Introduction
There are two AC Fail LEDs. Each LED is connected to its power supply independent of the other supply. The LEDs are green to indicate that the AC input to the supply is present. The LEDs turn red if the AC input to the supply is not present. If this occurs, check the LEDs on the front side of the unit. If you lose AC power from one supply cord, the LED for that supply outlet will turn red.
Figure 1–5 shows the following status LEDs: System, Controller, Disk, Temperature, DC, and Fan.
CTRL | TEMP | FAN |
STATUS | STATUS | STATUS |
SYSTEM | DISK | DC |

The SYSTEM STATUS LED is solid green when the entire storage system is operating normally.
The CTRL (CONTROLLER) STATUS LED is green when the controller is operating normally and turns red when the controller unit is failed.
The DISK STATUS LED is green when a disk enclosure is operating normally and turns amber when there is a problem.
The TEMP STATUS LED is green when the temperature sensors (6 total) indicate that the system is operating normally, amber when one (1) temp sensor indicates an
The DC STATUS LED is green when indicating normal operating status. It turns amber if there is a
The FAN STATUS LED is solid green when fans are operating normally. A flashing green LED indicates system monitoring activity such that the monitoring is being updated. The LED flashes amber if one of the fans in the module fails. If 2 or more fans fail, the LED flashes a solid red and the system will begin the shut down process at 5 seconds, for a total of 30 seconds to complete shutdown.
