Visual System Inspection

CAUTION: Do not attempt to service the system except as explained in the documentation. Only trained service technicians should remove the system cover to access any of the internal components. Refer to the documentation for your server for complete safety information before attempting to service your system.

Improperly set controls and loose or improperly connected cables are common causes of problems for external hardware components. First check all the external switches, controls, and cable connections. If this does not resolve your problem, then visually inspect the system's interior hardware for problems such as a loose card, cable connector, or mounting screw. Refer to the documentation for your server for the physical orientation of the system.

External Visual Inspection

To visually inspect the external system, follow these steps:

Inspect the status indicators that can signify component malfunction.
Turn off the system and any attached peripherals (if applicable).
Verify that all power cables are properly connected to the system, the monitor, and peripherals, and check their power sources.
Inspect connections to any attached devices including network cables, keyboard, monitor, mouse, as well as any devices attached to the serial port.

Internal Visual Inspection

To visually inspect the internal system, follow these steps:

NOTE: Before proceeding, read the safety instructions in the documentation for your system.

Turn off the system, including any attached peripherals, and disconnect all the power cables from electrical outlets.
Remove the cover (follow the procedures in the documentation for your server).

NOTE: Some components, such as the heatsink, can become extremely hot during system operations. Allow these components to cool before handling them. Use caution with sharp edges on the heatsink.

Verify that the components are fully seated in their sockets or connectors and that sockets are clean.
Check all cable connectors inside the system to verify that they are firmly attached to their appropriate connectors.
Replace the cover.
Reconnect the system and any attached peripherals to their power sources, and turn them on.

Note: You can also view the System Status screen to identify status information of all hardware components and sensors on the system. This screen enables you to easily identify components having problems, or failed components needing replacement. The component images represent the actual physical hardware components including their approximate location and size.
