CAUTION:
Never operate the server for an extended period of time if an access
panel is removed. Doing so can cause thermal damage to drives and components
and can void your system warranty.
Perform the following steps:
1.
Remove the appropriate access panel, and then check the system-interlock or
system-interconnect status LEDs. For complete information, refer to your
server-specific user documentation.
2.
Remove all power sources to the server.
3.
Check the specific area.
If you cannot determine the problem by checking the specific area, perform each of
the following actions. Restart the server after each action to see if the problem has
been corrected.
WARNING: To avoid potential problems, ALWAYS read the warnings and
cautionary information in your server-specific user documentation before
removing, replacing, reseating, or modifying system components.
•
Reseat all I/O expansion boards.
•
Check all system cables and external cables for misalignment, bent pins, damage
to wiring, crimps, backward installation, or any abnormalities.
•
Check all connectors, such as cables, PCI slots, and processor slots, for foreign
material or bent pins.
•
Look for foreign material, such as screws, bits, or slot bracket blanks, that may
be short circuiting components.
Redundant Line Cord Switch
If your server has a redundant line cord switch, but you are only using one 120-volt
power cord to power your server, be sure that the power cord is connected to the
primary power plug.
Refer to your server-specific user documentation for more information on this
feature.
