Chapter 12 Upgrade Cards and Spans
NTP- D94 Upgrade STM-N Cards and Spans Automatically
Note An STM-1 to eight-port STM-1 span upgrade, or an STM-4 to four-port STM-4 span upgrade can only
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.
Note The only cards that can be upgraded to a MRC-12 card are one-port STM-4 cards or one-port STM-16
cards. The port from the lower-speed card will be mapped to Port 1 on the MRC-12 card.
Note Before performing automatic Span Upgrade, make sure that the TCC card is not soft resetting or pulled
out and there are no fiber cuts or node power cycles.
Step 1 Determine the span upgrade you need to perform. Valid span upgrades include:
• Four-port STM-1 to eight-port STM-1
• Single-port STM-4 to four-port STM-4
• Single-port STM-4 to STM-16
• Single-port STM-4 to STM-64
• Single-port STM-4 to MRC-12
• Single-port STM-4 to STM-16 on MRC-12
• STM-16 to STM-64
• STM-16 to MRC-12
• STM-16 to OC192SR1/STM64IO Short Reach or OC192/STM64 Any Reach
• STM-64 to OC192SR1/STM64IO Short Reach or OC192/STM64 Any Reach
Note 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).
Note 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.
Valid card upgrades include:
• Single-port STM-4 to STM-16
• Single-port STM-4 to STM-16 on MRC-12
• Single-port STM-4 to STM-64
• Single-port STM-4 to MRC-12
• STM-16 to STM-64
• STM-16 to OC192SR1/STM64IO Short Reach or OC192/STM64 Any Reach
