HL Unit

Front LED Indicators and Buttons for Hardware Status Monitoring

On an HL unit, the following control panel buttons, icons, and LED indicators for hard-

ware status monitoring display on the right side of the front panel:

HL chassis control panel

LED Indicator Key

PWR = Power
HD = HDD Activity
NIC1 = LAN 1
NIC2 = LAN 2
OH = Overheat
UID = Unique IDentifier

The buttons and LED indicators for the depicted icons function as follows:

UID (button) – On an HL unit, when the UID button is pressed, a steady blue LED

displays on both the front and rear of the chassis (see also Rear of Chassis). These

indicators are used for easy location of the chassis in a large stack configuration.

The LED remains on until the button is pressed a second time.

Overheat/Fan Fail (icon) – This LED is unlit unless the chassis is overheated. A

flashing red LED indicates a fan failure. A steady red LED (on and not flashing)

indicates an overheating condition, which may be caused by cables obstructing the

airflow in the system or the ambient room temperature being too warm.

NIC2 (icon) – A flashing green LED indicates network activity on LAN2.

NIC1 (icon) – A flashing green LED indicates network activity on LAN1.

HDD (icon) – In addition to displaying in the control panel, this icon also displays

on the front panel on each hard drive carrier. A green LED indicates hard drive

activity. An unlit LED on a drive carrier may indicate a hard drive failure.

Power (icon) – The LED is unlit when the server is turned off. A steady green LED

indicates power is being supplied to the unit’s power supplies. (See also Rear of

Chassis.) A steady amber LED—or an unlit LED—may indicate a disconnected or

loose power supply cord.

Power (button) – When the power button is pressed, the main power to the server

is turned on. When the power button is pressed again, the main power to the server

is removed but standby power is still supplied to the server.
