The drive has been spun down by a user request (Prepare to Remove operation), or had a rebuild operation on it aborted by a user action or due to any reason other than a drive failure.

In RAID configurations, the drive-status indicator lights to indicate the status of the drive.

NOTE: For non-RAID configurations, only the drive-activity indicator is active. The drive-status indicator is off.

Table 1-2lists the drive indicator patterns for RAID hard drives. Different patterns are displayed as drive events occur in the system. For example, if a hard drive fails, the "drive failed" pattern appears. After the drive is selected for removal, the "drive being prepared for removal" pattern appears, followed by the "drive ready for insertion or removal" pattern. After the replacement drive is installed, the "drive being prepared for operation" pattern appears, followed by the "drive online" pattern.

Connecting External Devices

When connecting external devices to your system, follow these guidelines:

•Most devices must be connected to a specific connector and device drives must be installed before the device operates properly. (Device drivers are normally included with your operating system software or with the device itself.) See the documentation that accompanied the device for specific installation and configuration instructions.

•Always attach external devices while your system and the device are turned off. Next, turn on any external devices before turning on the system (unless the documentation for the device specifies otherwise).
