Removal and Replacement Procedures

To power down the server:

1.Press the power button to toggle to Standby. This places the server in standby mode, disabling the main power supply output and providing auxiliary power to the server. Standby does not completely disable or remove power from the system.

2.Be sure that the system LED closest to the right on the front panel is amber and that the fan noise has stopped.

3.Disconnect the AC power cord from the AC outlet, and then from the server.

4.Disconnect all external peripheral devices from the server.

Rack Stability Warning

For stability and safety, properly positioning the server is critical.

WARNING: To reduce the risk of personal injury or damage to the equipment, be sure that:

•The leveling jacks are extended to the floor.

•The full weight of the rack rests on the leveling jacks.

•The stabilizing feet are connected to the rack if it is a single-rack installation.

•The racks are coupled together in multiple-rack installations.

•Only one component is extended at a time. A rack may become unstable if more than one component is extended for any reason.
