Safety First—For You and Your Enclosure
CAUTION:
Many repairs may only be done by a certified service technician.
You should only perform troubleshooting and simple repairs as authorized in
your product documentation, or as directed by the online or telephone service
and support team. Damage due to servicing that is not authorized by Dell is not
covered by your warranty. Read and follow the safety instructions that came
with the product.
Troubleshooting Enclosure Startup Failure
If your system halts during startup, check if:
• The enclosure emits a series of beeps. See "Enclosure Alarms" on page 16.
• The enclosure fault LEDs are lit. See "Enclosure Management Module" on
page 13.
• A message is displayed on the screen. See the Dell™ OpenManage™ Server
Administrator documentation.
• There is a constant scraping or grinding sound when you access the hard
drive. See "Getting Help" on page 57.
Troubleshooting Loss of Communication
For information about troubleshooting loss of communication, see
"Troubleshooting Enclosure Management Modules" on page 52.
Troubleshooting External Connections
• Verify that the cables are connected to the correct ports before
troubleshooting any external devices. For the location of the back-panel
connectors on your enclosure, see Figure 1-5.
• Ensure that all the cables are securely attached to the external connectors
on your enclosure.
