PPMs, memory, and overtemperature conditions. For a list of these events, see
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. Use the following figure and tables to identify LED
locations and analyze the status of each hot-plug SCSI hard drive.
CAUTION: Read the “Hot-Plug Hard Drive Replacement Guidelines” in the
Compaq Servers Troubleshooting Guide before removing a hard drive
