To power down the server:
1. Press the server Power On/Off switch to power down the server. When the server is off,
the power LED deactivates.
2. Verify that the fan is off by listening for the fan noise to stop.
3. Disconnect the power cord first from the AC outlet and then from the server.
4. Disconnect all remaining cables on the server rear panel, including cables extending from
external connectors on expansion boards.
5. For stability and safety, position the server securely on a workbench or other solid surface.
The system is now without power and can be serviced safely.
Access Panel
To access the system board, processor, memory modules, expansion slot, and other internal
components, you must remove the access panel. Observe the following warnings and
cautions.
WARNING: The front panel Power On/Off switch does not completely shut off all
system power. Portions of the power supply and some internal circuitry remain active
until AC power is removed.
WARNING: To reduce the risk of personal injury from hot surfaces, allow the internal
system components to cool before touching them.
CAUTION: Do not operate the server without the access panel installed because it is
required for proper airflow. Operating the server without its access panel prevents proper
airflow that results in improper cooling and possible thermal damage.
CAUTION: Before removing the server access panel, be sure that the server is powered
down and that the power cord is disconnected from the server or the electrical outlet.
CAUTION: To avoid the risk of damage to your system or expansion boards, remove all
power cords before installing or removing expansion boards. When the Power On/Off switch
is in the off position, auxiliary power is still connected to the PCI expansion slot and may
damage the card.
CAUTION: Electrostatic discharge can damage electronic components. Ensure proper
grounding before beginning any installation procedure.
