Troubleshooting Your System
Safety First—For You and Your System
 
WARNING: 
Whenever you need to lift the system, get others to assist you. 
To avoid injury, do not attempt to lift the system by yourself.
 
WARNING: 
Before removing the system cover, disconnect all power, then unplug 
the AC power cord, and then disconnect all peripherals, and all LAN lines.
 
CAUTION: 
Many repairs may only be done by a certified service technician. 
You should only perform troubleshooting and simple repairs as authorized in 
your product documentation, or as directed by the online or telephone service 
and support team. Damage due to servicing that is not authorized by Dell is not 
covered by your warranty. Read and follow the safety instructions that came 
with the product.
Installation Problems
Perform the following checks if you are troubleshooting an installation 
problem:
• Check all cable and power connections (including all rack cable 
connections).
• Unplug the power cord and wait for one minute. Then reconnect the 
power cord and try again.
• If the network is reporting an error, verify that the system has enough 
memory and disk space.
• Remove all added peripherals, one at a time, and try to turn on the system. 
If after removing a peripheral the system works, it may be a problem with 
the peripheral or a configuration problem between the peripheral and the 
system. Contact the peripheral vendor for assistance.
• If the system does not power on, check the LED display. If the power 
LED is not on, you may not be receiving AC power. Check the AC power 
cord to make sure that it is securely connected.
