtrv-sync;
command to verify that MAIN-2 is the
active circuit pack, and active reference/line.
40. Use the
switch-sync:s=src;
and
switch-sync:s=circuitpack;
to force timing to MAIN-2.
41. At the starting Node 1, switch STS-1 and/or VT1.5 path from
MAIN-1 to MAIN-2 with the switch-path-sts1: and/or
switch-path-vt1: commands.
