Checking the LEDs
The LEDs indicate the status of the storage subsystem and components. Green
LEDs indicate a normal operating status; amber LEDs (needs attention) indicate a
possible failure; a blue LED on a component indicates that it is safe to remove that
component.
The DS3200 also has a blue system locator LED that is lit when the menu function
is selected in the Subsystem Management window, causing the Locate command to
be sent to the DS3200.
Check all the LEDs on the front and rear of the storage subsystem when you turn
on the power. During power-on, the LEDs flash intermittently as the storage
subsystem and components complete the power-on process. In addition to checking
for faults, you can use the LEDs on the front of the storage subsystem to determine
whether the drives are responding to I/O transmissions from the host.
Power-supply LEDs
This section describes the primary LEDs on the DS3200 power supplies.
DC power LED (green)
When this green LED is lit, it indicates that the DS3200 is turned on and is
supplying both 5-volt and 12-volt dc power to the DS3200.
OK to remove LED (blue)
When this blue LED is lit, it indicates that it is safe to remove the
power-supply unit.
Fault LED (amber)
When this amber LED is lit, it indicates that a power supply or fan has
failed or that a redundant power supply is not turned on.
AC power LED (green)
When this green LED is lit, it indicates that the DS3200 is receiving ac
power.
