2-4 Compaq ProLiant ML370 Maintenance and Service Guide
WARNING: To reduce the risk of personal injury or damage to the equipment: If the server is
mounted in a rack, internal devices may not be accessible for removal and replacement. If the
server must be removed from the rack for device accessibility, remove the server from the rack
and place it on a sturdy table or workbench. Refer to the ProLiant ML370 Servers Setup and
Installation Guide for further information on working with racks.
CAUTION: The system power in the server does not completely shut off from the front Power
On/Standby switch. Moving the switch from On to Standby leaves some portions of the hot-plug
power supply and some internal circuitry active. Disconnect all power cords from the server to
remove all power from the system.
CAUTION: Electrostatic discharge can damage electronic components. Be sure you are
properly grounded before beginning any installation procedure. For more information, see the
section titled “Electrostatic Discharge Information” earlier in this chapter.
To power down the server:
1. Press the Power On/Standby switch to Standby. This places the server in standby mode,
thereby disabling the main power supply output and providing auxiliary power to the
server. Standby does not completely remove power from the system.
2. Verify that the system power LED indicator on the front panel, near the Power
On/Standby switch, is amber and that the fan noise stops.
3. Disconnect all AC power cords from the AC outlet, then from the server.
4. Disconnect all external peripheral devices from the server.
5. For stability and safety, properly positioning the server is critical. If the server is mounted
in a rack, remove the rack model server from the rack and place it on a sturdy table or
workbench. Refer to the ProLiant ML370 Servers Setup and Installation Guide for
instructions.
Rack Warnings
WARNING: To reduce the risk of personal injury, make sure that the rack is adequately
stabilized before extending a component outside the rack. A rack may become unstable if more
than one component is extended for any reason. Extend only one component at a time.
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 stabilizers are attached to the rack if it is a single rack installation.
■ The racks are coupled together in multiple rack installations.
