Hardware Trouble Indicators
Indications that a module has a hardware problem include the following:
• Failure to power up
• Noisy fans
• Loss of network connectivity
• Battery, temperature, voltage, or power monitoring sensor alerts
• Hard drive failures
•USB media failure
• Physical damage caused by dropping, water, or other external stress
When these kinds of problems occur, inspect the damage caused, and then
try to correct the problem using these strategies:
• Reseat the module and restart it
• Try inserting the module into a different bay in the chassis
• Try replacing hard drives or USB keys
• Reconnect or replace the power and network cables
If these steps do not correct the problem, consult the Hardware Owner’s
Manual for specific troubleshooting information for the hardware device.
