Troubleshooting

Fan Alarm LED is ON

PROBLEM: One of the chassis in the stack is reporting a fan failure (i.e., the FAN ALM LED of that chassis is on).

A built-in feature shuts off power to the circuit cards if a chassis overheats because of fan failure. If the temperature in the chassis reaches 70°C, power to the cards in the chassis is turned off automatically. Power is turned on when the temperature drops below 60°C.

ACTION: Go to the stack to see which chassis is reporting the fan alarm. To clear the fan alarm, contact your service technician to replace the HotWire 8600 chassis.

SYSTEM ALM LED is ON (on a DSL Card)

PROBLEM: SYSTEM ALM LED is ON and DSL card is inoperative in Slot n

ACTION: 1. Using the HotWire DSLAM software, choose Card Selection from the Main Menu to display the status of each DSL card.

2.If a major alarm is indicated, go to the MCC card and do a card reset.

±Use HotWire DSLAM software to reset the DSL card.

±Go to Configuration/ DSL/Cards/Reset_Slot.

±Refer to the HotWire DSLAM for 8540 and 8546 DSL Cards User's Guide for more information.

3.Remove and reinstall the card.

4.If unable to clear by resetting the card, you may need to replace the card.

DSL Card is Not Working Properly

PROBLEM: DSL card does not appear to be working properly.

ACTION: 1. Make sure the path to the LAN/WAN hub or switch is OK.

2.Check cables to the hub and make sure connection is made properly.

3.Try removing the DSL card from the slot and re-installing the card into another slot.
