Safety First—For you and Your Array
CAUTION: Many repairs may only be done by a certified service technician.
You must 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 Storage Array Startup Failure
If your system halts during startup, check if:
• The array emits a series of beeps.
• The array fault LEDs are lit. See "RAID Controller Modules" on page 31.
• There is a constant scraping or grinding sound when you access the hard
drive. See "Getting Help" on page 283.
Troubleshooting Loss of Communication
For information about troubleshooting loss of communication, see
"Troubleshooting Array and Expansion Enclosure Connections" on page 279.
Troubleshooting External Connections
• Verify that the cables are connected to the correct ports before
troubleshooting any external devices. To locate the back-panel connectors
on your array, see Figure 3-1.
• Ensure that all the cables are securely attached to the external connectors
on your array.
• For information on cabling, see the Dell PowerVault MD3600i Deployment
