2. Before beginning this procedure, verify ring integrity and path
protection switching function. At the start node, remove the
receive (IN) fiber from ONE of the MAIN OLIUs. Verify no critical
(CR) alarms are present. Reconnect the fiber and wait until
alarms clear. Repeat this step on the other MAIN OLIU.
3. Notify maintenance center that alarms will be generated.
4. Use rtrv-map-network: and rtrv-map-neighbor:
commands to determine the configuration of the OC-3 ring being
upgraded and how the individual nodes are connected.
5. Upgrade all FiberReach nodes to TARP Release 4 software.

CAUTION:
Sync autoconfiguration must be enabled at each line-timed
node in the network.
At each line-timed node in the network, use
set-oc3:syncmsg=
Kbyte/Sbyte
command to enable Kbyte
or Sbyte sync messaging. Use set-sync:auto=
enabled
command to enable Sync auto-reconfiguration.
7. At the starting OC-3 Node (Node 1 in this example), 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.
8. Remote login to Node 2 and 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.
9. Use the rtrv-sync; command to verify that MAIN-2 is the
active circuit pack, and active reference/line.
10. Use the switch-sync:s=src; and
switch-sync:s=circuitpack; to force timing to MAIN-2.
