2. Troubleshooting System Failures

2.2Troubleshooting for IP8800/S3600 and IP8800/ S2400

2.2.1Troubleshooting Procedure on System Failures

Follow the procedure below when the system failed.

Table 2-3: Troubleshooting System Failures

No.

Failure

 

Action

 

 

 

1

• Fume generated from the system

Execute the steps below immediately.

 

• Unusual odor occurs from the system

1.

Power off the system.

 

• Unusual sound occurs from the system

2.

Remove the power cable of the system.

 

 

After the above steps, replace the system.

2

login prompt is not displayed

1.

When MC is inserted, first remove the MC then reboot the system by

 

 

 

turning it off and on.

 

 

2.

When MC is not inserted, reboot the system by turning it off and on.

 

 

3.

If the same problem still persists after system reboot, replace the

 

 

 

system.

 

 

 

3

PWR LED on the system is OFF

Follow the steps below to take the action.

 

 

1.

Follow the steps in "Table 2-4: Isolating Power Supply Failure"

 

 

2.

For the redundant power model, replace the power supply that has

 

 

 

failed. The faulty power supply is in one of the states below.

 

 

 

(a) POWER LED is off.

 

 

 

(b) ALM1 LED is lit in red.

 

 

 

(c) ALM2 LED is lit in red.

 

 

3.

If 1 and 2 are not applicable, restart the system and confirm that the

 

 

 

environment is free from troubles.

 

 

 

(1) Turn off the power switch on the system (or power supply for the

 

 

 

redundant power model) and turn it on again to restart the system.

 

 

 

(2) If the system can be restarted, execute the show logging

 

 

 

command to view the failure information.

 

 

 

>show logging grep ERR

 

 

 

(3) If a message "Caution, High temperature" exists in the retrieved

 

 

 

failure information, the operating environment may have caused the

 

 

 

failure. Request the system administrator to improve the

 

 

 

environment.

 

 

 

(4) If the system cannot be restarted by procedure (1) above and no

 

 

 

failure information exists in procedure (3) above or message

 

 

 

"Caution, High temperature" does not exist, the system may have

 

 

 

failed. Replace the system.

 

 

 

4

ST1 LED on the system is lit in red

A failure occurred or the system was powered on after it had remained

 

 

powered off for a long time (at least one month).

 

 

1.

If you do not turn on the power of the system for a long time (one month

 

 

 

or more), reboot the system by turning it off and on.

 

 

2.

In the case of other than the previous case, a failure might occur in the

 

 

 

system. Replace the system.
