Verifying the Uplink Card Connection
Read the following troubleshooting tips to help verify a successful uplink card connection with the system:
•Verify LED status by checking uplink card LED color. (See all the tables in the "LEDs" section.)
•Verify that the card is fully seated against the midplane.
•Verify that all cables are properly connected.
•Verify that the cable types are correct (RPR card cables, for example, are all single-mode).
•Verify that RX and TX are properly connected.
•Verify that side A and side B are properly connected for SRP.
•Verify that span East and span West are properly connected for the RPR/SRP card.
•Verify that there are no duplicate MAC addresses.
•Check the power source:
–Power switch is turned to the on (-) position.
–Power supply connection is secure.
–DC power is turned on at the circuit breaker.
LEDs
The following LED information is found in this section:
•DPT and POS/DPT Uplink Card LEDs
•RPR/SRP Uplink Card LEDs
DPT and POS/DPT Uplink Card LEDs
Information on both uplink card specific LEDs and system LEDs for the DPT and POS/DPT uplink cards is in this section.
The LEDs located on the left side of the DPT and POS/DPT uplink card provide DPT and POS uplink status information. (See Figure 5-1.) For POS/DPT uplink cards, the LED information is dependent on whether the card is configured as POS or DPT. (See Table 5-1 and Table 5-2.)
See Table 5-3 for system LED information for the DPT and POS/DPT cards.

Troubleshooting the Uplink Cards Installation
Read the following troubleshooting tips to help verify a successful installation of the uplink cards:
•Fiber Misconnection—DPT Uplink Cards
•Fiber Misconnection—RPR/SRP Uplink Card
•Alarm Messages
Fiber Misconnection—DPT Uplink Cards
Check for misconnected fiber cables (Side A to side A, TX to TX, span East to span East, and so forth) using the show srp command. Misconnection Alarm appears at the top of the show srp command output.
•One alarm—Problem is with another node on the ring; for example, side A connected to side A.
•Two alarms—Problem is your node.; for example, side A to side A and side B to side B.
•Ensure that the duplex cables are not misconnected.
Fiber Misconnection—RPR/SRP Uplink Card
Check for misconnected fiber cables (span West to span West or TX to TX, and so forth) using the show rpr-ieee protection command. Misconnection Alarm appears at the bottom of the show rpr-ieee protection command output.
•One alarm—Problem is with another node on the ring; for example, side West connected to side West.
•Two alarms—Problem is your node; for example, span West to span West and span Eastto apan East
•Ensure that the duplex cables are not misconnected.

Troubleshooting the POS Uplink Card Installation
This section provides information for troubleshooting the POS/DPT uplink card installation.
Alarm Processing
The following system alarms are monitored by the POS uplink card and reported to the console port:
•Loss-of-Signal (LOS)
•Loss-of-Frame (LOF)
•Line Alarm Indication Signal (LAIS)
•Line Remote Defect Indication (RDI)
•STS Path Loss-of-Pointer (LOP)
•STS Path Alarm Indication Signal (AIS)
•STS Path Remote Defect Indication (RDI)
•B1 Bit Error Rate (BER) threshold crossing alarm (b1-tca)
•B2 BER threshold crossing alarm (b2-tca)
•B3 BER threshold crossing alarm (b3-tca)
•Line Bit Interleave Parity (LBIP) BER in excess of signal degrade threshold (sd-ber)
•LBIP BER in excess of signal failure threshold (sf-ber)
At any time the status of the SONET/SDH alarm and signal events can be examined using the show controllers command, as shown in the following example:
Router# show controllers pos1/1
LOF = 0 LOS = 0 BIP(B1) = 0
AIS = 0 RDI = 0 FEBE = 0 BIP(B2) = 0
AIS = 0 RDI = 0 FEBE = 0 BIP(B3) = 0
LOP = 0 NEWPTR = 0 PSE = 0 NSE = 0
Alarm reporting enabled for: SF SLOS SLOF B1-TCA B2-TCA PLOP B3-TCA
State: PSBF_state = FALSE
Rx(K1/K2): 00/00 S1S0 = 00, C2 = CF
Remote aps status non-aps; Reflected local aps status non-aps
State: RDOOL_state = FALSE
PATH TRACE BUFFER : STABLE
Remote hostname : RouterB
Remote Rx(K1/K2): 00/00 Tx(K1/K2): 00/00
BER thresholds: SF = 10e-4 SD = 10e-6
TCA thresholds: B1 = 10e-6 B2 = 10e-6 B3 = 10e-6
RX readout values: -6 dBm
Loopback Testing
The POS uplink card supports two loopback modes for network testing, fault isolation, and agency compliance. The uplink card loopback modes are:
Internal loopback mode—Packets sent from the Cisco 10720 Internet Router out of the uplink card POS port TX optics are also looped back into the Cisco 10720 Internet Router.
Line loopback mode—Packets received by the POS uplink card port RX optics and sent into the Cisco 10720 Internet Router are also looped back out of the uplink card port TX optics.
Loopback testing is enabled through software. See the Cisco IOS Software Configuration for the Cisco 10720 Internet Router.
Additional Troubleshooting Resources
For more troubleshooting information for the uplink card, refer to the following publications:
•Chapter 4, "Troubleshooting", in the Cisco 10720 Internet Router Installation and Configuration Guide
•Cisco IOS Software Configuration for the Cisco 10720 Internet Router document
Cleaning the Fiber-Optic Connections
For information about cleaning fiber-optic cable connectors and receptacles, see the Inspection and Cleaning Procedures for Fiber-Optic Connections document. It provides detailed illustrations and photos of procedures and equipment required to properly clean fiber-optic connections.
