This chapter describes the front-panel and back-panel LEDs, which display the operating status of all drives and modules. Topics covered in this chapter are:
5.1 LEDs When Array is First Powered On
With the array powered up, but not connected to a server, you should see the LED conditions described in TABLE 5-1 and TABLE 5-2.

Drive LEDs
|
Solid green, if media scan off
Blinking green, if media scan on
|
|
Chassis ear LEDs
|
Solid green
|
| Note - Whenever media scan is running on a drive, its front-panel LED flashes green. It is normal for front-panel drive LEDs to flash green while media scanning is running. Media scan is disabled by default. It can be enabled to start when the array is powered up. For more information, refer to the Sun StorEdge 3000 Family RAID Firmware User’s Guide.

5.2 Front-Panel LEDs
The drive LEDs are located between the rows of drives on the front panel (see the following figure). The system operation LEDs are located on the right ear of the chassis.
FIGURE 5-1 Front-Panel LEDs
The following figure shows the front panel LEDs and the Reset button.
Use a paperclip to push the Reset button to silence a failed component alarm without affecting LEDs. See Section 6.4, Silencing Audible Alarms for more information about silencing audible alarms.

For more information about temperature sensors, refer to the Sun StorEdge 3000 Family RAID Firmware User’s Guide.
| Note - To test that the LEDs work, using a paperclip, press and hold the Reset button for 5 seconds. All the LEDs should change from green to amber when you perform this test. Any LED that fails to light indicates a problem with the LED. When you release the Reset button, the LEDs return to their initial state.
|
5.2.1 Drive LED Status
The drive LED color changes based on array events. For example, when a media scan is performed, to indicate an event is taking place, the drive LEDs blink green for the physical drives that compose the logical drive that is being scanned. The following table lists the events that influence the drive LED status.

The Sun StorEdge Configuration Service CLI set led command is run, or the firmware option “Flash All Drives” is used.
|
| Note - Whenever media scan is running on a drive, its front-panel LED flashes green. It is normal for front-panel drive LEDs to flash green while media scanning is running. Media scan is disabled by default. It can be enabled to start when the array is powered up. For more information, refer to the Sun StorEdge 3000 Family RAID Firmware User’s Guide.

5.3 Back-Panel LEDs
The back-panel LED colors indicate the conditions described in the following figures and tables. The following figure is the back-panel with LEDs.
FIGURE 5-3 Back-Panel LEDs
If you see a blinking green or amber LED, you might have an incorrect configuration or a failed component.
| Note - To test that the LEDs work, using a paperclip, press and hold the Reset button for 5 seconds. All the LEDs should change from green to amber when you perform this test. Any LED that fails to light indicates a problem with the LED. When you release the Reset button, the LEDs return to their initial state.

| Note - The batteries in controller FRUs experience discharge during shipment and might require an extended charging cycle upon initial power-up. Nominal battery operation is achieved when the battery status LED changes from amber to flashing green within 25 minutes after the initial power cycle. If the battery status LED remains amber for more than 25 minutes after the initial power-up, then the unit must be power cycled to initiate the extended charging cycle. If the battery status LED remains amber for more than 30 minutes after initiating the extended charging cycle, contact Sun service personnel for additional instructions.
