Basic Troubleshooting Procedures
Use the information in the following subsections to remedy basic problems you might encounter
when working with the Rackable C2112-4G3 server.
If the System Does Not Power Up
If the system serverboards will not power up when the front power buttons are pushed, use the
following checklist to identify common sources for the problem:
• Make sure that both ends of each system power cable are firmly connected to the power
supply and the corresponding power source(s) or power distribution unit (PDU).
• Check that the LED on each power supply is properly lit. The power supply has one status
LED located on the left side of the front of the power supply. The status LED has three states
as follows:
– Dark or off - indicates no AC power present
– Yellow - AC power is present, the server is not turned on (no DC power)
– Green - AC power is present and the server is turned on (DC power present)
• Make sure that the serverboard “drawers” are all firmly seated in the chassis.
