If you install STM-64 cards, a disabled STM-64 laser causes an LOS alarm to be reported for
each STM-64 slot. Enable the STM-64 laser by setting the safety key lock on the STM-64

for additional spans in the ring.
The span upgrade process resets the line's CV-L threshold to factory default. The CV-L threshold
is reset because the threshold is dependent on line rate.
This procedure upgrades STM-N speeds within MS-SPRings, SNCPs,
and 1+1 protection groups by upgrading STM-N cards. Complete a
manual upgrade task if you need to perform error recovery for the Span
Upgrade wizard or back out of a span upgrade (downgrade).
Replacement cards
The manual span upgrade procedure requires at least two technicians
(one at each end of the span) who can communicate with each other
during the upgrade.
