System Short
When powering on the server, if the power status LED blinks once every
10-20 seconds, turns amber, or stays off, the system is trying to start, but may
have a short.
CAUTION: Never operate the server with an access panel removed for an
extended period of time. Doing so may cause thermal damage to drives and
components and could void your system warranty.
Perform the following.
1. If possible, remove the appropriate access panel and check the system
interlock or system interconnect status LEDs. For complete information,
see your server’s specific troubleshooting guide.
2. Remove the power source to the server.
If you cannot determine the problem by checking the specific area, perform
one or all of the following. Restart the server after each action to see if the
problem is corrected.
■ 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 (cable, PCI slots, processor sockets, and so on) for
foreign material or bent pins.
■ Look for foreign material (screws, bits, slot bracket blanks) that may be
shorting components.
