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.
