Basic Troubleshooting Procedures
Use the information in the following subsections to remedy basic problems you might encounter
when working with the Rackable C2110G-RP5 server.
If the System Does Not Power Up
If the system will not power up when the front power button is 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 to see if the power fail LED is lit on the front of the unit. This LED should be off if
the system is operating normally.
• 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 LED has three states:
– 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)
• Open the system cover, remove the air shroud and check to make sure that no obvious short
circuits exist between the serverboard and chassis.
