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.

Indicators
SD LED
Color
Description
Blue
The blue SD LED indicates a signal degrade or condition such as a low
level signal on at least one of the card’s ports.
SF LED
Red
The red SF LED indicates a signal failure or condition such as LOS,
LOF, or high BERs on at least one of the card’s ports. The red SF LED
also illuminates when the transmit and receive fibers are incorrectly
connected. When the fibers are properly connected, the LED turns off.
Warning
Invisible laser radiation may be emitted from the end of the unterminated fiber cable or connector. Do
not stare into the beam or view directly with optical instruments. Viewing the laser output with
certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance
of 100 mm may pose an eye hazard. Use of controls or adjustments or performance of procedures other
than those specified may result in hazardous radiation exposure.

Warning
Note
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.
Card removal raises an improper removal (IMPROPRMVL) alarm, but this clears after the card
replacement is completed.
Step 1
Step 2
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.
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.
e. If any of the groups contain a port on the card you want to replace, perform the “Force-Switch 1+1

Replace an OC-48 Card
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
Step 5
Remove any fiber optic cables from the ports.
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
Step 8
Clear the Force switches.
•
•
To clear Path Protection Force switches, complete the “Clear a Path Protection Force Switch” task
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.

Web Site and the Cisco TAC Escalation Center.
Inquiries to Cisco TAC are categorized according to the urgency of the issue:
•
•
•
•
Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities,
product installation, or basic product configuration.
Priority level 3 (P3)—Your network performance is degraded. Network functionality is noticeably
impaired, but most business operations continue.
Priority level 2 (P2)—Your production network is severely degraded, affecting significant aspects
of business operations. No workaround is available.
Priority level 1 (P1)—Your production network is down, and a critical impact to business operations
will occur if service is not restored quickly. No workaround is available.
Which Cisco TAC resource you choose is based on the priority of the problem and the conditions of
service contracts, when applicable.
