System Interface Overview

HDD
Channel activity for the hard disk drive array. This light indicates disk drive activity on the server
when flashing.
Power
The LED indicates power is being supplied to the system's power supply unit. This LED should
normally be illuminated when the system is operating.
Universal Information LED
This LED will light blue when used for Unit Identifier (UID), see Figure 3-2 on page 24.
This LED will remain flashing or on until manually deactivated via the rear button or software
command.
Note: Deactivating the UID (blue indicator) LED must be performed in the same way it was
activated. If the UID LED was activated via IPMI, you can only turn the LED off via IPMI and
not with the UID button on the rear of the system.
Disk Drive Carrier LEDs
Each disk drive carrier has two LEDs.
• Green: Each drive carrier has a green LED. When illuminated, this green LED (on the front
of the drive carrier) indicates drive activity. A connection to the drive backplane enables this
LED to blink on and off when that particular drive is being accessed. See Chapter 4 for
instructions on replacing hard disk drives.
