Hot-Plug Hard Drive Leds - HP ProLiant ML570 Generation 2 Maintenance And Service Manual

Hot-Plug Hard Drive LEDs

Each hot-plug 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 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 4-13 and Tables 4-17 and 4-18 identify LED
locations and analyze the status of each hot-plug hard drive.
