Connectors, LEDs, and Switches
Hot-Plug SCSI Hard Drive
The hard drive LEDs, located on each physical drive, are visible on the front of the server or
external storage unit. They provide activity, online, and fault status for each drive when
configured as part of an array and attached to a powered-on controller. Their behavior may
vary depending on the status of other drives in the array. Figure 4-8 and Table 4-8 identify
the location and status of each of the LEDs.
