NTP- D94 Upgrade STM-N Cards and Spans Automatically
An STM-1 to eight-port STM-1 span upgrade, or an STM-4 to four-port STM-4 span upgrade can only
Note
be performed from Slots 1 to 4 and 14 to 17, because the STM1-8 and STM4-4 card can only be installed
in these slots. Ensure that the STM-1 and STM-4 cards are in these slots before performing a span
upgrade to the STM1-8 and STM4-4. The four STM-1 ports will be sequentially mapped to Ports 1 to 4
on the eight-port STM-1 card. The STM-4 port will be mapped to Port 1 on the four-port STM-4 card.
The only cards that can be upgraded to a MRC-12 card are one-port STM-4 cards or one-port STM-16
Note
cards. The port from the lower-speed card will be mapped to Port 1 on the MRC-12 card.
Before performing automatic Span Upgrade, make sure that the TCC card is not soft resetting or pulled
Note
out and there are no fiber cuts or node power cycles.
Determine the span upgrade you need to perform. Valid span upgrades include:

12-8
You cannot upgrade a four-port STM-4 span. If the ring contains any STM4-4 cards and you
want to upgrade the entire ring, you will have to downgrade the STM4-4 card to a single-port
STM-4 card (which is not possible unless only one port on the STM4-4 card is being used).
Do not upgrade an STM-16 to an STM-64 if you have XC-VXL-2.5Gs installed. The
XC-VXL-2.5G card works only with card speeds up to STM-16.
