2.2.3 Disk Tray
The Disk Tray houses a 3.5 inch hard disk drive. It is designed for maximum airflow
and incorporates a carrier locking mechanism to prevent unauthorized access to the
HDD.
2.2.3.1 Disk Drive Status Indicator
Every Disk Tray has 2 status indicator lights. The Disk Status Indicator light is for
Power On/Error status. When this light is
GREEN the disk drive’s power is on and
everything is functioning normally. When the light is RED , a disk error or failure has
happened that requires the user’s attention. When disk is in rebuilding status, the LED
is blinking RED.
The other status indicator light is the hard disk drive access light. Access LED will light
up blue if the SAS HD is installed. Access LED will not light up if the SATA HD is
installed. When the hard disk drive is being accessed, this light will flash
BLUE .
In addition, both indicator lights are viewable within a 170° arc.
