The internal health LED identifies service events for internal components in a
pre-failure or failed condition. Internal components include fans, processors, PPMs,
memory, and overtemperature conditions. For a list of these events, refer to
Appendix D, “Troubleshooting.”
Hot-Plug SCSI Hard Drive LEDs
Each hot-plug SCSI hard drive has three LEDs located on the front of the drive. They
provide activity, online, and fault status for each corresponding drive when
configured as a part of an array and attached to an active Smart Array Controller.
LED behaviors may vary, depending on the status of other drives in the array.
Figure E-2 and Tables E-2 and E-3 identify LED locations and status of each
hot-plug SCSI hard drive.
CAUTION: Before removing a hard drive, refer to the Servers Troubleshooting
Guide for information regarding hot-plug hard drive replacement guidelines.
