Power and LED Tests

Warning

Only trained and qualified personnel should be allowed to install, replace, or service this equipment.

Statement 1030

Warning

During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not directly

touch the backplane with your hand or any metal tool, or you could shock yourself.

Statement 94

Caution Operations that interrupt power supply or short the power connections to the system are

service-affecting.

1.13.2 Power Consumption for Node and Cards

Symptom You are unable to power up a node or the cards in a node.

Table 1-37 describes the potential cause of the symptom and the solution.

1.13.3 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. Table 1-38 describes the possible problem and the solution for optical ports.

Table 1-37 Power Consumption for Node and Cards

Possible Problem Solution

Improper power supply. Refer to power information in the “Install Hardware” chapter of the

Cisco ONS 15310-CL and Cisco ONS 15310-MA Procedure Guide.

Table 1-38 Lamp Test for Optical and Electrical Card LEDs

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.

Complete the “Verify Card LED Operation” procedure on page 1-92.
