Hot-Plug SCSI Hard Drives
Each hot-plug SCSI hard drive has three LED indicators located on the front of the drive. The
LEDs provide activity, online, and fault status for each corresponding drive when configured
as a part of an array and attached to a powered-on Smart Array controller. Their behavior
may vary depending on the status of other drives in the array. Use Figure 4-6 and Table 4-5 to
identify LED locations and functions.
