Information LED Panel The information LED panel on the front of the server contains status lights. 1 System Error Light: This amber light is lit when a system error occurs. Information about the condition will display on the Information Panel. 2 Information Panel: System monitor information appears on this vacuum fluorescent display (VFD). The Advanced Remote Management Controller monitors system functions and generates the messages. See "System Management Codes" on page 208 for more information. When the server is in standby mode (the system power supply is turned off and AC current is present) the information panel can display system monitor information. 3 System Power Light: When this light is lit, system power is present in the server. When this light flashes, the server is in standby mode (the system power supply is turned off and AC current is present). When this light is off, it indicates either power supply failure or an AC power failure. Attention: If this light is off, it does not mean there is no electrical current present in the server. To remove all electrical current from the server, you must unplug the server power cord from the electrical outlet. 4 SCSI Hard Disk Drive Activity Light: This green light is lit when there is activity on a hard disk drive. 120 Netfinity Server HMM
