Chapter 3: System Interface
3-3
•
Power: The main power button on each of the four control panels is used to
apply or remove power from the power supply to each of the four systems in
the chassis. Turning off system power with this button removes the main power,
but keeps standby power supplied to the system. Therefore, you must unplug
system before servicing. The poer button has a built-in LED which will turn green
when the power is on.
•
UID: When used with a UID compatible motherboard, the UID button is used
to turn on or off the blue light function of the LED. This is built into the front
side of the UID button and at the rear end of each motherboard node, for those
motherboards which support it. Once the blue light is activated, the unit can be
easily located in very large racks and server banks.
3-3 Drive Carrier LEDs
The F424BD chassis supports hot-swappable 2.5" SAS/SATA drives include the
following LED indicators.
SAS/SATA Drives
Each SAS/SATA drive carrier has two LEDs.
•
Blue: Each Serial ATA drive carrier has a blue LED. When illuminated, this blue
LED (on the front of the SATA drive carrier) indicates drive activity. A connection
to the SATA backplane enables this LED to blink on and off when that particular
drive is being accessed.
•
Red: The red LED to indicate an SAS/SATA drive failure. If one of the SAS/
SATA drives fail, you should be notifi ed by your system management software.
SCSI Drives
This chassis does not support SCSI drives.
