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 4-19 and Table 4-17 to identify LED locations and functions.
