Equipment log: as you integrate new parts into the system, add information about them to
your equipment log (page 163). Record the model and serial number of the system, all
installed options, and any other pertinent information specific to the system. You will need
this information when running the SSU.
Warnings and Cautions
These warnings and cautions apply throughout this manual to any procedure in which you access
the inside of the server.
WARNINGS
System power on/off:
The DC push-button on/off switch (a convex
button) on the front panel DOES NOT turn off the system AC power.
To remove power from system, you must unplug ALL AC power cords
from the wall outlet.
Hazardous conditions, devices, and cables
: Hazardous electrical
conditions may be present on power, telephone, and communication
cables. Turn off the system and disconnect all power cords,
telecommunications systems, networks, and modems attached to the
system before opening it. Otherwise, personal injury or equipment
damage can result.
CAUTIONS
Electrostatic discharge (ESD) & ESD protection:
ESD can damage
disk drives, boards, and other parts. We recommend that you do all
procedures in this chapter only at an ESD-protected 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
system 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 system, place it
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.
