A wire from the power source to the terminal block is faulty.

Test the wire and replace it, if necessary.

The CSP powers up, but some of the three LED indicators on the Power Supply card are flashing.

A fuse on the Power Supply card is blown.

Replace the Power Supply card.

With a redundant system, the problem may be caused by any of the following:

1. A circuit breaker is not ON.

2. A wire from a power source to the terminal block is faulty.

3. A power source is defective.

1. Make sure that all the circuit breakers are on.

2. Make sure that the wires from the power sources to the terminal block are functioning. Replace any faulty wires.

3. Make sure that the power sources are functioning and replace a defective source.

The CSP powers up, but all three LED indicators on the Power Supply card are flashing.

The wiring on the Power Input Panel at the rear of the chassis is incorrect.

Check the wiring on the Power Input Panel. Refer to the section about powering the CSP in the CSP Chassis Installation chapter.

The power switch on the Power Supply card is defective.

Replace the Power Supply card.

The CSP powers up, but then shuts down.

A circuit breaker has been tripped.

Remove all cards except a Power Supply card from the chassis, reset the circuit breaker, and try to power up the CSP again.

If the circuit breaker is tripped, check the wiring. Refer to the section about powering the CSP in the CSP Chassis Installation chapter.

If the circuit breaker is not tripped, plug in the cards one at a time until you find the faulty card.

The thermal switch has shut down the CSP because of overheating.

Make sure that you meet the requirements listed in Pre-"Installation Considerations in the appropriate chapter.

The power source failed or does not provide the required level of voltage and current (–48 V DC/
25 A).

Test the power source to make sure that it’s functioning at the required levels. If the power source is faulty, repair or replace it.

The CSP powers up, but the fans do not.

The fan tray is not seated properly. you must supply sufficient force to seat the tray in the chassis.

Reseat the fan tray by using sufficient force.

The fan tray is defective.

Replace the fan tray.

When you power up the CSP, the LED indicators on the Matrix Controller card do not light up.

The Matrix Controller card is not seated properly.

Reset the card. If the LED indicators do not light up, reseat the card.

The Matrix Controller card is defective.

Replace the Matrix Controller card.

When you power up the CSP, a card’s Halt LED indicator is red.

The card could be defective if the Halt LED indicators on other cards are green.

Reseat and reset the card. If the Halt LED indicator is still red, call Cantata Technical Support.

When you power up the CSP, a card’s LED indicators do not light up.

The card is not seated properly.

Reseat the card.

The card is in the wrong slot.

For example, the Matrix Controller card is in a line card slot or a service card slot; or a line card or service card is in an Matrix Controller card slot.

Make sure that the card is in the right slot. Refer to the Card Installation chapter.

The card does not seat properly.

The card is not properly aligned.

Make sure that the card is properly aligned when you slide it into the chassis.

The card is in the wrong slot.

For example, the Matrix Controller card is in a line card slot or a service card slot; a line card or service card is in an Matrix Controller card slot.

Make sure that the card is in the right slot. Refer to the Card Installation chapter.

The pins on the midplane are bent.

Turn OFF the power to the CSP and try to straighten the bent pins. If you cannot straighten the pins, replace the chassis.

The clock source LED indicators on the Matrix Controller Series 3 card are blinking green indicating there is no clock source.

For External Clock Source

The Reference Clock port on the Matrix Controller I/O Series 3 card is not connected to an external reference clock.

Refer to the Matrix Controller I/O Series 3 card, reference clock information in the Hardware Product Description (HPD) guide.

For Loop Timing

The 25-pair connectors on the
E-ONE/T-ONE card are not connected, so that E-ONE/T-ONE span loop timing is not provided.

The E-ONE/T-ONE card is not configured for loop timing.

Refer to the E-ONE/T-ONE card, 25-pair connector information in the Hardware Product Description (HPD) guide.

Refer to the Developer’s Guide: Overview to configure loop timing.

The Signal Detect LED indicator on the EXNET-ONE card stays red for longer than 10 seconds after you power up the CSP.

The fiber optic cable is not installed.

Install the fiber optic cable.

The fiber optic cable is not seated properly.

Firmly press the fiber optic cable connector into the socket on the EXNET-ONE card.

The fiber optic cable is damaged.

Replace the fiber optic cable.
