11.5 Hard Drive LED Indicators

Each disk drive carrier has two LED indicators visible from the front of the system. One is a
green LED for disk activity and the other is a bicolor (Green/Amber) LED for status
information. The activity LED is driven by the disk drive during normal operation. The bicolor
LED is controlled by the SEP device on the backplane. Both LEDs are used to indicate certain
conditions under direction of a storage controller.

Optical drives are optional in all M610x systems and connect to the blade through the front
USB interface. The following internal slim-line drives are available on the M610x: DVD-ROM
