Before You Begin
Whether to Use the LED Status Connector
3ware RAID controllers include two types of LED status connectors:
Overall indicator, which lights when any drive is active.
Individual LED indicators, for each drive. (Not supported on chassis that have a common ground.)
If you are building a system from scratch, you may want to consider using a chassis or drive carrier that is compatible with the 3ware RAID controller activity LEDs, such as the AMCC
For more information, see “Additional Details About the LED Status Connectors” on page 13.
Most chassis have a single drive activity cable that you can connect to the overall activity indicator on the 3ware 9000 controller. For the location of the overall drive activity connector, see the figure for the appropriate controller in the installation sections starting on page 12, and refer to Table 1, “LED Indicator Pin Positions,” on page 14.
Drive Installation Considerations
Selecting an enclosure. If you are planning to use RAID 1, 5, 10, or 50, you may want to consider installing drives into hot- swappable enclosures, so that they can be easily removed in the event of a drive failure.
When to install the drive. If the drives are not already installed in your computer, you can choose to install them either before or after connecting the interface cables to them.
