First steps checklist
• AC power available at the wall outlet?
• Are the power supplies plugged in? Check the AC cable(s) on the
back of the chassis and at the AC source.
• Are all cables correctly connected and secured?
• Is the processor fully seated in the socket on the mainboard?
• Are all standoffs in the proper location and not touching any
components, causing a potential short?
• Are all expansion boards fully seated in their slots on the PCI riser
assembly?
• Are all jumper settings on the mainboard correct?
• Are all jumper and switch settings on expansion boards and
peripheral devices correct? If applicable, ensure that there are no
conflicts - for example, two expansion boards sharing the same
interrupt.
• Are all peripheral devices installed correctly?
• Are all device drivers properly installed?
• Are the configuration settings made in the BIOS setup correct?
• Is the operating system properly loaded? Refer to the operating
system documentation.
• Did you press the system power button on the front panel to turn
the server on (power indicator should be lit)?
• Is the system power cord properly connected to the system and
plugged into an outlet for 100-127 V or 200-240 V?
• Are all integrated components from the tested components lists?
Check the tested memory, and chassis lists, as well as the supported
hardware and operating system list.
