1.12.3 Lamp Tests for Card LEDs
Symptom Optical (OC-N) ports LEDs do not light, or you are unsure whether the LEDs are working
properly.
The LED lamp test determines whether card-level LEDs are operational. For optical ports, this test also
causes port-level LEDs to turn on. For Ethernet cards, only card-level LEDs light. For these cards,
port-level LEDs can be compared to the given guidelines to determine whether they are working
correctly.
Optical port LEDs light during the lamp test. Ethernet cards only illuminate card-level LEDs during the
test. Tabl e 1-36 describes the possible problem and the solution for optical ports.

Verify Card LED Operation

Step1 In CTC, click the Maintenance > Diagnostic tabs.
Step2 Click Lamp Test.
Step3 Watch to make sure all the port LEDs illuminate as previously noted for several seconds.
Step4 Click OK on the Lamp Test Run dialog box.
With the exceptions previously described, if an OC-N or DS-N LED does not light up, the LED is faulty.
Return the defective card to Cisco through the RMA process. Contact Cisco TAC at
http://www.cisco.com/tac or 1-800-553-2447.

Possible Problem Solution
Faulty optical port LED A lamp test verifies that all the port LEDs work. Run this diagnostic test as
part of the initial system turn-up, a periodic maintenance routine, or any time
you question whether an LED is in working order.
