Installation Problems 
Perform the following checks when you troubleshoot installation problems: 
  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. 
Troubleshooting System Startup Failure 
If your system halts during startup, especially after installing an operating 
system or reconfiguring your system’s hardware, check for invalid memory 
configurations. These could cause the system to halt at startup without any 
video output.  
 
For all other startup issues, note any system messages that appear onscreen. 
See “Using the System Setup Program” on page 58 for more information. 
Troubleshooting External Connections 
Ensure that all external cables are securely attached to the external 
connectors on your system before troubleshooting any external devices. See 
Figure 1-1 to Figure 1-6, and Figure 1-18, Figure 1-19 for the front- and 
back-panel connectors on your system.
