Chapter 12 Upgrade Cards and Spans
NTP- D95 Upgrade Optical Spans Manually
Caution If you want to upgrade all of the spans in a ring, determine if there are any four-port STM-4 cards in the
ring. If the ring contains any STM4-4 cards and you wish to continue with the upgrade, 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 Optical card transmit and receive levels should be in their acceptable range as shown for each card in
Table 2-4 on page 2-17.
Note In this context the word “span” represents the optical path between two nodes. The words “span
endpoint” represent the nodes on each end of a span.
Note If any of the cross-connect cards reboot during the span upgrade, you must reset each one when the span
upgrade procedure is complete for all the nodes in the ring.
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
• STM-16 to STM-64
• STM-64 to OC192SR1/STM64IO Short Reach or OC192/STM64 Any Reach
Note Do not upgrade an STM-16 to an STM-64 if you have XC-VXL-2.5Gs installed. The
XC-VXL-2.5G works only with card speeds up to STM-16.
Step 2 Complete the “DLP-D60 Log into CTC” task on page 17-49. If you are already logged in, continue with
Step 3.
Step 3 Ensure that no alarms or abnormal conditions (regardless of severity), including LOS, LOF, AIS-L, SF,
SD, and FORCED-REQ-RING are present. See the “DLP-D298 Check the Network for Alarms and
Conditions” task on page 19-83 for instructions.
Note During the upgrade/downgrade some minor alarms and conditions display and then clear
automatically. No service-affecting alarms (SA, Major, or Critical) should occur other than
MSSP-OSYNC, which will clear when the upgrade/downgrade of all nodes is complete. If any
other service-affecting alarms occur, Cisco recommends backing out of the procedure. A
four-node MS-SPRing can take up to five minutes to clear all of the MSSP-OSYNC alarms.
Allow extra time for a large MS-SPRing to clear all of the MSSP-OSYNC alarms.
