Enterprise 220R/420R LEDsFront Panel LEDsSystem front panel LEDs provide your first indication if there is a problem with your system. Usually, a front panel LED is not the sole indicator of a problem. Error messages and even other LEDs can help to isolate the problem further.
When you first power on the system, the LEDs are individually toggled on and
off to verify that each one is working correctly. After that, the LEDs operate
as described in the following table.
Power Supply LEDsPower supply LEDs are visible from the front of the system with the doors open. The following figure shows the LEDs on the power supply in bay 0. The following table provides a description of each LED.
Disk LEDsThe disk LEDs are visible from the front of the system when the left door is open, as shown in the following figure. When a disk LED lights steadily and is green, it indicates that the slot is populated and that the drive is receiving power. When an LED is green and blinking, it indicates that there is activity on the disk.
