Removal and replacement procedures 29
Post-installation procedure
Perform the steps below after installing or removing a server component.
7. Be sure all components are installed according to the described step-by-step instructions.
8. Check to make sure you have not left loose tools or parts inside the server.
9. Reinstall any expansion board, peripheral, and system cables that have previously been
removed.
CAUTION: Do not operate the server for more than ten minutes with the access panel and disk
drives removed. Otherwise, improper cooling airflow may damage the system components.
10. Reinstall the system covers.
11. Connect all external cables and the AC power cord to the system.
12. Press the power button on the front panel to turn on the server.
Powering down the server
The server does not completely power down when the power button is pressed. The button toggles
between On and Standby. The standby position removes power from most electronics and the drives,
but some internal circuitry remains active. To completely remove all power from the system, disconnect
all power cords from the server.
WARNING: Hazardous voltages are present inside the server. Always disconnect AC power from
the server and other associated assemblies while working inside the unit. Serious injury may result if
this warning is not observed.
WARNING: To reduce the risk of electric shock or damage to the equipment:
•
Do not disable the power cord grounding plug. The grounding plug is an important safety feature.
• Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible at all times.
• Unplug the power cord from the power supply to disconnect power to the equipment.
• Do not route the power cord where it can be walked on or pinched by items placed against it. Pay
particular attention to the plug, electrical outlet, and the point where the cord extends from the server.
CAUTION: Protect the server from power fluctuations and temporary interruptions with a regulating
uninterruptible power supply (UPS). This device protects the hardware from damage caused by
power surges and voltage spikes, and keeps the system in operation during a power failure.
1. Shut down the server as directed by the operating system documentation.
2. Press the power button to toggle to Standby.
This places the server in standby mode changing the power LED indicator to amber. In this
mode, the main power supply output is disabled. Standby does not completely disable or
remove power from the system.
3. Disconnect the AC power cord from the AC outlet and then from the server.
4. Check that the power LED indicator is turned off and that the fan noise has stopped.
5. Disconnect all external peripheral devices from the server.
