LED Indicator

Description

 

 

Hard-drive status indicator

The green hard-drive status indicator lights up when the drive

 

is ready and is functioning normally. The status indicator is off

 

when the drive is absent and is not configured as part of a RAID

 

or non-RAID volume or cannot be detected by the operating

 

system or RAID controller.

 

The green status indicator blinks when a volume of which the

 

drive is a member is rebuilding.

 

The amber status indicator blinks when a fault occurs with the

 

drive.

 

 

NIC1 and NIC2 link indicators

The indicators for the two integrated network adapters light

 

green if the network adapters are connected to the network.

 

The indicators flash green when data is being transmitted.

 

 

Power indicator

The green indicator flashes if AC power is available to the

 

system, but the system is not powered on.

 

The green indicator is on when the system is powered on.

 

If the system is not connected to AC power, the green indicator

 

is off.

 

 

The power button provides the ability to soft switch the power cycling to the system.

The two system identification buttons on the front and back panels can be used to locate a particular system within a rack. When one of these buttons is pushed or the system management software is used to identify the system, the blue system status indicators on the front and back of the system blink. (To stop the indicator from blinking press one of the identification buttons a second time, or use the systems management software.)

The front panel also incorporates a USB connector that is accessible when the bezel is removed. See Figure 2-4.
