Note 
The terms "Unidirectional Path Switched Ring" and "UPSR" may appear in Cisco literature. These terms do not refer to using Cisco ONS 15xxx products in a unidirectional path switched ring configuration. Rather, these terms, as well as "Path Protected Mesh Network" and "PPMN," refer generally to Cisco's path protection feature, which may be used in any topological network configuration. Cisco does not recommend using its path protection feature in any particular topological network configuration.

Warning Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed circuitry could constitute an energy hazard.
Note Card removal raises an improper removal (IMPROPRMVL) alarm, but this clears after the card replacement is completed.
Step 1 Log into the node where you will replace the OC-48 card. If necessary, refer to the Cisco ONS 15600 Procedure Guide for a login procedure.
Step 2 Ensure that the card you are replacing does not carry traffic in a 1+1 group:
a. In the node view, click the Maintenance > Protection tabs.
b. Choose the first group listed under Protection Groups.
c. Verify that the slot number for the card you are replacing does not appear in the Selected Groups list. For example, if you are replacing the OC-48 card in slot 3, make sure that Selected Groups does not contain any entries that start with s3, regardless of the port.
d. Repeat Steps b and c for each protection group.
e. If any of the groups contain a port on the card you want to replace, perform the "Force-Switch 1+1 Ports" task.
Step 3 Ensure that the card you are replacing does carry path protection circuit traffic.
Note A port can be part of a 1+1 protection group or part of a path protection, but it cannot be configured for both. However, different ports on one card can be configured in different ways. If you move all of the traffic off some 1+1 ports, you still need to check whether the remaining ports are carrying path protection traffic.
a. In the CTC node view, click View > Go to Parent View.
b. Click the Circuits tab.
c. View the circuit source and destination ports and slots. If any circuits originate or terminate in the slot containing the card you are replacing, perform the "Force-Switch Path Protection Paths" task.
Note If the card you are replacing is not configured for any port or circuit protection, but does carry traffic, bridge and roll this traffic onto another card. Follow the "Bridge and Roll Traffic" procedure in the Cisco ONS 15600 Procedure Guide.
Step 4 Remove any fiber optic cables from the ports.
Step 5 Physically remove the card to be replaced from the ONS 15600 shelf:
a. Open the card ejectors.
b. Slide the card out of the slot.
Step 6 Physically replace the OC-48 card in the shelf:
a. Open the ejectors on the replacement card.
b. Slide the replacement card into the slot along the guide rails until it contacts the backplane.
c. Close the ejectors.
Note When you replace a card with an identical type of card, you do not need to make any changes to the database.
Step 7 Clear the Force switches.
•To clear 1+1 Force switches, complete the "Clear a 1+1 Force Switch" task.
•To clear Path Protection Force switches, complete the "Clear a Path Protection Force Switch" task.
Step 8 Once the card is placed in service and is receiving traffic, reset the card's physical receive power level threshold in CTC:
a. Double-click the newly installed card in CTC node view.
b. Click the Provisioning > Threshold tabs.
c. Click the Physical radio button.
d. Click Set OPM for each port on the card.
