Cautions
These warnings and cautions apply throughout this chapter.
CAUTIONS
System power on/off:
The power button DOES NOT switch off system
power. To remove power from the system, you must unplug/disconnect the
power connections. Make sure power connections are
unplugged/disconnected before you open the chassis, add, or remove any
components.
Hazardous conditions, devices and cables
: Hazardous electrical
conditions may be present on power, telephone, and communication cables.
Turn off the server and disconnect the power cord, telecommunications
systems, networks, and modems attached to the server before opening it.
Otherwise, personal injury or equipment damage can result.
Electrostatic discharge (ESD) and ESD protection:
ESD can
damage disk drives, boards, and other parts. We recommend that you
perform all procedures in this chapter only at an ESD workstation. If one is
not available, provide some ESD protection by wearing an antistatic wrist
strap attached to chassis ground (any unpainted metal surface) on your server
when handling parts.
ESD and handling boards:
Always handle boards carefully. They can
be extremely sensitive to ESD. Hold boards only by their edges. After
removing a board from its protective wrapper or from the server, place the
board component side up on a grounded, static free surface. Use a
conductive foam pad if available but not the board wrapper. Do not slide
board over any surface.
Working Inside the System
This section presents the following procedures that describe removal and installation of most
components inside the system.
Safety: Before You Remove Server Covers
Before removing covers at any time to work inside the system, observe these safety guidelines.
1. Turn off all peripheral devices connected to the system.
2. Power down the system by pressing and holding the Power button on the front of the chassis for
several seconds. After the server shuts down, unplug/disconnect the power cord to remove
standby power from the server.
3. Label and disconnect all peripheral cables and all telecommunication lines connected to
I/O connectors or ports on the back of the system.
Provide electrostatic discharge (ESD) protection by wearing an anti-static wrist strap attached to
chassis ground of the system-any unpainted metal surface-when handling components.
