Control Panel LEDs
The four control panels are located on the front handle of the chassis.
Each control panel has two additional LEDs.
These LEDs provide you with critical information related to different parts of the system.
This section explains what each LED indicates when illuminated and any corrective action you may need to
take.
Alert
This LED is illuminated when an alert condition occurs:
·
A solid red light indicates an overheat condition in the system
·
A flashing red light which flashes in one second intervals indicates a fan failure
·
A flashing red light which flashes in four second intervals indicates a power failure
When notified of an alert, check the routing of the cables and make sure all fans are present and operating
normally.
You should also check to make sure that the chassis covers, and air shrouds are installed.
This LED will remain flashing or on as long as the temperature is too high, or a fan does not function
properly.
NIC
Indicates network activity on either LAN1 or LAN2 when flashing.
Drive Carrier LEDs
SATA Drives
Each drive carrier has two LEDs.
·
Blue: When illuminated, this blue LED (on the front of the drive carrier) indicates
drive activity. A connection to the back-plane enables this LED to blink on and off
when that drive is being accessed
·
Red: The red LED to indicate a hard drive failure.
