General Hardware Problems

WARNING: To avoid potential problems, ALWAYS read the warnings and
cautionary information in your server-specific user documentation before
removing, replacing, reseating, or modifying system components.

Loose Connections

If a device does not work, it is often because the device is not properly connected or
not properly seated. Good device connections are essential to a functioning server. To
ensure that each device is properly connected and seated:
1. Be sure that all power cords are properly connected. If any are not, plug the
power cord in firmly and correctly.
2. Be sure that the cables of all components, such as the monitor, keyboard, mouse,
and any external or internal devices, are securely connected.
3. If a fixed cable tray is available for your server, make sure that the cords and
cables connected to the server are correctly routed through the tray.
4. Be sure that all cables are lined up properly with any connector pins in the
sockets to which they connect. Be sure that there are no bent connectors.
5. Be sure that each device is properly seated by pushing in the device.
6. If a device has latches, be sure that they are completely closed and locked.
7. If problems continue to occur, remove each device, reinstall it, and then firmly
push it in again.

Cabling Order

On some systems, electrical damage can occur to peripheral devices if the power cord
and device cables are connected to the server in an improper sequence. Refer to the
cabling requirements in your server-specific user documentation for more
information on the proper way to connect the cables to your server.
